If marijuana has more carcinogens than cigarettes(as most doctors say) than why is it not definitively linked to cancer like tobacco is?

Says who?: We know less than we wish we did about cannabis, and we're simply not seeing cancer wards full of stoners despite the drug having been part of life in the US for decades. Much of the scare stuff we've been told during these decades is politics. Forgive me -- anybody who claims that "most doctors say" the stuff has "more carcinogens than tobacco" is simply lying to you for their own reasons. ...Read more

Why do some doctors say marijuana can cause cancer while other doctors say no it cant? Cant we get a definitive yes or no like we did with tobacco?

Why do some doctors say marijuana can cause cancer while other doctors say no it cant? Cant we get a definitive yes or no like we did with tobacco?

No: There is no evidence that marijuana causes cancer but there is also insufficient research on marijuana - primarily due to it still being classified by the U.S. Govt as Schedule 1 which limits research on it. Therefore, those who say it does cause cancer are not basing it on any research whatsoever but there haven't been long-term trials or registeries to entirely refute that either. ...Read more

This is just another reason to never use tobacco or marijuana. ...Read more
