The War on Medicine

and the Leaves of the Tree are for the Healing of the Nations…

Although used for centuries as medicine by varied cultures across the world, in the US, medical marijuana became part of mainstream medicine in 1850, when it was added to the US Pharmacopeia. Physicians prescribed the use of cannabis broadly for a range of indications including (but not limited to) pain, emesis, migraine, insomnia, epilepsy, and opium withdrawal (Birch, 1889; Potter, 1917; Grinspoon and Bakalar, 1997; Booth, 2003).

It remained widely available until 1937, when the marijuana tax law criminalized use of the substance.  As anti-marijuana sentiments grew across the country, it was removed from the pharmacopeia in 1942 and in 1970, the passage of the Controlled Substances Act (CSA) declared marijuana a Schedule I substance and the cultivation, possession, and distribution of marijuana became prohibited.

According to the Drug Enforcement Administration (DEA), Schedule I drugs are those

“with no currently accepted medical use, no demonstrated safety profile and a high potential for abuse…[they] are the most dangerous drugs of all the drug schedules with potentially severe psychological or physical dependence” (dea.gov2; Comprehensive Drug Abuse Prevention and Control Act of 19703).

Marijuana > Heroin & Cocaine?

This classification deems marijuana more dangerous than other substances including cocaine, methamphetamine, and opiate-based drugs, which ironically are responsible for approximately 30,000 deaths per year (Centers for Disease Control and Prevention, 2015). In fact, opioid overdoses are now considered a national epidemic; the rate of opioid overdose deaths, including those related to both prescription pain relievers and heroin, has nearly quadrupled since 1999 (Centers for Disease Control and Prevention, 2015).

Given its Schedule I classification, research studies exploring both potential risks and benefits of medical marijuana have faced numerous obstacles, forcing policy to outpace science in recent years. As the national climate warms toward marijuana, research is slowly pushing forward. However, much is left to be explored before the gap between science and policy can begin to close.
