Cannabidiol CBD is one of the most important compounds in Cannabis sativa, lacks psychotropic effects, and possesses a high number of therapeutic properties including the amelioration of experimental autoimmune encephalomyelitis EAE.

    In the central nervous system, the extent of cell infiltration, axonal damage, demyelination, microglial activation and cannabinoid receptors expression was assessed by immunohistochemistry. Lymph cell viability, apoptosis, oxidative stress and IL-6 production were measured in vitro. Preventive intraperitoneal treatment with CBD ameliorated the clinical signs of at-EAE, and this improvement was accompanied by a reduction of the apparent diffusion coefficient in the subiculum area of the brain.

    Inflammatory infiltration, axonal damage, and demyelination were reduced, and cannabinoid receptor expression was modulated. Incubation with CBD decreased encephalitogenic cell viability, increasing early apoptosis and reactive oxygen species ROS and decreasing IL-6 production. CBD markedly improved the clinical signs of at-EAE and reduced infiltration, demyelination and axonal damage.

    The CBD -mediated decrease in the viability of encephalitogenic cells involves ROS generation, apoptosis and a decrease in IL-6 production and may contribute to the therapeutic effect of this compound. Cannabidiol monotherapy for treatment-resistant schizophrenia. Cannabidiol CBD , one of the major products of the marijuana plant, is devoid of marijuana's typical psychological effects.

    In contrast, potential antipsychotic efficacy has been suggested based on preclinical and clinical data Zuardi et al. In this report, we further investigated the efficacy and safety of CBD monotherapy in three patients with treatment-resistant schizophrenia TRS.

    This was an in-patient study. On the 36th day, CBD treatment was discontinued and replaced by placebo for 5 days, which was subsequently switched to olanzapine for over 15 days. Efficacy, tolerability and side effects were assessed. One patient showed mild improvement, but two patients didn't show any improvement during CBD monotherapy.

    All patients tolerated CBD very well and no side effects were reported. Schizophrenia-related psychosis is associated with disturbances in mesolimbic dopamine DA transmission, characterized by hyperdopaminergic activity in the mesolimbic pathway.

    Currently, the only clinically effective treatment for schizophrenia involves the use of antipsychotic medications that block DA receptor transmission. However, these medications produce serious side effects leading to poor compliance and treatment outcomes. Emerging evidence points to the involvement of a specific phytochemical component of marijuana called cannabidiol CBD , which possesses promising therapeutic properties for the treatment of schizophrenia-related psychoses.

    However, the neuronal and molecular mechanisms through which CBD may exert these effects are entirely unknown. We used amphetamine AMPH -induced sensitization and sensorimotor gating in rats, two preclinical procedures relevant to schizophrenia-related psychopathology, combined with in vivo single-unit neuronal electrophysiology recordings in the ventral tegmental area, and molecular analyses to characterize the actions of CBD directly in the nucleus accumbens shell NASh , a brain region that is the current target of most effective antipsychotics.

    Our findings demonstrate a novel mechanism for the putative antipsychotic-like properties of CBD in the mesolimbic circuitry. We identify the molecular signaling pathways through which CBD may functionally reduce schizophrenia-like neuropsychopathology. However, the mechanisms by which. The cannabis-derived phytochemical, cannabidiol CBD , has been shown to have pharmacotherapeutic efficacy for the treatment of schizophrenia.

    However, the mechanisms by which CBD may produce. CBD spray and MS spasticity symptoms: A randomized, placebo controlled long-term follow-up clinical trial with THC: CBD spray versus placebo demonstrated that it was not associated with cognitive decline, depression or significant mood changes after 12 months of treatment.

    CBD oromucosal spray did not adversely influence standard driving ability in patients with moderate to severe MS spasticity. Other new long term observational data about the use of THC: Findings to date reinforce the efficacy and safety observed in Phase III clinical trials. It is of interest that in practice average dosages used by patients tended to be lower than those reported in clinical studies Thus, these new data support a positive benefit-risk relationship for THC: CBD oromucosal spray during longer-term use.

    Symmetric corticobasal degeneration S- CBD. Corticobasal degeneration CBD is a neurodegenerative disease characterized pathologically by neuronal loss, gliosis and tau deposition in neocortex, basal ganglia and brainstem. Typical clinical presentation is known as corticobasal syndrome CBS and involves the core features of progressive asymmetric rigidity and apraxia, accompanied by other signs of cortical and extrapyramidal dysfunction. Asymmetry is also emphasized on neuroimaging.

    Clinical records were reviewed and quantitative volumetric analysis of symmetric atrophy on head MRI using atlas based parcellation was performed. Subjects were classified as S- CBD if no differences had been observed between right- and left-sided cortical or extrapyramidal signs or symptoms.

    Five cases 2 female met criteria for S- CBD. None had limb dystonia, myoclonus, apraxia or alien limb phenomena. CBD can have a symmetric presentation, clinically and radiologically, in which typical features of CBS, such as limb apraxia, myoclonus, dystonia and alien limb phenomenon, may be absent. Copyright c Elsevier Ltd. Human Gingival Mesenchymal Stem Cells hGMSCs are multipotential cells that can expand and differentiate in culture under specific and standardized conditions.

    In the present study, we have investigated whether in vitro pre-treatment of hGMSCs with Cannabidiol CBD can influence their expression profile, improving the therapeutic potential of this cell culture.

    In conclusion, the present study will provide a new simple and reproducible method for preconditioning hGMSCs with CBD , before transplantation, as an interesting strategy for improving the hGMSCs molecular phenotype, reducing the risk of immune or inflammatory reactions in the host, and in parallel, for increasing their survival and thus, their long-term therapeutic efficacy.

    Impact of enzymatic and alkaline hydrolysis on CBD concentration in urine. A sensitive and specific analytical method for cannabidiol CBD in urine was needed to define urinary CBD pharmacokinetics after controlled CBD administration, and to confirm compliance with CBD medications including Sativex-a cannabis plant extract containing 1: Non-psychoactive CBD has a wide range of therapeutic applications and may also influence psychotropic smoked cannabis effects.

    Solid-phase extraction isolated and concentrated analytes prior to GC-MS. Enzyme-hydrolyzed urine specimens exhibited more than a fold CBD concentration increase compared to alkaline and non-hydrolyzed specimens. This method can be applied for urinary CBD quantification and further pharmacokinetics characterization following controlled CBD administration.

    A sensitive and specific analytical method for cannabidiol CBD in urine was needed to define urinary CBD pharmacokinetics after controlled CBD administration, and to confirm compliance with CBD medications including Sativex—a cannabis plant extract containing 1: Alzheimer's disease AD is a neurodegenerative disease, in which the primary etiology remains unknown. AD shows oxidative stress and chronic inflammation. Cannabidiol CBD is a non-psychotomimetic phytocannabinoid from Cannabis sativa plant.

    CBD attenuates oxidative stress and diminishes mitochondrial dysfunction and reactive oxygen species generation. For permissions, please e-mail: Diabetic retinopathy is characterized by blood-retinal barrier BRB breakdown and neurotoxicity. These pathologies have been associated with oxidative stress and proinflammatory cytokines, which may operate by activating their downstream target p38 MAP kinase.

