What has more carcinogens: marijuana or tobacco?

What has more carcinogens: marijuana or tobacco?

Tobacco: It has been intensely studied, but the lack of studies does not mean there is no risk to inhaling weed, the risk is just less well known and less well proven. The demonizing of marijuana as an 'entry drug' may be true in those susceptible, but it also has led to difficulties studying its effects, . ...Read more

Will smoking marijuana cause cancer/is it carcinogenic? If so, is it worse than smoking tobacco?

Will smoking marijuana cause cancer/is it carcinogenic? If so, is it worse than smoking tobacco?

Potentially: Unfiltered smoke contains chemicals that can promote the development of cancer, regardless of whether it is tobacco or marijuana. Putting a number on that risk is difficult because it depends what kinds of paper are used, and what additives are included when rolling these. This is just another reason to never use tobacco or marijuana. ...Read more

Is smoking marijuana less dangerous for you than smoking tobacco?

Is smoking marijuana less dangerous for you than smoking tobacco?

Both dangerous: Both are dangerous. Marijuana smoke has more carcinogens in it than regular cigarettes do, and people usually inhale and hold the smoke longer with it too. So exposure is very significant -- plus the unspecified additives and possible pesticides that no one really checks for. Alternatively, nicotine is highly addictive, and people usually smoke more regular cigarettes, more often. Neither is good. ...Read more

Does smoking marijuana  cause cancer?  I had thyroid cancer and would like to know if related.  No tobacco.  Can. It. Cause throat cancer.

Furthermore - marijuana is sometimes cut with a variety of chemicals that may be carcinogenic. I would suspect that prolonged use may be associated with throat and lung cancer, but studies are conflicting [for the docs: eur resp j feb 2008]. ...Read more

Is marijuana safer than tobacco smoke?

Depends: Any form of smoking may produce benzene derivatives, which are cacerogens. However, there are studies which estimate that cannabis smokers have less incidence of lung cancer than both cigarette smokers and non-smokers. My advice would be not to smoke, period. If you use cannabis as a legal treatment, there are other formulations available besides smoking; sativex, marinol, etc. ...Read more
