Haha! What on earth are you talking about? Proven that marijuana has never caused a death in history? Don't be silly.
Marijuana has carcinogens. Everyone knows that. Pretty much any kind of smoke you inhale has carcinogens. That's as basic as you can get. Everyone knows breathing in ANY kind of smoke is bad for the lungs. I can't even believe you're questioning that.
"Since marijuana is illegal, it is hard to do the controlled studies that have been done with tobacco. Because of this, it helps to look at what we do know about marijuana:
Many of the carcinogens and co-carcinogens present in tobacco smoke are also present in smoke from marijuana.
Marijuana smoking does cause inflammation and cell damage, and it has been associated with pre-cancerous changes in lung tissue.
Marijuana has been shown to cause immune system dysfunction, possibly predisposing individuals to cancer.
Bottom line: Though marijuana most likely pales in cancer risk when compared to cigarette smoking, it's better to play it safe. There are reasons in addition to lung cancer risk (and the fact that it is illegal in most states) to avoid marijuana. Marijuana likely increases the risk of testicular cancer, prostate cancer, cervical cancer, a type of brain tumor, and the risk of leukemia in the offspring of women who use it during pregnancy." http://lungcancer.about.com/od/causesoflungcance1/f/marijuana.htm

There are conflicting studies, the truth is we don't really know, it could increase the risk, have little to no effect, or even reduce the risk of lung cancer depending on which study you read. But edibles and vaping are easy ways around the inhalation of smoke to get high.