    In the present study, the protective effects of a nonpsychotropic cannabinoid, cannabidiol CBD , were examined in streptozotocin-induced diabetic rats after 1, 2, or 4 weeks. Retinal cell death was determined by terminal dUTP nick-end labeling assay; BRB function by quantifying extravasation of bovine serum albumin-fluorescein; and oxidative stress by assays for lipid peroxidation, dichlorofluorescein fluorescence, and tyrosine nitration.

    Experimental diabetes induced significant increases in oxidative stress, retinal neuronal cell death, and vascular permeability. These results demonstrate that CBD treatment reduces neurotoxicity, inflammation, and BRB breakdown in diabetic animals through activities that may involve inhibition of p38 MAP kinase.

    Asthma represents a public health problem and traditionally is classified as an atopic disease, where the allergen can induce clinical airway inflammation, bronchial hyperresponsiveness, and reversible obstruction of airways.

    Studies have demonstrated the presence of T-helper 2 lymphocytes in the lung of patients with asthma. These cells are involved in cytokine production that regulates immunoglobulin synthesis. Asthma was induced in 8-week-old Wistar rats by ovalbumin OVA. CBD treatment was able to decrease the serum levels of all analyzed cytokines except for IL levels. CBD seems to be a potential new drug to modulate inflammatory response in asthma. Several publications have suggested increasing cannabis potency over the last decade, which, together with lower amounts of cannabidiol CBD , could contribute to an increase in adverse effects after cannabis smoking.

    This study aimed to investigate the relationship between THC- and CBD concentrations in blood samples among cannabis users, and to compare cannabinoid concentrations with the outcome of a clinical test of impairment CTI and between traffic accidents and non-accident driving under the influence of drugs DUID -cases. Seizure sample analysis did not reveal high potency cannabis products, and while CBD content appeared high in hashish, it was almost absent in marijuana.

    Purified Cannabidiol , the main non-psychotropic component of Cannabis sativa, alone, counteracts neuronal apoptosis in experimental multiple sclerosis. Multiple Sclerosis MS is a global concern disease leading to a progressive, chronic and demyelinating condition, affecting the central nervous system CNS.

    The present study was designed to test the effects of intraperitoneal administration of cannabidiol CBD , the main non-psychotropic cannabinoid of Cannabis sativa CS , in an experimental model of MS. The aim is to evaluate the capability of CBD administration to thwart the cascade of mediators involved in MS-induced apoptosis. After immunization, mice were observed daily for signs of EAE and weight loss. Disease signs were evaluated using a standardized scoring system.

    Moreover, CBD interferes with pp21 axis activation. As results, the absence of tissue apobody formation in spinal cord tissues of EAE-mice treated with CBD was established.

    Most of therapeutic properties of CS are currently ascribed to the psychotropic effects of phenylterpenoid delta-9 tetrahydrocannabinol. We have demonstrated that, alone, purified CBD possesses an anti-apoptotic power against the neurodegenerative processes underlying MS development. This represents an interesting new profile of CBD that could lead to its introduction in the clinical management of MS.

    Cannabinoids have been shown to exert anti-inflammatory activities in various in vivo and in vitro experimental models as well as ameliorate various inflammatory degenerative diseases. However, the mechanisms of these effects are not completely understood. Using the BV-2 mouse microglial cell line and lipopolysaccharide LPS to induce an inflammatory response, we studied the signaling pathways engaged in the anti-inflammatory effects of cannabinoids as well as their influence on the expression of several genes known to be involved in inflammation.

    The cannabinoid anti-inflammatory action does not seem to involve the CB1 and CB2 cannabinoid receptors or the abn- CBD -sensitive receptors. The anxiolytic effects of cannabidiol in chronically stressed mice are mediated by the endocannabinoid system: Role of neurogenesis and dendritic remodeling. Repeated injections of cannabidiol CBD , the major non-psychotomimetic compound present in the Cannabis sativa plant, attenuate the anxiogenic effects induced by Chronic Unpredictable Stress CUS.

    The specific mechanisms remain to be fully understood but seem to involve adult hippocampal neurogenesis and recruitment of endocannabinoids. Golgi staining and immunofluorescence revealed that these effects were associated with an increase in hippocampal neurogenesis and spine density in the dentate gyrus of the hippocampus. Cannabidiol , a Cannabis sativa constituent, as an antipsychotic drug. A high dose of delta9-tetrahydrocannabinol, the main Cannabis sativa cannabis component, induces anxiety and psychotic-like symptoms in healthy volunteers.

    These effects of delta9-tetrahydrocannabinol are significantly reduced by cannabidiol CBD , a cannabis constituent which is devoid of the typical effects of the plant. Studies in animal models and in healthy volunteers clearly suggest an anxiolytic-like effect of CBD.

    The antipsychotic-like properties of CBD have been investigated in animal models using behavioral and neurochemical techniques which suggested that CBD has a pharmacological profile similar to that of atypical antipsychotic drugs. The results of two studies on healthy volunteers using perception of binocular depth inversion and ketamine-induced psychotic symptoms supported the proposal of the antipsychotic-like properties of CBD.

    In addition, open case reports of schizophrenic patients treated with CBD and a preliminary report of a controlled clinical trial comparing CBD with an atypical antipsychotic drug have confirmed that this cannabinoid can be a safe and well-tolerated alternative treatment for schizophrenia. Future studies of CBD in other psychotic conditions such as bipolar disorder and comparative studies of its antipsychotic effects with those produced by clozapine in schizophrenic patients are clearly indicated.

    Could cannabidiol be used as an alternative to antipsychotics? Individuals with this disorder often present signs such as hallucination, anxiety, reduced attention, and social withdrawal. Although antipsychotic drugs remain the cornerstone of schizophrenia treatment, they are associated with severe side effects. Recently, the endocannabinoid system ECS has emerged as a potential therapeutic target for pharmacotherapy that is involved in a wide range of disorders, including schizophrenia.

    Since its discovery, a lot of effort has been devoted to the study of compounds that can modulate its activity for therapeutic purposes. Among them, cannabidiol CBD , a non-psychoactive component of cannabis, shows great promise for the treatment of psychosis, and is associated with fewer extrapyramidal side effects than conventional antipsychotic drugs.

    The overarching goal of this review is to provide current available knowledge on the role of the dopamine system and the ECS in schizophrenia, and to discuss key findings from animal studies and clinical trials investigating the antipsychotic potential of CBD. Cannabidiol in medical marijuana: Research vistas and potential opportunities.

    The high and increasing prevalence of medical marijuana consumption in the general population invites the need for quality evidence regarding its safety and efficacy. Herein, we synthesize extant literature pertaining to the phytocannabinoid cannabidiol CBD and its brain effects.

    The effect of CBD on brain systems as well as on phenomenological measures e. Cannabidiol is without euphoriant properties, and exerts antipsychotic, anxiolytic, anti-seizure, as well as anti-inflammatory properties.

    It is essential to parcellate phytocannabinoids into their constituent moieties as the most abundant cannabinoid have differential effects on physiologic systems in psychopathology measures. Interventional studies with purified CBD are warranted with a call to target-engagement proof-of-principle studies using the research domain criteria RDoC framework. Cannabidiol CBD has been traditionally used in Cannabis -based preparation, however historically, it has received far less interest as a single drug than the other components of Cannabis.

