The Benefits Of Marijuana

It's 4/20 Today, And The DEA's Stance On Marijuana Still Makes No Sense

It's 4/20 today, and advocates of marijuana consumption have a lot to celebrate. With states like Washington and Colorado having led the charge of legalization, and D.C. and Oregon following suit, it's likely that other states will follow.

It's still a contentious issue for some people though (like Nancy Grace), who maintain that marijuana has no place in civilized society and the last thing we should be doing is making it legal and more accessible.

Few things illustrate the controversy better than a comparison of the web pages that purport to separate myth from fact published by the Drug Enforcement Administration (DEA) and the Drug Policy Alliance (DPA). They are almost mirror images of one another, addressing the very same points, but drawing on different studies to reach their preferred conclusions. It's stunning to see how differently these agencies can interpret the same information.

There is a single salvation from this cherry-picking point-counterpoint: the seminal report "Marijuana and Medicine: Assessing the Science Base." This comprehensive summary of marijuana was written in 1999 by the most highly regarded nongovernmental medical organization in the country, the Institute of Medicine, and it serves as the primary source for the information in this article concerning the risks and benefits of marijuana.

Health Risk Myths & Realities

The essential questions are whether the active ingredient in marijuana, a cannabinoid (chemical compound) known as THC, has any medicinal value; whether the risks associated with its use outweigh the benefits; and whether THC answers a need not currently met by any other medications on the market. In the course of that debate, several health risks are often cited:

Marijuana overdose

There is no existing evidence of anyone dying of a marijuana overdose, but this doesn't preclude the possibility of experiencing adverse or unpleasant effects when it is consumed in large amounts. For comparison's sake, alcohol overdoses claim approximately 5,000 casualties per year.This is often cited as a reason that marijuana is safer than other drugs, like alcohol.

Memory

Marijuana does impair short-term memory, but only during intoxication. THC has been shown to have a negative effect on memory, and chronic abuse of marijuana will cause permanent impairment.

Addiction

The DEA's general opposition to marijuana is comprised of 1) that whatever medical value it has is already fulfilled by other, equally effective drugs on the market, and 2) that marijuana is highly addictive.

Both points can be turned upside down: There is already an abundance of drugs that do the same job as products already on the market, and they receive approval anyway. This seems to run contrary to the DEA's first argument. And even a cursory look at many of the Schedule II opiates and amphetamines shows that high addiction potential is not a basis for legal classification of drugs. The point is that marijuana is not physically addictive, and even if it was, the DEA would appear to be quite hypocritical arguing this point.

The immune system

If smoked marijuana were to inhibit the activity of T-lymphocytes in the blood, it would compromise the body's ability to fight infection. This would put some people at the mercy of opportunistic infections and diseases, notably those who have immunosuppressive conditions like HIV or lymphoma.

However, the data does not support this. What it does support — barely — is the compromised immunity of the lungs due to the smoke from marijuana.
