Cannabis Doesn't Cause Cancer, But It Might Cure It

When a NIDA funded study last May revealed no link between lung cancer and lifetime marijuana smoking, important questions were raised. We know that marijuana smoke contains carcinogenic compounds, thus NIDA's findings seemed to suggest that marijuana smoke somehow protects the user from its own inherently carcinogenic properties.

Via Forbes.com, new research offers more insight into this fascinating revelation and brings us closer to the conclusion we've long suspected: cannabis just might cure cancer.
Harvard University researchers have found that, in both laboratory and mouse studies, delta-tetrahydrocannabinol (THC) cuts tumor growth in half in common lung cancer while impeding the cancer's ability to spread.

The compound "seems to have a suppressive effect on certain lines of cancer cells," explained Dr. Len Horovitz, a pulmonary specialist at Lenox Hill Hospital in New York City.

According to the researchers, THC fights lung cancer by curbing epidermal growth factor (EGF), a molecule that promotes the growth and spread of particularly aggressive non-small cell lung cancers.
I once witnessed Andrea Barthwell get stumped at an ONDCP press conference when someone asked her to cite a reference for her claim that marijuana caused lung cancer. That was funny, but this much funnier.

Evidence that marijuana doesn't cause lung cancer has long consisted of the observation that marijuana smokers don't get cancer. But now you can google "marijuana+lung+cancer" and discover a list of excellent references refuting this old favorite of the prohibitionist camp. Heck, I can't even find it on the ONDCP's website anymore.

Still, it's generally been assumed that the failure of marijuana smokers to contract lung cancer was attributable to their reduced consumption compared to that of cigarette smokers. That THC actually suppresses cancerous cells is a far more exciting and promising explanation. This suggests, among other things, that administering THC to one's lungs though non-smoking methods just might be remarkably good for you.

With each passing year, the controversy surrounding medical marijuana becomes less of a debate and more of a referendum on the blind idiocy of the liars and quacks who've portrayed it as anything other than a miracle drug.

If marijuana proves capable of curing cancer, will these people finally shut up?