    Currently, CBD generates considerable interest due to its beneficial neuroprotective, antiepileptic, anxiolytic, antipsychotic, and anti-inflammatory properties. Therefore, the CBD scaffold becomes of increasing interest for medicinal chemists. This review provides an overview of the chemical structure of natural and synthetic CBD derivatives including the molecular targets associated with these compounds.

    A clear identification of their biological targets has been shown to be still very challenging. Cannabidiol CBD has been traditionally used in Cannabis-based preparation, however historically, it has received far less interest as a single drug than the other components of Cannabis.

    Cannabidiol inhibits angiogenesis by multiple mechanisms. The non-psychoactive cannabinoid cannabidiol CBD effectively inhibits the growth of different types of tumours in vitro and in vivo and down-regulates some pro-angiogenic signals produced by glioma cells. As its anti-angiogenic properties have not been thoroughly investigated to date, and given its very favourable pharmacological and toxicological profile, here, we evaluated the ability of CBD to modulate tumour angiogenesis.

    These effects were associated with the down-modulation of several angiogenesis-related molecules. Its dual effect on both tumour and endothelial cells supports the hypothesis that CBD has potential as an effective agent in cancer therapy. Several studies have demonstrated anti-proliferative and pro-apoptotic actions of cannabinoids on various tumours, together with their anti-angiogenic properties. Firstly, we evaluated the effect of CBD on human umbilical vein endothelial cell HUVEC proliferation and viability - through [3- 4,5-dimethylthiazolyl -2,5-diphenyltetrazolium bromide] assay and FACS analysis - and in vitro motility - both in a classical Boyden chamber test and in a wound-healing assay.

    This study reveals that CBD inhibits angiogenesis by multiple mechanisms. Mechanisms of cannabidiol neuroprotection in hypoxic-ischemic newborn pigs: The mechanisms underlying the neuroprotective effects of cannabidiol CBD were studied in vivo using a hypoxic-ischemic HI brain injury model in newborn pigs. Therefore we investigated, in Wistar rats, effects of pulmonary, oral and subcutaneous sc. While cannabinoid serum and brain levels rapidly peaked and diminished after pulmonary administration, sc.

    In contrast, oral CBD produced mild hyperlocomotion. In conclusion, oral administration yielded the most pronounced behavioural effects which corresponded to the highest brain levels of cannabinoids. Of central importance was the novel finding that THC can be detected in serum and brain after administration of CBD alone which, if confirmed in humans and given the increasing medical use of CBD -only products, might have important legal and forensic ramifications.

    In the past five years, an increasing number of publications have focused on the discovery of the anti-inflammatory, anti-oxidant, and neuroprotective effects of CBD. In particular, CBD exerts positive pharmacological effects in ischemic stroke and other chronic diseases, including Parkinson's disease, Alzheimer's disease, and rheumatoid arthritis.

    Importantly, CBD use does not lead to tolerance. In this review, we will discuss the therapeutic possibility of CBD as a cerebroprotective agent, highlighting recent pharmacological advances, novel mechanisms, and therapeutic time window of CBD in ischemic stroke. Cannabis contains the psychoactive component delta9-tetrahydrocannabinol delta9-THC , and the non-psychoactive components cannabidiol CBD , cannabinol, and cannabigerol.

    It is well-known that delta9-THC and other cannabinoid CB1 receptor agonists are neuroprotective during global and focal ischemic injury.

    Additionally, delta9-THC also mediates psychological effects through the activation of the CB1 receptor in the central nervous system. In addition to the CB1 receptor agonists, cannabis also contains therapeutically active components which are CB1 receptor independent. The cerebroprotective action of CBD is CB1 receptor-independent, long-lasting, and has potent anti-oxidant activity. Doxorubicin DOX is a widely used, potent chemotherapeutic agent; however, its clinical application is limited because of its dose-dependent cardiotoxicity.

    Cannabidiol CBD is a nonpsychotropic constituent of marijuana, which is well tolerated in humans, with antioxidant, antiinflammatory and recently discovered antitumor properties. DOX-induced cardiomyopathy was characterized by increased myocardial injury elevated serum creatine kinase and lactate dehydrogenase levels , myocardial oxidative and nitrative stress decreased total glutathione content and glutathione peroxidase 1 activity, increased lipid peroxidation, 3-nitrotyrosine formation and expression of inducible nitric oxide synthase mRNA , myocardial cell death apoptotic and poly[ADP]-ribose polymerase 1 [PARP]-dependent and cardiac dysfunction decline in ejection fraction and left ventricular fractional shortening.

    These data suggest that CBD may represent a novel cardioprotective strategy against DOX-induced cardiotoxicity, and the above-described effects on mitochondrial function and biogenesis may. Beale, Camilla; Broyd, Samantha J. Chronic cannabis use is associated with neuroanatomical alterations in the hippocampus.

    This study examined whether prolonged administration of CBD to regular cannabis users within the community could reverse or reduce the characteristic hippocampal harms associated with chronic cannabis use. Participants were assessed at baseline and post- CBD treatment using structural magnetic resonance imaging. Automated longitudinal hippocampal segmentation was performed to assess volumetric change over the whole hippocampus and within 12 subfields.

    No change was observed in left or right hippocampus as a whole. Heavy cannabis users demonstrated marked growth in the left subicular complex, predominantly within the presubiculum, and right cornu ammonis CA 1 compared to lighter users.

    Associations between greater right subicular complex and total hippocampal volume and higher plasma CBD concentration were evident, particularly in heavy users. Our findings suggest a restorative effect of CBD on the subicular and CA1 subfields in current cannabis users, especially those with greater lifetime exposure to cannabis.

    While replication is required in a larger, placebo-controlled trial, these findings support a protective role of CBD against. Relevance to Alzheimer's Disease. Microglial activation is an invariant feature of Alzheimer's disease AD. On the other hand, the phytocannabinoid cannabidiol CBD has shown anti-inflammatory properties in different paradigms.

    In contrast, 4-[4- 1,1-dimethylheptyl -2,6-dimethoxyphenyl]-6,6-dimethyl-bicyclo[3. All of the cannabinoids decreased lipopolysaccharide-induced nitrite generation, which was insensitive to cannabinoid antagonism. In summary, CBD is able to modulate microglial cell function in vitro and induce beneficial effects in an in vivo model of AD.

    Given that CBD lacks psychoactivity, it may represent a novel therapeutic approach for this neurological disease. The immunosuppressive activity of cannabinoids has been well established. However, the underlying mechanisms are largely unknown.

    To view the other articles in this section visit http: Safety and side effects of cannabidiol , a Cannabis sativa constituent.

    Cannabidiol CBD , a major nonpsychotropic constituent of Cannabis, has multiple pharmacological actions, including anxiolytic, antipsychotic, antiemetic and anti-inflammatory properties. However, little is known about its safety and side effect profile in animals and humans.

    This review describes in vivo and in vitro reports of CBD administration across a wide range of concentrations, based on reports retrieved from Web of Science, Scielo and Medline. The keywords searched were "cannabinoids", " cannabidiol " and "side effects". Several studies suggest that CBD is non-toxic in non-transformed cells and does not induce changes on food intake, does not induce catalepsy, does not affect physiological parameters heart rate, blood pressure and body temperature , does not affect gastrointestinal transit and does not alter psychomotor or psychological functions.

    Conversely, some studies reported that this cannabinoid can induce some side effects, including inhibition of hepatic drug metabolism, alterations of in vitro cell viability, decreased fertilization capacity, and decreased activities of p-glycoprotein and other drug transporters.

