Mental Marijuana

Can reefers cure madness? There is some evidence that cannabis - or 'green Prozac' - has potential in the treatment of some psychiatric disorders, principally depression and bipolar disorder.

Smoking marijuana, the federal government constantly reminds us, is dangerous in every way. It impairs cognitive functioning, makes you high, and, because it's smoked, is a demon in a bong hit - and so on.

A counterargument is that pot has helped thousands of cancer and AIDS patients, for example, contend with side effects of their illnesses and treatments. There is also evidence that marijuana works for some psychiatric disorders as well, principally depression and bipolar disorder. Among some people, pot is jokingly referred to as "green Prozac."

The problem is you can't legally take a toke for psychiatric diagnoses.

"I think cannabis has a lot of potential in the treatment of mental illness," says Lester Grinspoon, emeritus professor of psychiatry at the Harvard School of Medicine. He says that it can be an effective treatment for bipolar disorder and depression. Like any medicine, he cautions, it won't work for everyone. Grinspoon has, over the last three decades, been one of the few psychiatrists willing to speak publicly on mental marijuana.

Most of the evidence to support use of pot as medicine is anecdotal; i.e., it seems to help AIDS and cancer patients contend with their diseases and handle the nausea they often experience from treatment, so there must be something to it. Many people also report that it provides a quick lift from the bowels of depression.

My own anecdotal, ahem, experience is that pot does indeed boost my mood from the badlands of depression and lower me from the Mount Everests of mania. I have no idea why or how, nor do I especially care - I'm one of those people who find Prozac and its progeny to be barely effective and with enough nasty side effects to outweigh the benefits. But I'll never tell that to the Drug Enforcement Administration or drug czar John Walters.

Instead, I'll let the Israeli army speak for me. Two weeks ago, it announced that it would provide, on an experimental basis, medical marijuana to troops suffering from post-traumatic stress disorder, another mental illness. Good enough for an army, good enough for me.

But in states with medical marijuana laws, each attempt to get depression or bipolar disorder added to the list of ailments for which the kine can be oh-so-kind has been shot down.

For example, four years ago, the Washington Medical Quality Assurance Commission was petitioned to add mental illness to its list of approved uses of medical marijuana. The commission denied the request. It argued that there was no lock-solid scientific evidence that weed worked for mental illness. The odd thing is that it had approved pot for treatment of Alzheimer's, Krohn's disease, chronic pain, and wasting syndrome based upon - you guessed it - anecdotal evidence.
