A Review of the Recent Scientific Literature, 2000 — 2012

 

Humans have cultivated and consumed the flowering tops of the female cannabis plant, colloquially known as marijuana, since virtually the beginning of recorded history. Cannabis-based textiles dating to 7,000 B.C.E have been recovered in northern China, and the plant’s use as a medicinal and mood altering agent date back nearly as far. In 2008, archeologists in Central Asia discovered over two-pounds of cannabis in the 2,700-year-old grave of an ancient shaman. After scientists conducted extensive testing on the material’s potency, they affirmed, “[T]he most probable conclusion … is that [ancient] culture[s] cultivated cannabis for pharmaceutical, psychoactive, and divinatory purposes.”

Modern cultures continue to indulge in the consumption of cannabis for these same purposes, despite a present-day, virtual worldwide ban on the plant’s cultivation and use. In the United States, federal prohibitions outlawing cannabis’ recreational, industrial, and therapeutic use were first imposed by Congress under the Marihuana Tax Act of 1937 and then later reaffirmed by federal lawmakers’ decision to classify marijuana — as well as all of the plant’s organic compounds (known as cannabinoids) — as a Schedule I substance under the Controlled Substances Act of 1970. This classification, which asserts by statute that cannabis is equally as dangerous to the public as is heroin, defines cannabis and its dozens of distinct cannabinoids as possessing ‘a high potential for abuse, … no currently accepted medical use, … [and] a lack of accepted safety for the use of the drug … under medical supervision.’ (By contrast, cocaine and methamphetamine — which remain illicit for recreational use but may be consumed under a doctor’s supervision — are classified as Schedule II drugs; examples of Schedule III and IV substances include anabolic steroids and Valium respectively, while codeine-containing analgesics are defined by a law as Schedule V drugs, the federal government’s most lenient classification.) In July 2011, the Obama Administration rebuffed an administrative inquiry seeking to reassess cannabis’ Schedule I status, and federal lawmakers continue to cite the drug’s dubious categorization as the primary rationale for the government’s ongoing criminalization of the plant and those who use it.

Nevertheless, there exists little if any scientific basis to justify the federal government’s present prohibitive stance and there is ample scientific and empirical evidence to rebut it. Despite the US government’s nearly century-long prohibition of the plant, cannabis is nonetheless one of the most investigated therapeutically active substances in history. To date, there are over 20,000 published studies or reviews in the scientific literature pertaining to the cannabis plant and its cannabinoids, nearly one-third of which were published within the last three years. This total includes over 2,700 separate papers published in 2009, 1,950 papers published in 2010, and another 2,100 published to date in 2011 (according to a keyword search on the search engine PubMed Central, the US government repository for peer-reviewed scientific research). While much of the renewed interest in cannabinoid therapeutics is a result of the discovery of the endocannabinoid regulatory system (which we describe in detail later in this booklet), some of this increased attention is also due to the growing body of testimonials from medical cannabis patients and their physicians.

The scientific conclusions of the overwhelmingly majority of modern research directly conflicts with the federal government’s stance that cannabis is a highly dangerous substance worthy of absolute criminalization.

For example, in February 2010 investigators at the University of California Center for Medicinal Cannabis Research publicly announced the findings of a series of randomized, placebo-controlled clinical trials on the medical utility of inhaled cannabis. The studies, which utilized the so-called ‘gold standard’ FDA clinical trial design, concluded that cannabis ought to be a “first line treatment” for patients with neuropathy and other serious illnesses.

Among the studies conducted by the Center, four assessed smoked marijuana’s ability to alleviate neuropathic pain, a notoriously difficult to treat type of nerve pain associated with cancer, diabetes, HIV/AIDS, spinal cord injury and many other debilitating conditions. Each of the trials found that cannabis consistently reduced patients’ pain levels to a degree that was as good or better than currently available medications.

Another study conducted by the Center’s investigators assessed the use of marijuana as a treatment for patients suffering from multiple sclerosis. That study determined that “smoked cannabis was superior to placebo in reducing spasticity and pain in patients with MS, and provided some benefit beyond currently prescribed treatments.”

Around the globe, similarly controlled trials are also taking place. A 2010 review by researchers in Germany reports that since 2005 there have been 37 controlled studies assessing the safety and efficacy of marijuana and its naturally occurring compounds in a total of 2,563 subjects. By contrast, many FDA-approved drugs go through far fewer trials involving far fewer subjects.

As clinical research into the therapeutic value of cannabinoids has proliferated so too has investigators’ understanding of cannabis’ remarkable capability to combat disease. Whereas researchers in the 1970s, 80s, and 90s primarily assessed cannabis’ ability to temporarily alleviate various disease symptoms — such as nausea associated with cancer chemotherapy — scientists today are exploring the potential role of cannabinoids to modify disease.

Of particular interest, scientists are investigating cannabinoids’ capacity to moderate autoimmune disorders such as multiple sclerosis, rheumatoid arthritis, and inflammatory bowel disease, as well as their role in the treatment of neurological disorders such as Alzheimer’s disease and amyotrophic lateral sclerosis (a.k.a. Lou Gehrig’s disease.) In fact, in 2009, the American Medical Association (AMA) resolved for the first time in the organization’s history “that cannabis’ status as a federal Schedule I controlled substance be reviewed with the goal of facilitating the conduct of clinical research and development of cannabinoid-based medicines.”

Investigators are also studying the anti-cancer activities of cannabis, as a growing body of preclinical and clinical data concludes that cannabinoids can reduce the spread of specific cancer cells via apoptosis (programmed cell death) and by the inhibition of angiogenesis (the formation of new blood vessels). Arguably, these latter findings represent far broader and more significant applications for cannabinoid therapeutics than researchers could have imagined some thirty or even twenty years ago.

THE SAFETY PROFILE OF MEDICAL CANNABIS

Cannabinoids have a remarkable safety record, particularly when compared to other therapeutically active substances. Most significantly, the consumption of marijuana — regardless of quantity or potency — cannot induce a fatal overdose. According to a 1995 review prepared for the World Health Organization, “There are no recorded cases of overdose fatalities attributed to cannabis, and the estimated lethal dose for humans extrapolated from animal studies is so high that it cannot be achieved by … users.”

In 2008, investigators at McGill University Health Centre and McGill University in Montreal and the University of British Columbia in Vancouver reviewed 23 clinical investigations of medical cannabinoid drugs (typically oral THC or liquid cannabis extracts) and eight observational studies conducted between 1966 and 2007. Investigators “did not find a higher incidence rate of serious adverse events associated with medical cannabinoid use” compared to non-using controls over these four decades.

That said, cannabis should not necessarily be viewed as a ‘harmless’ substance. Its active constituents may produce a variety of physiological and euphoric effects. As a result, there may be some populations that are susceptible to increased risks from the use of cannabis, such as adolescents, pregnant or nursing mothers, and patients who have a family history of mental illness. Patients with hepatitis C decreased lung function (such as chronic obstructive pulmonary disease), or who have a history of heart disease or stroke may also be at a greater risk of experiencing adverse side effects from marijuana. As with any medication, patients should consult thoroughly with their physician before deciding whether the medical use of cannabis is safe and appropriate.