    Based on recent advances in cannabinoid administration in humans, controlled CBD may be safe in humans and animals. However, further studies are needed to clarify these reported in vitro and in vivo side effects.

    Cannabidiol CBD is a major Cannabis sativa constituent, which does not cause the typical marijuana psychoactivity. However, it has been shown to be active in a numerous pharmacological assays, including mice tests for anxiety, obsessive-compulsive disorder, depression and schizophrenia.

    In human trials the doses of CBD needed to achieve effects in anxiety and schizophrenia are high. We report now the synthesis of 3 fluorinated CBD derivatives, one of which, 4'-F- CBD HUF 1 , is considerably more potent than CBD in behavioral assays in mice predictive of anxiolytic, antidepressant, antipsychotic and anti-compulsive activity.

    Inhibition of aldose reductase activity by Cannabis sativa chemotypes extracts with high content of cannabidiol or cannabigerol. Aldose reductase ALR2 is a key enzyme involved in diabetic complications and the search for new aldose reductase inhibitors ARIs is currently very important. The synthetic ARIs are often associated with deleterious side effects and medicinal and edible plants, containing compounds with aldose reductase inhibitory activity, could be useful for prevention and therapy of diabetic complications.

    Non-psychotropic phytocannabinoids exert multiple pharmacological effects with therapeutic potential in many diseases such as inflammation, cancer, diabetes. Here, we have investigated the inhibitory effects of extracts and their fractions from two Cannabis sativa L. A molecular docking study was performed to evaluate the interaction of these cannabinoids with the active site of ALR2 compared to known ARIs.

    The inhibitory activity of the fractions was greater for acidic cannabinoid-rich fractions. Comparative molecular docking results have shown a higher stability of the ALR2-cannabinoid acids complex than the other inhibitors. These results may have some relevance for the possible use of C. Accumulating evidence suggests that cannabidiol CBD may be an effective and safe anxiolytic agent and potentially also an antidepressant.

    The objective of this study was to further examine these properties of CBD using the 'depressive-like' Wistar-Kyoto WKY rat, focusing on the drug's effect on anhedonia-like behaviors. These findings extend the limited knowledge on the antidepressant effect of CBD , now shown for the first time in a genetic animal model of depression.

    These results suggest that CBD may be beneficial for the treatment of clinical depression and other states with prominent anhedonia. Cannabidiol in humans-the quest for therapeutic targets. Cannabidiol CBD , a major phytocannabinoid constituent of cannabis, is attracting growing attention in medicine for its anxiolytic, antipsychotic, antiemetic and anti-inflammatory properties. However, up to this point, a comprehensive literature review of the effects of CBD in humans is lacking.

    The aim of the present systematic review is to examine the randomized and crossover studies that administered CBD to healthy controls and to clinical patients. Both monotherapy and combination studies e. A total of 34 studies were identified: Potential pharmacokinetic and pharmacodynamic explanations for these results are discussed.

    Cannabidiol -induced apoptosis in primary lymphocytes is associated with oxidative stress-dependent activation of caspase We recently reported that cannabidiol CBD exhibited a generalized suppressive effect on T-cell functional activities in splenocytes directly exposed to CBD in vitro or isolated from CBD -administered mice.

    To investigate the potential mechanisms of CBD effects on T cells, we characterized the pro-apoptotic effect of CBD on primary lymphocytes. The apoptosis of splenocytes was markedly enhanced following CBD exposure in a time- and concentration-dependent manner, as evidenced by nuclear hypodiploidity and DNA strand breaks. Pretreatment of splenocytes with a cell-permeable inhibitor for caspase-8 significantly attenuated, in a concentration-dependent manner, CBD -mediated apoptosis, but not ROS production.

    Collectively, the present study demonstrated that the apoptotic effect of CBD in primary lymphocytes is closely associated with oxidative stress-dependent activation of caspase CBD is a constituent of some strains of recreational cannabis but its content is highly variable. This study was undertaken to determine if CBD could reverse hypothermia or hypolocomotor effects caused by THC in rats.

    Additional experiments determined the effects of pretreatment with the cannabinoid CB1 receptor antagonist SR rimonabant. CBD did not attentuate THC-induced hypothermia or hypolocomotion but instead exaggerated these effects in some conditions. There is no evidence from this study that elevated CBD content in cannabis could provide protection from the physiological effects of THC, in rats. Pharmacological properties of cannabidiol in the treatment of psychiatric disorders: Cannabidiol CBD represents a new promising drug due to a wide spectrum of pharmacological actions.

    In order to relate CBD clinical efficacy to its pharmacological mechanisms of action, we performed a bibliographic search on PUBMED about all clinical studies investigating the use of CBD as a treatment of psychiatric symptoms.

    In conclusion, current evidences suggest that CBD has the ability to reduce psychotic, anxiety and withdrawal symptoms by means of several hypothesised pharmacological properties. However, further studies should include larger randomised controlled samples and investigate the impact of CBD on biological measures in order to correlate CBD 's clinical effects to potential modifications of neurotransmitters signalling and structural and functional cerebral changes.

    Cannabidiol as potential treatment in refractory pediatric epilepsy. In recent years there has been great scientific and public interest focused on the therapeutic potential of compounds derived from cannabis for the treatment of refractory epilepsy in children.

    From in vitro and in vivo studies on animal models, cannabidiol CBD appears to be a promising anticonvulsant drug with a favorable side-effect profile. In humans, CBD efficacy and safety is not supported by well-designed trials and its use has been described by anecdotal reports. It will be necessary to investigate CBD safety, pharmacokinetics and interaction with other anti-epileptic drugs AEDs alongside performing double-blinded placebo-controlled trials in order to obtain conclusive data on its efficacy and safety in children.

    Does cannabidiol have a role in the treatment of schizophrenia? Schizophrenia is a debilitating psychiatric disorder which places a significant emotional and economic strain on the individual and society-at-large. Unfortunately, currently available therapeutic strategies do not provide adequate relief and some patients are treatment-resistant.

    In this regard, cannabidiol CBD , a non-psychoactive constituent of Cannabis sativa, has shown significant promise as a potential antipsychotic for the treatment of schizophrenia. However, there is still considerable uncertainty about the mechanism of action of CBD as well as the brain regions which are thought to mediate its putative antipsychotic effects.

    We argue that further research on CBD is required to fast-track its progress to the clinic and in doing so, we may generate novel insights into the neurobiology of schizophrenia. Cannabidiol normalizes caspase 3, synaptophysin, and mitochondrial fission protein DNM1L expression levels in rats with brain iron overload: We have recently shown that chronic treatment with cannabidiol CBD was able to recover memory deficits induced by brain iron loading in a dose-dependent manner in rats.

    Brain iron accumulation is implicated in the pathogenesis of neurodegenerative diseases, including Parkinson's and Alzheimer's, and has been related to cognitive deficits in animals and human subjects. Deficits in synaptic energy supply have been linked to neurodegenerative diseases, evidencing the key role played by mitochondria in maintaining viable neural cells and functional circuits.

    The 2,4,6-trinitrobenzene sulphonic acid TNBS model of acute colitis in rats was used to assess damage, inflammation myeloperoxidase activity and in vitro colonic motility. Sulphasalazine was used as an active control drug. Sulphasalazine, THC and CBD proved beneficial in this model of colitis with the dose-response relationship for the phytocannabinoids showing a bell-shaped pattern on the majority of parameters optimal THC and CBD dose, 10 mg.

