I didn't say it doesn't affect your health--I said the effect was statistically insignificant, for the reason, obvious to anyone whose brain hasn't been fried by uxorious anti-drug propaganda, that marijuana doesn't addict you to the extreme degree that tobacco does. But I'm game, show me the stats and I'll retract. Show me the massive clinics where they treat marijuana-induced lung cancer victims. Maybe you can find them if you look next door to the clinics where they treat the 100,000 or so mortal victims of tobacco, a legal recreational drug, each year.
