For the second time in recent months, a scientific paper published in a peer-reviewed journal has thoroughly rebutted the present Schedule I status of cannabis under US federal law, which states that the plant and its organic constituents possess a “high potential for abuse,” and that they lack “accepted medical use” and “accepted safety … under medical supervision.”

According to a just published review in the German scientific journal Deutsches Ärzteblatt International, scientific findings from over 100 controlled clinical trials involving either cannabis or its constituents provide “clear evidence that cannabinoids are useful for the treatment of various medical conditions.”

Investigators from the nova-Institute and the Hannover Medical School in Germany reviewed over 100 controlled trials assessing the safety and efficacy of cannabis and cannabinoids.

Researchers reported: “Knowledge about the therapeutic potential of cannabis products has been greatly improved by a large number of clinical trials in recent years. … There is now clear evidence that cannabinoids are useful for the treatment of various medical conditions,” including chronic neuropathy (nerve pain), multiple sclerosis, HIV/AIDS, Gilles de la Tourette syndrome, and other indications.

Regarding the safety profile of cannabis and cannabinoids, investigators determined: “The most common side effects of cannabinoids are tiredness and dizziness (in more than ten percent of patients), psychological effects, and dry mouth. Tolerance to these side effects nearly always develops within a short time. Withdrawal symptoms are hardly ever a problem in the therapeutic setting.”

Authors did express concern that cannabis could pose additional health risks for adolescents and/or pregnant or breast-feeding women, as well as individuals diagnosed with Hepatitis C, severe cardiovascular disease, addictive disorders, or those vulnerable to certain psychiatric disorders, such as schizophrenia.

Investigators acknowledged that cannabis dosing may adversely impact psychomotor skills. However, they noted, “Patients who take cannabinoids at a constant dosage over an extensive period of time often develop tolerance to the impairment of psychomotor performance, so that they can drive vehicles safely.”

They concluded, “No acute deaths have been described that could be unequivocally attributed solely to cannabis consumption or treatment with cannabinoids.”

This most recent paper follows the publication of a similar review, published in May in The Open Neurology Journal. In that paper, investigators with the University of California at San Diego and the University of California, Davis concluded: “Evidence is accumulating that cannabinoids may be useful medicine for certain indications. Based on evidence currently available, the (federal) Schedule I classification (of cannabis) is not tenable; it is not accurate that cannabis has no medical value, or that information on safety is lacking.”