    THC was the most effective drug. The effects of these phytocannabinoids were additive, and CBD increased some effects of an ineffective THC dose to the level of an effective one. In this model of colitis, THC and CBD not only reduced inflammation but also lowered the occurrence of functional disturbances. Subjective and physiological effects after controlled Sativex and oral THC administration.

    Sativex is a cannabis-plant extract delivering nearly 1: In this study, pharmacodynamic effects were compared over Oral THC and Sativex produced similar, clinically insignificant increases in heart rate, anxiety, and "good drug effects" with no serious adverse events.

    Oral and oromucosal THC have slower absorption, lower rate of THC delivery to the brain, and fewer associated adverse events as compared with smoked cannabis. These results indicate that Sativex has a pharmacodynamic safety profile comparable to that of oral THC at low, therapeutic doses. The plant Cannabis sativa, commonly called cannabis or marijuana, has been used for its psychotropic and mind-altering side effects for millennia.

    There has been growing attention in recent years on its potential therapeutic efficacy as municipalities and legislative bodies in the United States, Canada, and other countries grapple with enacting policy to facilitate the use of cannabis or its constituents for medical purposes. THC is thought to produce the main psychoactive effects of cannabis, while CBD does not appear to have similar effects.

    In this article, we review the available evidence on the pharmacology and behavioral interactions of THC and CBD from preclinical and human studies, particularly with reference to anxiety and psychosis-like symptoms. Both THC and CBD , as well as other cannabinoid molecules, are currently being evaluated for medicinal purposes, separately and in combination.

    Future cannabis-related policy decisions should include consideration of scientific findings, including the individual and interactive effects of CBD and THC. In Italy, all prescriptions for THC: CBD oromucosal spray for treatment of multiple sclerosis MS spasticity are linked to the official Agenzia Italiana del Farmaco AIFA web-based registry, which tracks the effectiveness and tolerability of medications in a prospective and observational manner.

    CBD oromucosal spray collected between January and February for 1, patients from 30 large Italian specialized MS centres were compiled. Patients had a long disease history MS spasticity was evaluated using the numerical rating scale NRS. After the first month titration and trial period, Spasticity-associated symptoms such as cramps and nocturnal spasms improved in most responding patients. Mean reported doses of THC: CBD oromucosal spray 6. CBD observational projects and reaffirm the characteristics of this therapeutic option in the management of treatment-resistant MS spasticity, a frequently overlooked symptom.

    Cannabidiol in medical marijuana: Research vistas and potential opportunities. The high and increasing prevalence of medical marijuana consumption in the general population invites the need for quality evidence regarding its safety and efficacy.

    Herein, we synthesize extant literature pertaining to the phytocannabinoid cannabidiol CBD and its brain effects. The effect of CBD on brain systems as well as on phenomenological measures e. Cannabidiol is without euphoriant properties, and exerts antipsychotic, anxiolytic, anti-seizure, as well as anti-inflammatory properties.

    It is essential to parcellate phytocannabinoids into their constituent moieties as the most abundant cannabinoid have differential effects on physiologic systems in psychopathology measures. Interventional studies with purified CBD are warranted with a call to target-engagement proof-of-principle studies using the research domain criteria RDoC framework. Abstract Cannabidiol CBD , a major cannabinoid of hemp, does not bind to CB1 receptors and is therefore devoid of psychotomimetic properties.

    It has been argued that this may occur also after oral administration in humans. However, the experimental conversion of CBD to THC and delta8- THC in simulated gastric fluid SGF is a highly artificial approach that deviates significantly from physiological conditions in the stomach; therefore, SGF does not allow an extrapolation to in vivo conditions. In addition, the typical spectrum of side effects of THC , or of the very similar synthetic cannabinoid nabilone, as listed in the official Summary of Product Characteristics e.

    Cannabidiol CBD , a major cannabinoid of hemp, does not bind to CB1 receptors and is therefore devoid of psychotomimetic properties. Six hours after the final dose on Day 5, the animals were euthanized, and samples of gastrointestinal GI tract contents were obtained.

    Lower limits of quantification: Findings of the present study show that orally dosed CBD , yielding clinically relevant plasma exposures, does not convert to THC in the minipig, a species predictive of human GI tract function.

    Performance of schizophrenic patients in the Stroop Color Word Test and electrodermal responsiveness after acute administration of cannabidiol CBD. The last decade has seen increasing evidence of dysfunctions in the endogenous cannabinoid system in schizophrenia and of its relationship with the typical cognitive impairment of the disorder.

    Studies in animal models, healthy volunteers, and psychotic patients clearly suggest an antipsychotic-like effect of cannabidiol. This study investigated the effects of cannabidiol on selective attention in 28 schizophrenic patients using the Stroop Color Word Test and on these patients' electrodermal responsiveness to auditive stimuli. The subjects attended two experimental sessions, the first one without the administration of drugs.

    In the second session the subjects were divided into three groups that received either a single dose of cannabidiol mg or cannabidiol mg or placebo. The three groups did not differ significantly with respect to electrodermal measures in the two experimental sessions.

    When the first and second sessions were compared improved performance was found in all three groups, with patients who received placebo and cannabidiol mg performing better than those who received cannabidiol mg.

    The single, acute administration of cannabidiol seems to have no beneficial effects on the performance of schizophrenic patients in the Stroop Color Word Test, although the hypothesis that chronic administration may lead to improvement cannot be disregarded. In the past five years, an increasing number of publications have focused on the discovery of the anti-inflammatory, anti-oxidant, and neuroprotective effects of CBD.

    In particular, CBD exerts positive pharmacological effects in ischemic stroke and other chronic diseases, including Parkinson's disease, Alzheimer's disease, and rheumatoid arthritis. Importantly, CBD use does not lead to tolerance. In this review, we will discuss the therapeutic possibility of CBD as a cerebroprotective agent, highlighting recent pharmacological advances, novel mechanisms, and therapeutic time window of CBD in ischemic stroke.

    Cannabis contains the psychoactive component delta9-tetrahydrocannabinol delta9- THC , and the non-psychoactive components cannabidiol CBD , cannabinol, and cannabigerol. It is well-known that delta9- THC and other cannabinoid CB1 receptor agonists are neuroprotective during global and focal ischemic injury.

    Additionally, delta9- THC also mediates psychological effects through the activation of the CB1 receptor in the central nervous system. In addition to the CB1 receptor agonists, cannabis also contains therapeutically active components which are CB1 receptor independent. The cerebroprotective action of CBD is CB1 receptor-independent, long-lasting, and has potent anti-oxidant activity.

    The main active substance, THC , acts as a partial agonist at human cannabinoid receptors CB1 and CB2 , and thus, may modulate the effects of excitatory glutamate and inhibitory gamma-aminobutyric acid neurotransmitters.

    Dizziness and fatigue were reported most frequently during the first 4 weeks of treatment and resolved within a few days even with continued treatment. Phytocannabinoids are useful therapeutics for multiple applications including treatments of constipation, malaria, rheumatism, alleviation of intraocular pressure, emesis, anxiety and some neurological and neurodegenerative disorders.

    Consistent with these medicinal properties, extracted cannabinoids have recently gained much interest in research, and some are currently in advanced stages of clinical testing.

