Legalize It? Medical Marijuana Fully Explained

Yesterday Massachusetts voted to legalize medical marijuana; Arkansas voted against it. We’re not talking just munchies and Pink Floyd — weed can be a legitimate treatment for medical ailments.
Legalize It? Medical Marijuana Fully Explained

To light up or not to light up? That was the question this year, when Massachusetts voted to legalize medical marijuana and Arkansas rejected a similar initiative.

A Healthy High — Why It Matters

Medical marijuana is prescribed by physicians to alleviate symptoms of disorders ranging from anxiety to glaucoma to wasting disease. It’s already legal in 17 states (Connecticut was the most recent legalizer, in 2012) and Washington, D.C. This election season, Massachusetts voted to legalize medical marijuana while Arkansas voted against it. Medical marijuana legislation is still currently pending in Illinois, New York, Ohio, and Pennsylvania. Lawmakers will decide whether qualifying patients and healthcare professionals can purchase, carry, and use small amounts of marijuana.

Since ancient times, people have been smoking joints to cure a variety of physical and psychological ailments. As early as 2737 B.C., the Chinese Emperor Shen Neng recommended marijuana to treat gout, rheumatism, malaria, and even a faulty memory (ironic). Ancient Hindus used marijuana to beat stress and relieve pain during childbirth.

Today, medical experts still use marijuana as a treatment for a range of medical complaints. Marijuana can help ease nausea and vomiting for chemotherapy patients; stimulate appetite in people with HIV and AIDS; relieve muscle tension and spasms in people who suffer from multiple sclerosis; help treat glaucoma; relieve anxiety; and provide pain relief, especially for terminally ill patients. Some research even suggests marijuana can help delay the growth of certain types of cancer in the human body.

Indeed, marijuana is more complicated than Jay and Silent Bob would have us believe. Tetrahydrocannabinol (THC) is a cannabinoid (or class of chemical compounds) in marijuana that binds to endocannabinoid receptors in the brain and body, reducing pain (indica strains) and anxiety (sativa strains). It’s the heavier intake, particularly of the sativa strain of cannabis, that produces that high-as-a-kite feeling. But not every health expert is on board with keeping a stash of marijuana in the medicine cabinet.

Doctor’s Orders — The Answer/Debate

There’s plenty of recent research suggesting marijuana and other cannabinoids can help treat a variety of medical conditions like the ones outlined above The Therapeutic Potential of Cannabis and Cannabinoids. Grotenhermen, F., Muller-Vahl, K. Institute of Neurology, University College London, Queen Square, London, UK. Lancet Neurology 2003; 2(5):291-8. Medical Marijuana: Clearing Away the Smoke.

Medical marijuana: medical necessity versus political agenda. Clark, P.A., Capuzzi, K., Fick, C. Jesuit Community, St Joseph's University, Philadelphia, PA. Medical Science Monitor 2011;17(12): RA249-61.But other studies suggest long-term use of high doses of marijuana may have some unfavorable side effects, including lethargy, loss of balance, and even anxiety and panic attacks. There’s also the possibility that users can become dependent on marijuana and go through withdrawal when usage stops Medical Marijuana: Clearing Away the Smoke. Grant, I., Hampton Atkinson, J., Goaux, B., et al. Center for Medicinal Cannabis Research; University of California, San Diego; San Diego, CA. The Open Neurology Journal 2012;6:18-25.. Plus, long-term marijuana use has been linked to increased risk for respiratory problems Effects of Marijuana Smoking on Pulmonary Function and Respiratory Complications: A Systematic Review.

Those with cardiovascular disease and substance use disorders may also experience adverse effects and, ultimately, marijuana’s usefulness may depend on the specific individual who’s using it Medical Marijuana: Clearing Away the Smoke. Grant, I., Hampton Atkinson, J., Goaux, B., et al. Center for Medicinal Cannabis Research; University of California, San Diego; San Diego, CA. The Open Neurology Journal 2012;6:18-25..

Aside from the debate over medical marijuana’s helpfulness (or lack thereof), it’s worth noting that none of the states with pending marijuana legislation plan to let anyone travel with a truck-full of pot. Voters in most states will decide whether eligible patients can cultivate or possess fairly small amounts (a few ounces) of marijuana or obtain it from state-regulated dispensaries.

Stay tuned throughout the year for updates on the marijuana sitch; ’til the results are in, it might just be a half-baked idea.
