there are no studies that prove marijuana smoke causes cnacer to those who inhale the smoke directly??...how could marijuana cause cancer??
can you cite some study??
there have been studies like that, conducted for tobacco usage...
cancer is mainly caused by smoking all the hundreds of dangerous chemicals that are pulped into the tobacco...after they mash it..
then they shred it?? and roll it up!!
it's commonsense. you put smoke in your lungs. you put something that is not suppose to be in there. you irritate them. you get cancer. it's that simple.
another thing.. people who smoke marijuana usually also smoke tobacco. it goes hand in hand. get it?..SMOKING.
so, it follows that the cancer is probably caused just as much by the tobacco as it is by the marijuana.
..going back to the studies. the main study that the pro-marijuana clan push for legalizing casual marijuana use is the one made by donald tashkin. http://www.dailysmoker.com/blog/top-anti-drug...
have you looked at a picture of the guy?..honestly, look at the guy... he looks like a marijuana smoker himself.
so tell me. would you believe anything a drug addict tells you? drug addicts will lie, steal, and cheat to get their next high. and they don't give a rat's ass about anything or anybody else.