    Other constituents of Cannabis sativa, the hemp plant, however, remain relatively unexplored in vivo. We here determined pharmacokinetic profiles of the above phytocannabinoids after acute single-dose intraperitoneal and oral administration in mice and rats.

    All phytocannabinoids readily penetrated the blood-brain barrier and solutol, despite producing moderate behavioural anomalies, led to higher brain penetration than cremophor after oral, but not intraperitoneal exposure. In mice, cremophor-based intraperitoneal administration always attained higher plasma and brain concentrations, independent of substance given.

    CBD inhibited obsessive-compulsive behaviour in a time-dependent manner matching its pharmacokinetic profile. These data provide important information on the brain and plasma exposure of new phytocannabinoids and guidance for the most efficacious administration route and time points for determination of drug effects under in vivo conditions.

    For acute nausea, the potential of cannabinoid pretreatment s to reduce LiCl-induced nausea paired with saccharin was evaluated in a subsequent drug free taste reactivity test, followed by a taste avoidance test.

    For anticipatory nausea, the potential of the cannabinoid pretreatment s to reduce the expression of LiCl-induced contextually elicited conditioned gaping was evaluated. Combined subthreshold doses of THC 0. Higher doses of THC 1. On the other hand, combined subthreshold doses of THC 0. However, higher doses of THC 1.

    Combined subthreshold doses of THC: CBDA are particularly effective as a treatment for acute nausea. Diminished gray matter in the hippocampus of cannabis users: Chronic cannabis use has been associated with memory deficits and a volume reduction of the hippocampus, but none of the studies accounted for different effects of tetrahydrocannabinol THC and cannabidiol CBD.

    Using a voxel based morphometry approach optimized for small subcortical structures DARTEL gray matter GM concentration and volume of the hippocampus were measured in 11 chronic recreational cannabis users and 13 healthy controls, and correlated with THC and CBD from hair analyses. GM volume was calculated by modulating VBM using Jacobian determinants derived from the spatial normalization.

    Lower volume in the right hippocampus in chronic cannabis users was corroborated. This confirms existing preclinical and clinical results. As a possible mechanism the influence of cannabinoids on hippocampal neurogenesis is suggested. States and the federal government are under growing pressure to legalize the use of cannabis products for medical purposes in the United States.

    In most of these states, the intent is for use in refractory epileptic seizures in children, but in a few states, the indications are broader. This review provides an overview of the pharmacology and toxicology of CBD ; summarizes some of the regulatory, safety, and cultural issues relevant to the further exploitation of its antiepileptic or other pharmacologic activities; and assesses the current status and prospects for clinical development of CBD and CBD -rich preparations for medical use in the United States.

    CBD exhibits neuroprotective, antiepileptic, anxiolytic, antipsychotic, and antiinflammatory properties. Food and Drug Administration in the United States. CBD is currently being studied in several clinical trials and is at different stages of clinical development for various medical indications. Judging from clinical findings reported so far, CBD and CBD -enriched preparations have great potential utility, but uncertainties regarding sourcing, long-term safety, abuse potential, and regulatory dilemmas remain.

    Cannabidiol in humans-the quest for therapeutic targets. Cannabidiol CBD , a major phytocannabinoid constituent of cannabis, is attracting growing attention in medicine for its anxiolytic, antipsychotic, antiemetic and anti-inflammatory properties. However, up to this point, a comprehensive literature review of the effects of CBD in humans is lacking. The aim of the present systematic review is to examine the randomized and crossover studies that administered CBD to healthy controls and to clinical patients.

    Both monotherapy and combination studies e. A total of 34 studies were identified: Potential pharmacokinetic and pharmacodynamic explanations for these results are discussed. Pharmacology and potential therapeutic role in epilepsy and other neuropsychiatric disorders. Objective To present a summary of current scientific evidence about the cannabinoid, cannabidiol CBD with regards to their relevance to epilepsy and other selected neuropsychiatric disorders.

    Methods We summarize the presentations from a conference in which invited participants reviewed relevant aspects of the physiology, mechanisms of action, pharmacology and data from studies with animal models and human subjects.

    Results Cannabis has been used to treat disease since ancient times. CBD is anticonvulsant in many acute animal models but there is limited data in chronic models.

    CBD has neuroprotective and anti-inflammatory effects. CBD appears to be well tolerated in humans but small and methodologically limited studies of CBD in human epilepsy have been inconclusive.

    More recent anecdotal reports of high-ratio CBD: Significance CBD bears investigation in epilepsy and other neuropsychiatric disorders, including anxiety, schizophrenia, addiction and neonatal hypoxic-ischemic encephalopathy. However, we lack data from well-powered double-blind randomized, controlled studies on the efficacy of pure CBD for any disorder. Initial dose-tolerability and double-blind randomized, controlled studies focusing on target intractable epilepsy populations such as patients with.

    A Model of Multiple Sclerosis. This study investigated the antispasticity potential of Sativex in mice. Chronic relapsing experimental allergic encephalomyelitis was induced in adult ABH mice resulting in hind limb spasticity development. Vehicle alone caused no significant change in spasticity. Sativex has the potential to reduce spasticity in an experimental mouse model of multiple sclerosis MS. Baclofen reduced spasticity and served as a positive control. The purpose of this study was to evaluate the potential of oral combined cannabis constituents to reduce nausea.

    The potential of intragastric i. For acute nausea, i. For anticipatory nausea, combined subthreshold i. THC alone was equally effective by intraperitoneal i. This short communication examines the question whether the experimental data presented in a study by Merrick et al.

    They concluded that "the acidic environment during normal gastrointestinal transit can expose orally CBD -treated patients to levels of THC and other psychoactive cannabinoids that may exceed the threshold for a positive physiological response. Cannabis, cannabidiol , and epilepsy--from receptors to clinical response. Recreational cannabis use in adults with epilepsy is widespread. The use of cannabis for medicinal purposes is also becoming more prevalent.

    For this purpose, various preparations of cannabis of varying strengths and content are being used. The recent changes in the legal environment have improved the availability of products with high cannabidiol CBD and low tetrahydrocannabinol THC concentrations.

    There is some anecdotal evidence of their potential efficacy, but the mechanisms of such action are not entirely clear. The mechanism of action of CBD is less clear but is likely polypharmacological. The scientific data support the role of the endocannabinoid system in seizure generation, maintenance, and control in animal models of epilepsy. There are clear data for the negative effects of cannabis on the developing and mature brain though these effects appear to be relatively mild in most cases.

    Impact of enzymatic and alkaline hydrolysis on CBD concentration in urine. A sensitive and specific analytical method for cannabidiol CBD in urine was needed to define urinary CBD pharmacokinetics after controlled CBD administration, and to confirm compliance with CBD medications including Sativex-a cannabis plant extract containing 1: Non-psychoactive CBD has a wide range of therapeutic applications and may also influence psychotropic smoked cannabis effects.

    Solid-phase extraction isolated and concentrated analytes prior to GC-MS. Enzyme-hydrolyzed urine specimens exhibited more than a fold CBD concentration increase compared to alkaline and non-hydrolyzed specimens.

