So marijuana is significantly more carcinogenic? Even if were roughly equal to tobacco’s carcinogenicity, I would expect that to be part of the public health discussion and repeated as often as the risks associated with tobacco smoking. Perhaps if marijuana was grown by large corporations then there would be more of that. Do you have any particular source or website or search terms regarding marijuana’s carcinogenic properties. My search so far ends up at NORML and related pro-legalization sites. This is one of those topics that people seem to dismiss, but I want to know the actual science on this, not the politics of it.

I’ll get back to you on it.

Here's a couple of sites which provides information regarding the harmful effects of smoking marijuana. I didn't read all the information and thus can't guarantee the answers you're looking for will be found at either site. Still, what I did read was interesting.

Health effects of Marijuana

From the article on the Health Effects of Marijuana:

"Marijuana contains more carcinogenic hydrocarbons than tobacco smoke and because marijuana smokers usually inhale deeper and hold the smoke in their lungs longer than tobacco smokers, their lungs are exposed to those carcinogenic properties longer."

"One study found that marijuana smokers were three times more likely to develop cancer of the head or neck than non-smokers. Many researchers believe than smoking marijuana is overall more harmful to the lungs than smoking tobacco."
