The Evidence Is Clear – Medical Marijuana Is Real

By Paul Armentano

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.”

In 2011, the Obama administration – via the United States Drug Enforcement Administration (DEA) – formally denied a nine-year-old administrative petition filed by NORML and a coalition of public interest organizations calling on the agency to initiate hearings to reassess the present classification of marijuana as a schedule I controlled substance. In her denial of the petition, DEA administrator Michele Leonhart alleged: “[T]here are no adequate and well-controlled studies proving (marijuana’s) efficacy; the drug is not accepted by qualified experts. … At this time, the known risks of marijuana use have not been shown to be outweighed by specific benefits in well-controlled clinical trials that scientifically evaluate safety and efficacy.”

In June, Ms. Leonhart testified before Congress that she believed that heroin and marijuana posed similar threats to the public’s health because, in her opinion, “all illegal drugs are bad.”

Coalition advocates are presently appealing the DEA’s denial of their petition in federal court.

  1. Let me just say that any judge that would rule marijuana a schedule 1 substance with no medical properties should be ripped off the bench. Either he’s paid off, or too stupid to be a judge in the first place.

    I’m glad they’ve added tourette syndrome to the list. I’ve had tourette syndrome since I was a small child and was always made to take 6 or 7 pills a day with terrible side effects. When I was a teenager I found out first hand how well marijuana helped with no adverse side effects.

  3. Gilles de la Tourette syndrome
    every day Danny comes to my house to get medicated. sometimes we meet at strbx
    Danny is in a wheelchair and he has no use of legs and arms. (leon beruit syndrome) spellcheck?
    He takes pills that make him sick ,cannabis helps .
    Imagine being stuck in a wheelchair after owning a carpet cleaning co.
    He has a lot of energy , rain , cold , hot Dan comes over.
    I provide him with cannabis free of charge , it costs money to grow.

    Ca prop 215 allows cultivation of cannabis.
    when Dan was looking for someone to get stoned he would have to ask people on the street to hold the joint to his mouth (no arm use)
    They would help him ,and more than once they took his stash,his money , watch
    For the last 2 or 3 years he hasnt been robbed.
    When we have cash we go to the dispensary , luckily they are still open
    now access to MJ will limit access for patients.
    1 step forward 2 steps back