    This method can be applied for urinary CBD quantification and further pharmacokinetics characterization following controlled CBD administration. A sensitive and specific analytical method for cannabidiol CBD in urine was needed to define urinary CBD pharmacokinetics after controlled CBD administration, and to confirm compliance with CBD medications including Sativex—a cannabis plant extract containing 1: Self-selection in such studies means it is impossible to rule out additional variables which may determine both cannabis strain selection and basal cognitive performance level.

    Controlled laboratory studies can better determine a direct relationship. Subjects were challenged with THC 0. CBD did not significantly reverse THC -induced impairment of a progressive ratio or a rotating turntable task. The addition of CBD to THC -containing therapeutic products may therefore help to ameliorate unwanted cognitive side-effects.

    To view this commentary visit http: In this study, adult male rhesus monkeys were assessed on visuospatial Paired Associates Learning and Self-Ordered Spatial Search memory tasks, as well as additional tests of motivation and manual dexterity. This study provides direct evidence that CBD can oppose the cognitive-impairing effects of THC and that it does so in a task-selective manner when administered simultaneously in a 1: This article is commented on by Mechoulam and Parker, pp of this issue.

    The yin and yang of cannabis-induced psychosis: The link between cannabis and psychosis has often been debated with polarized views on the topic. There is substantial epidemiological evidence showing that cannabis increases the risk of psychosis, whereas other research suggests that schizophrenia patients self-medicate with the substance.

    In the present review we will first focus on how traditional rodent models of schizophrenia have been used to improve our understanding of the propsychotic actions of THC and the antipsychotic actions of CBD.

    We will also review novel rodent models used to address genetic vulnerability to cannabis-induced schizophrenia and show that specific genes are being uncovered that modulate cannabinoid action e. Acute effects of deltatetrahydrocannabinol, cannabidiol and their combination on facial emotion recognition: Another main constituent of cannabis, cannabidiol CBD , has seemingly opposite functional effects on the brain.

    This study aimed to determine the effects of THC and CBD , both alone and in combination on emotional facial affect recognition. A visual analogue scale VAS of feeling 'stoned' was also completed.

    CBD did not influence feelings of 'stoned'. No effects of frequency of use or schizotypy were found. This is the first human study examining the effects of different cannabinoids on emotional processing. It provides preliminary evidence that different pharmacological agents acting upon the endocannabinoid system can both improve and impair recognition of emotional faces. Published by Elsevier B. A randomised, double-blind, placebo-controlled study in cannabis users. Hindocha, Chandni; Freeman, Tom P.

    Cannabis contains over 70 unique compounds and its abuse is linked to an increased risk of developing schizophrenia. The behavioural profiles of the psychotropic cannabis constituent Delta9-tetrahydrocannabinol Delta9- THC and the non-psychotomimetic constituent cannabidiol CBD were investigated with a battery of behavioural tests relevant to anxiety and positive, negative and cognitive symptoms of schizophrenia.

    Delta9- THC produced the classic cannabinoid CB1 receptor-mediated tetrad of hypolocomotion, analgesia, catalepsy and hypothermia while CBD had modest hyperthermic effects. Prepulse inhibition was increased by acute treatment with Delta9- THC 0. Chronic Delta9- THC decreased locomotor activity before and after dexamphetamine administration suggesting functional antagonism of the locomotor stimulant effect.

    Epilepsy is the most common neurological disorder, with over 50 million people worldwide affected. Recent evidence suggests that the transient receptor potential cation channel subfamily V member 1 TRPV1 may contribute to the onset and progression of some forms of epilepsy.

    Since the two nonpsychotropic cannabinoids cannabidivarin CBDV and cannabidiol CBD exert anticonvulsant activity in vivo and produce TRPV1-mediated intracellular calcium elevation in vitro, we evaluated the effects of these two compounds on TRPV1 channel activation and desensitization and in an in vitro model of epileptiform activity.

    The prototypical TRPV1 agonist, capsaicin, produced similar, although not identical effects. In recent research, orally administered cannabidiol CBD showed a relatively high incidence of somnolence in a pediatric population. To gain a better understanding of quantitative exposure, we completed an in vitro study by evaluating the formation of psychoactive cannabinoids when CBD is exposed to simulated gastric fluid SGF. Linearity was demonstrated for each component over the concentration range used in this study.

    Samples were analyzed using chromatography with UV and mass spectrometry detection. The first-order kinetics observed in this study allowed estimated levels to be calculated and indicated that the acidic environment during normal gastrointestinal transit can expose orally CBD -treated patients to levels of THC and other psychoactive cannabinoids that may exceed the threshold for a physiological response.

    Delivery methods that decrease the potential for. The treatment of glioblastoma cells with both compounds led to significant modulations of the cell cycle and induction of reactive oxygen species ROS and apoptosis as well as specific modulations of extracellular signal-regulated kinase ERK and caspase activities. These specific changes were not observed with either compound individually, indicating that the signal transduction pathways affected by the combination treatment were unique.

    Cannabis is commonly used by humans to relieve stress. Here, we evaluate the potential of intraperitoneally i. This was an observational, prospective, multicentre, non-interventional study. CBD oromucosal spray according to approved labelling, were followed for 3 months. The main endpoints were the evolution of MSS and associated symptoms, quality of life QoL and tolerability. The mean duration of MSS was 7.

    Three hundred and forty nine participants continued with THC: CBD oromucosal spray after 1 month, and after 3 months. MSS scores and spasticity-related symptoms spasms, fatigue, pain, sleep quality and bladder dysfunction were significantly improved by THC: Adverse events, none of which were severe or serious, were reported by In everyday clinical practice, THC: A systematic review of the antipsychotic properties of cannabidiol in humans.

    Despite extensive study over the past decades, available treatments for schizophrenia are only modestly effective and cause serious metabolic and neurological side effects.

    Therefore, there is an urgent need for novel therapeutic targets for the treatment of schizophrenia. A highly promising new pharmacological target in the context of schizophrenia is the endocannabinoid system. However, the non-psychotropic, plant-derived cannabinoid agent cannabidiol CBD may have antipsychotic properties, and thus may be a promising new agent in the treatment of schizophrenia.

    Here we review studies that investigated the antipsychotic properties of CBD in human subjects. Results show the ability of CBD to counteract psychotic symptoms and cognitive impairment associated with cannabis use as well as with acute THC administration.

    In addition, CBD may lower the risk for developing psychosis that is related to cannabis use. These effects are possibly mediated by opposite effects of CBD and THC on brain activity patterns in key regions implicated in the pathophysiology of schizophrenia, such as the striatum, hippocampus and prefrontal cortex.

    The first small-scale clinical studies with CBD treatment of patients with psychotic symptoms further confirm the potential of CBD as an effective, safe and well-tolerated antipsychotic compound, although large randomised clinical trials will be needed before this novel therapy can be introduced into clinical practice. Beyond the CB1 Receptor: Is Cannabidiol the Answer for Disorders of Motivation? The Cannabis sativa plant has been used to treat various physiological and psychiatric conditions for millennia.

    Current research is focused on isolating potentially therapeutic chemical constituents from the plant for use in the treatment of many central nervous system disorders. Of particular interest is the primary nonpsychoactive constituent cannabidiol CBD. Here we review preclinical and clinical data outlining the therapeutic efficacy of CBD for the treatment of motivational disorders such as drug addiction, anxiety, and depression. Across studies, findings suggest promising treatment effects and potentially overlapping mechanisms of action for CBD in these disorders and indicate the need for further systematic investigation of the viability of CBD as a psychiatric pharmacotherapy.

