Washington, D.C.: Marijuana smokers appear to be at a significantly lower risk of developing cancer than tobacco smokers, according to an article by Amanda Chen et al. published in the Journal of Psychoactive Drugs (Sept, 2008).

The authors analyzed existing evidence on the carcinogenicity of marijuana smoke. Although it has long been hypothesized that marijuana smoke might cause cancer because it contains tars with known carcinogenic properties, like tobacco smoke, the authors note that epidemiological studies have so far failed to show a convincing causal relation between marijuanaand smoking-related cancers.

The authors statistically re-analyzed previously published data on marijuana smoking and cancer, originally published by Dr. Stephen Sidney of Kaiser-Permante Medical Care in 1997. They looked at data on 64,833 subjects, including marijuana-only smokers, tobacco-only smokers, marijuana-and-tobacco smokers, and non-smokers, and analyzed their incidence of cancer, including lung, colorectal, prostate, breast, cervix, and tobacco-related cancers. In every case, they found a significantly lower risk of cancer for marijuana-only smokers than tobacco-only smokers.

    • "I wonder if i smoke herb and cigs...it will all even out?"
      Kinda like putting a dehumidifier and a humidifier in the same room and letting them duke it out LOL.

      I do have to say that as a long time cigarette smoker who quit 2 years ago I have never felt better. Tobacco is just nasty, addictive and I'm sure that the tobacco companies are adding more nasties to the blend. Go natural and organic and support your local Cannabis farmer...much less harmful and you'll feel so much better!!! End Prohibition now!!!

    • Guys! Guys!! Come on... tobacco and herbs/Cannabis are completely two different things ;)

      Tobacco is full of "dangerous" chemicals and we all should know that by now.

      Cannabis is all natural. I'm not surprise it can prevent cancer.

    • No shit. Tobacco is pretty much a sure fire kill with prolonged use. And there is just about no way to smoke as much weed as a smoker does tobacco. Marijuana has 2x the tar but that does not mean that it is more dangerous.
      P.S. Regardless of this information i still smoke cigarettes and not weed but its just personal preference...

    • AWESOME! and to answer your question Mojojuju, yes when everyone takes their cig breaks at work, I'm right next to them outside puffing on a doobie. I'm sure that vaporizing it is the best way, but I enjoy the act of smoking. I quit cigs about 6 months ago after seven years of two packs a day so I'm sure I'll feel that later in life but for now, it's just me and Mary...

    • I wonder if the marijuana smokers smoked an amount daily that was equivalent to the amount of tobacco the cigarette smokers consumed.

    • tobacco is a known carcinogen... even pure unadulterated tobacco (theoretically) can give mouth cancer (lets not even talk about the crap they put in cigarettes). now weed.... what's bad about weed? na-much

    • This is so true. I wish my mom would have tried it before she died of cancer. It was so taboo back then, and her generation would have it.
