Video in the public domain. Q. Does marijuana have any medical value? Any determination of a drug’s valid medical use must be based on the best available science undertaken by medical professionals. The Institute of Medicine conducted a comprehensive study in 1999 to assess the potential health benefits of marijuana and its constituent cannabinoids. The study concluded that smoking marijuana is not recommended for the treatment of any disease condition. In addition, there are more effective medications currently available. For those reasons, the Institute of Medicine concluded that there is little future in smoked marijuana as a medically approved medication. Advocates have promoted the use of marijuana to treat medical conditions such as glaucoma. However, this is a good example of more effective medicines already available. According to the Institute of Medicine, there are six classes of drugs and multiple surgical techniques that are available to treat glaucoma that effectively slow the progression of this disease by reducing high intraocular pressure. In other studies, smoked marijuana has been shown to cause a variety of health problems, including cancer, respiratory problems, increased heart rate, loss of motor skills, and increased heart rate. Furthermore, marijuana can affect the immune system by impairing the ability of T-cells to fight off infections, demonstrating that marijuana can do more harm than good in people with already compromised immune systems. In addition, in a recent study by the Mayo Clinic, THC was shown to be less effective than standard treatments in helping cancer patients regain lost appetites. The American Medical Association recommends that marijuana remain a Schedule I controlled substance. The DEA supports research into the safety and efficacy of THC (the major psychoactive component of marijuana), and such studies are ongoing, supported by grants from the National Institute on Drug Abuse. As a result of such research, a synthetic mirror-image molecule of the THC drug, Marinol, has been available to the public since 1985. The Food and Drug Administration has determined that Marinol is safe, effective, and has therapeutic benefits for use as a treatment for nausea and vomiting associated with cancer chemotherapy, and as a treatment of weight loss in patients with AIDS. However, it does not produce the harmful health effects associated with smoking marijuana. Furthermore, the DEA recently approved the University of California San Diego to undertake rigorous scientific studies to assess the safety and efficacy of cannabis compounds for treating certain debilitating medical conditions. Tt’s also important to realize that the campaign to allow marijuana to be used as medicine is a tactical maneuver in an overall strategy to completely legalize all drugs. Pro-legalization groups have transformed the debate from decriminalizing drug use to one of compassion and care for people with serious diseases. The New York Times interviewed Ethan Nadelman, Director of the Lindesmith Center, in January 2000. Responding to criticism from former Drug Czar Barry McCaffrey that the medical marijuana issue is a stalking-horse for drug legalization, Mr. Nadelman did not contradict General McCaffrey. “Will it help lead toward marijuana legaization?” Mr. Nadelman said: “I hope so.”