    Cannabinoid ligands regulate bone mass, but skeletal effects of cannabis marijuana and hashish have not been reported. Bone fractures are highly prevalent, involving prolonged immobilization and discomfort.

    Here we report that the major non-psychoactive cannabis constituent, cannabidiol CBD , enhances the biomechanical properties of healing rat mid-femoral fractures. By contrast, CBD stimulated mRNA expression of Plod1 in primary osteoblast cultures, encoding an enzyme that catalyzes lysine hydroxylation, which is in turn involved in collagen crosslinking and stabilization. Using Fourier transform infrared FTIR spectroscopy we confirmed the increase in collagen crosslink ratio by CBD , which is likely to contribute to the improved biomechanical properties of the fracture callus.

    Taken together, these data show that CBD leads to improvement in fracture healing and demonstrate the critical mechanical role of collagen crosslinking enzymes. The high prevalence of adolescent cannabis use, the association between this use and later psychiatric disease, and increased access to high-potency cannabis highlight the need for a better understanding of the long-term effects of adolescent cannabis use on cognitive and behavioral outcomes.

    The current study examined the immediate and long-term behavioral consequences of THC , CBD , and their combination in a mouse model of adolescent cannabis use. Animals were then evaluated with a battery of behavioral tests 1 day after drug treatment, and again after 42 drug-free days. The tests included the following: Adolescent chronic exposure to THC increased repetitive and compulsive-like behaviors, as measured by the Nestlet shredding task.

    Chronic administration of THC , either during adolescence or during adulthood, led to a delayed increase in anxiety as measured by the EPM. However, most studies have tested only one dose of CBD in combination with one dose of oral THC , making it difficult to assess the nature of this interaction.

    Further, the effect of oral CBD on smoked cannabis administration is unknown. The behavioral and cardiovascular effects of cannabis were measured at baseline and repeatedly throughout the session. Under placebo CBD conditions, active cannabis 1 was self-administered by significantly more participants than placebo cannabis and 2 produced significant, time-dependent increases in ratings of 'High', 'Good Effect', ratings of the cannabis cigarette eg, strength, liking , and heart rate relative to inactive cannabis.

    CBD , which alone produced no significant psychoactive or cardiovascular effects, did not significantly alter any of these outcomes. Cannabis self-administration, subjective effects, and cannabis ratings did not vary as a function of CBD dose relative to placebo capsules.

    These findings suggest that oral CBD does not reduce the reinforcing, physiological, or positive subjective effects of smoked cannabis. People with multiple sclerosis may present with a wide range of disease symptoms during the evolution of the disease; among these, spasticity can have a marked impact on their well-being and quality of life.

    Symptom control, including spasticity, remains a key management strategy to improve the patient's well-being and functional status. However, available drug therapies for spasticity sometimes have limited benefit and they are often associated with poor tolerability. Sativex is a 1: Clinical experience with Sativex in patients with multiple sclerosis is accumulating steadily.

    Results from randomized, controlled trials have reported a reduction in the severity of symptoms associated with spasticity, leading to a better ability to perform daily activities and an improved perception of patients and their carers regarding functional status when Sativex was added to the current treatment regimen. Adverse events such as dizziness, diarrhea, fatigue, nausea, headache and somnolence occur quite frequently with Sativex, but they are generally of mild-to-moderate intensity and their incidence can be markedly reduced by gradual 'uptitration'.

    In summary, initial well-controlled studies with Sativex oromucosal spray administered as an add-on to usual therapy have produced promising results and highlight encouraging avenues for future research. Cannabidiol for the treatment of cannabis withdrawal syndrome: Cannabis withdrawal in heavy users is commonly followed by increased anxiety, insomnia, loss of appetite, migraine, irritability, restlessness and other physical and psychological signs.

    Tolerance to cannabis and cannabis withdrawal symptoms are believed to be the result of the desensitization of CB1 receptors by THC. Daily symptom assessments demonstrated the absence of significant withdrawal, anxiety and dissociative symptoms during the treatment.

    CBD can be effective for the treatment of cannabis withdrawal syndrome. A critical review of the antipsychotic effects of cannabidiol: Another major constituent is cannabidiol CBD , formerly regarded to be devoid of pharmacological activity. Subsequent studies have demonstrated that CBD has antipsychotic effects as observed using animal models and in healthy volunteers. Thus, this article provides a critical review of the research evaluating antipsychotic potential of this cannabinoid.

    CBD appears to have pharmacological profile similar to that of atypical antipsychotic drugs as seem using behavioral and neurochemical techniques in animal models. Additionally, CBD prevented human experimental psychosis and was effective in open case reports and clinical trials in patients with schizophrenia with a remarkable safety profile. Although the mechanisms of the antipsychotic properties are still not fully understood, we propose a hypothesis that could have a heuristic value to inspire new studies.

    These results support the idea that CBD may be a future therapeutic option in psychosis, in general and in schizophrenia, in particular. We tested the possible synergy between CBD and THC in decreasing mechanical sensitivity in a mouse model of paclitaxel-induced neuropathic pain. We also tested the effects of CBD on oxaliplatin- and vincristine-induced mechanical sensitivity. CBD also attenuated oxaliplatin- but not vincristine-induced mechanical sensitivity, while THC significantly attenuated vincristine- but not oxaliplatin-induced mechanical sensitivity.

    The low dose combination significantly attenuated oxaliplatin- but not vincristine-induced mechanical sensitivity. CBD may be potent and effective at preventing the development of chemotherapy-induced peripheral neuropathy, and its clinical use may be enhanced by co-administration of low doses of THC. These treatment strategies would increase the therapeutic window of cannabis-based pharmacotherapies.

    Cannabis use can both increase and reduce anxiety in humans. The neurophysiological substrates of these effects are unknown. To investigate the effects of 2 main psychoactive constituents of Cannabis sativa Delta9-tetrahydrocannabinol [Delta9- THC ] and cannabidiol [ CBD ] on regional brain function during emotional processing. Subjects were studied on 3 separate occasions using an event-related functional magnetic resonance imaging paradigm while viewing faces that implicitly elicited different levels of anxiety.

    Each scanning session was preceded by the ingestion of either 10 mg of Delta9- THC , mg of CBD , or a placebo in a double-blind, randomized, placebo-controlled design. Fifteen healthy, English-native, right-handed men who had used cannabis 15 times or less in their life. Regional brain activation blood oxygenation level-dependent response , electrodermal activity skin conductance response [SCR] , and objective and subjective ratings of anxiety.

    Delta9-Tetrahydrocannabinol increased anxiety, as well as levels of intoxication, sedation, and psychotic symptoms, whereas there was a trend for a reduction in anxiety following administration of CBD. Cannabidiol attenuated the blood oxygenation level-dependent signal in the amygdala and the anterior and posterior cingulate cortex while subjects were processing intensely fearful faces, and its suppression of the amygdalar and anterior cingulate responses was correlated with the concurrent reduction in SCR fluctuations.

    Delta9-Tetrahydrocannabinol mainly modulated activation in frontal and parietal areas. Delta9-Tetrahydrocannabinol and CBD had clearly distinct effects on the neural, electrodermal, and symptomatic response to fearful faces.

    The effects of CBD on activation in limbic and paralimbic regions may contribute to its ability to.
