    mj_researchThe daily administration of CBD (cannabidiol) as an adjunctive therapy mitigates psychotic symptoms in patients with schizophrenia, according to clinical trial data published online ahead of print in The American Journal of Psychiatry.

    British researchers assessed the adjunctive use of CBD compared to placebo over a six-week period in a randomized trial of 88 schizophrenic patients. Participants ingested 1000mg of plant-derived CBD per day.

    Subjects in the CBD treatment group “had lower levels of positive psychotic symptoms and were more likely to have been rated as improved and as not severely unwell by the treating clinician” at the conclusion of the trial. CBD administration was also associated with “improvements in cognitive performance and in the level of overall functioning,” although these changes did not reach statistical significance.

    “These findings suggest that CBD has beneficial effects in patients with schizophrenia,” authors concluded. “As CBD’s effects do not appear to depend on dopamine receptor antagonism, this agent may represent a new class of treatment for the disorder.”

    Results of the prior clinical trial published in the journal Translational Psychiatry determined that CBD is superior to amisulpride, a potent anti-psychotic agent, in mitigating psychotic symptoms in schizophrenic patients.

    oil_bottlesThe use of the naturally occurring cannabinoid CBD (cannabidiol) possesses no likely abuse potential and therefore should not be subject to international drug scheduling restrictions, according to recommendations finalized today by the World Health Organization’s Expert Committee on Drug Dependence.

    Concludes WHO: “Recent evidence from animal and human studies shows that its use could have some therapeutic value for seizures due to epilepsy and related conditions. Current evidence also shows that cannabidiol is not likely to be abused or create dependence as for other cannabinoids (such as Tetra Hydro Cannabinol (THC), for instance). The ECDD therefore concluded that current information does not justify scheduling of cannabidiol and postponed a fuller review of cannabidiol preparations to May 2018, when the committee will undertake a comprehensive review of cannabis and cannabis related substances.”

    A preliminary report issued by WHO in November affirmed, “[T]here is no evidence of recreational use of CBD or any public health related problems associated with the use of pure CBD.”

    In September, NORML submitted written testimony to the US Food and Drug Administration in opposition to the imposition of new international restrictions regarding CBD access. The FDA is one of a number of agencies that advised the World Health Organization in their review.

    Despite the international health agency’s acknowledgment that CBD is therapeutic, safe, and well-tolerated, it remains classified under US law as a schedule I controlled substance.

    “The domestic classification and criminalization of cannabidiol as a schedule I controlled substance is out of step with both available science and common sense,” NORML Political Director Justin Strekal said. “It is yet another example of the US government placing ideology over evidence when it comes to issues related to the cannabis plant.”

    oil_bottlesThe use of the naturally occurring cannabinoid CBD is safe, well tolerated, and is not associated with any significant adverse public health effects, according to the findings of a preliminary report compiled by the World Health Organization’s Expert Committee on Drug Dependence.

    Authors of the report declare that CBD is “not associated with abuse potential” and that it does not induce physical dependence. “CBD is generally well tolerated with a good safety profile,” they conclude.

    Nonetheless, they acknowledge that CBD remains classified as a schedule I controlled substance under US federal law – a classification that defines it as possessing a “high potential for abuse.”

    The WHO report also comments on CBD’s therapeutic efficacy, finding that the substance has “been demonstrated as an effective treatment for epilepsy,” and that there exists “preliminary evidence that CBD may be a useful treatment for a number of other medical conditions,” including Alzheimer’s disease, cancer, Parkinson’s disease, and psychosis.

    While authors acknowledge that the “unsanctioned medical use of CBD” oils and extracts is relatively common, they affirm, “[T]here is no evidence of recreational use of CBD or any public health related problems associated with the use of pure CBD.”

    The World Health Organization is in the process of considering whether to place CBD within the agency’s international drug scheduling code. In September, NORML submitted written testimony to the US Food and Drug Administration in opposition to the enactment of new international restrictions regarding CBD access. The FDA is one of a number of agencies advising WHO in their final review.

    oil_bottlesThe US Drug Enforcement Administration has publicly reiterated its position that cannabidiol, a non-psychotropic cannabinoid, is properly categorized under federal law as a schedule I controlled substance — meaning that, by definition, it possesses “a high potential for abuse,” “no currently accepted medical use in treatment in the United States,” and lacks “accepted safety … under medical supervision.”

    The agency has long contended that CBD, along with all organic cannabinoids, is — by default — a schedule I controlled substance because it is a naturally occurring component of the cannabis plant. (This position is similarly held by both the NIDA and the FDA.) Nonetheless, a growing body of science undermines the notion that CBD meets any of the criteria necessary for such classification.

    Specifically, clinical trial data finds that CBD is “safe,” “non-toxic,” and “well tolerated” in human volunteers. Even the director of the US National Institute on Drug Abuse acknowledges that CBD is “not mind-altering” and that it “appears to be a safe drug with no addictive effects.”

    Recently conducted controlled studies also acknowledge its therapeutic efficacy, particularly the ability of CBD dosing to mitigate treatment-resistant seizures, hypertension, and psychotic symptoms in humans. Other peer-reviewed data shows that CBD therapy holds promise for the treatment of “Parkinson’s disease, Alzheimer’s disease, cerebral ischemia, diabetes, rheumatoid arthritis, other inflammatory diseases, nausea and cancer.”

    That is why in addition to the thirty states that presently recognize medical cannabis, an additional 16 states also explicitly recognize the use of CBD as a viable medical treatment.

    Nonetheless, it remains unlikely that the DEA is going to amend its position any time soon. Further, police in recent months have begun initiating raids of CBD retailers, such as those reported here, here, and here. That is why it is critical that members of Congress move forward with legislation to remove the cannabis plant from the Controlled Substances Act.

    Presently, several pieces of federal legislation are pending to amend the federal classification of CBD as a schedule I substance. These include:

    HR 2020: Passage of this act would exclude CBD from the federal definition of ‘marihuana.’

    S. 1374/HR 2920: Passage of these Acts would exempt from federal prosecution those who are engaged in state-sanctioned medical cannabis activities; it would also remove CBD from the federal definition of ‘marihuana.’

    HR 2273/S. 1008: Passage of these Acts would exclude CBD and CBD-rich cannabis plants from the federal definition of ‘marihuana.’

    oil_bottlesOral CBD administration is associated with reduced blood pressure in healthy volunteers, according to clinical trial data published online in the Journal of Clinical Investigation.

    Investigators from the University of Nottingham in the United Kingdom assessed the effects of a single oral dose of 600 mg of CBD extract versus placebo in nine male subjects.

    Cannabidiol administration reduced resting systolic blood pressure and stroke volume (the amount of blood pumped by the left ventricle of the heart in one contraction). Compared to placebo, CBD intake was associated with reduced BP levels following exercise and in response to stress. Increased heart rate was observed following CBD administration, but no “adverse events” were reported by participants either during or following the study sessions.

    Authors concluded: “Our data show that a single dose of CBD reduces resting blood pressure and the blood pressure response to stress, particularly cold stress, and especially in the post-test periods. This may reflect the anxiolytic and analgesic effects of CBD, as well as any potential direct cardiovascular effects. … Further research is also required to establish whether CBD has any role in the treatment of cardiovascular disorders such as a hypertension.”

    Full text of the study, “A single dose of cannabisiol reduces blood pressure in healthy volunteers in a randomized crossover study,” is online here.
