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.
