We’ve told you for a while now about the anti-tumoral properties of marijuana. We’ve repeatedly shown you that marijuana smoking does not lead to an increased risk of head and neck cancers. But now research is showing that marijuana smoking may actually help prevent head and neck cancers!
(Cancer Prevention Research) Cannabinoids, constituents of marijuana smoke, have been recognized to have potential antitumor properties. However, the epidemiologic evidence addressing the relationship between marijuana use and the induction of head and neck squamous cell carcinoma (HNSCC) is inconsistent and conflicting.
Cases (n = 434) were patients with incident HNSCC disease from nine medical facilities in the Greater Boston, MA area between December 1999 and December 2003. Controls (n = 547) were frequency matched to cases on age (±3 years), gender, and town of residence, randomly selected from Massachusetts town books. A questionnaire was adopted to collect information on lifetime marijuana use (decade-specific exposures) and associations evaluated using unconditional logistic regression.
After adjusting for potential confounders (including smoking and alcohol drinking), 10 to 20 years of marijuana use was associated with a significantly reduced risk of HNSCC [odds ratio (OR)10-<20 years versus never users, 0.38; 95% confidence interval (CI), 0.22-0.67]. Among marijuana users moderate weekly use was associated with reduced risk (OR0.5-<1.5 times versus <0.5 time, 0.52; 95% CI, 0.32-0.85). The magnitude of reduced risk was more pronounced for those who started use at an older age (OR15-<20 years versus never users, 0.53; 95% CI, 0.30-0.95; OR?20 years versus never users, 0.39; 95% CI, 0.17-0.90; Ptrend < 0.001). These inverse associations did not depend on human papillomavirus 16 antibody status. However, for the subjects who have the same level of smoking or alcohol drinking, we observed attenuated risk of HNSCC among those who use marijuana compared with those who do not.
Our study suggests that moderate marijuana use is associated with reduced risk of HNSCC.
I read an article called “Hypothesizing that marijuana smokers are at a significantly lower risk of carcinogenicity relative to tobacco-non-marijuana smokers: evidenced based on statistical reevaluation of current literature.” that supported the claim with a review of a 1997 study.

Is it time yet for class action lawsuits?
Surely, NORML, MPP, ACLU and LEAP have enough qualified individuals and lawyers to seek hundreds of millions of dollars in damages . . .
Population control. After all of these years, the G-men must know what the defense for cancer is, and it just could be Marijuana. Get real! Schedule I for something that opens up the creative mind and gives you a nice buzz for a couple of hours? Blah!
The G-Men didn’t seem to flinch too hard when the tobacco companies were slamming cigarettes down everyone’s throats all of those years — until it was basically too late. It doesn’t seem like they move very quickly when it comes to eliminating cancer except more medical charges for doctor and hospital visits. Their Motto: Bend over. Have to get our daily allowance of our pharmaceuticals.
No wonder why they label marijuana as a Schedule I Substance. They can’t let MJ out of the bag too quickly. What’s left for their population control program? Hmmm, let’s guess. More fast food? Toke on!
