Seriously, American Cancer Society, you’re publishing this Reefer Madness on your “Complementary and Alternative Medicine” data sheet in medical marijuana?
Many researchers agree that marijuana contains known carcinogens, or chemicals that can cause cancer.
All researchers agree that water contains a known explosive, hydrogen, a volatile element that can ignite with as little as a static electricity spark. That doesn’t mean water can cause explosions. Chemistry matters. Yes, cannabis smoke — all smoke — contains carcinogens. But cannabis smoke also contains THC, which has been shown to have anti-tumoral effects and inhibits cancer cell growth through apoptosis (cell “suicide”).
Results of epidemiologic studies of marijuana and cancer risk have been inconsistent, and most recent epidemiologic studies have not found a substantial effect on cancer risk. However, some researchers caution that these studies are difficult to conduct, as some people may not be truthful about illegal habits such as smoking marijuana, and that these negative results should not be interpreted as convincing evidence of safety.
Uh… what? We do studies that can’t distinguish an increased risk of cancer from pot smoking, but folks lie about pot, so we can’t trust the studies? Well, that would mean the either the people who don’t get cancer are lying about smoking pot, or people who do get cancer are lying about not smoking pot. The former doesn’t make much sense, so the author must assume there are a whole bunch of pot smokers in cancer wards who are lying about it and blaming it on something else.
Seems quite a stretch to me, especially when Dr. Tashkin studied thousands of pot smokers for 30 years, concluding “We hypothesized that there would be a positive association between marijuana use and lung cancer, and that the association would be more positive with heavier use. What we found instead was no association at all, and even a suggestion of some protective effect.”
They caution that smoking marijuana may decrease reproductive function,…
Willie Nelson has seven kids. Snoop Dogg has three kids. Tommy Chong has five kids. Bob Marley has eleven kids. Just sayin’ those reproductive scares have been studied, too, and they’re bunk.
