Nah. I started using the noble weed when I was 12, and I am 67 now. Never did coke, heroin, meth, prescription pills, or any other kind of drugs ....nothing other than dropped some acid once ( and that was enough for me. Never touched it again. ) and used to get hold of the occasional peyote buttons or mescaline in the early 70's. I know hundreds of people like me that were pot heads all their lives and never tried any other drug. And many a meth, coke, heroin and pain pill addict that never ever smoked a joint. Alcohol is probably the bigger gateway drug, truth be told. I always said I would 1000's times rather my kids or grandkids smoked pot that ever drink or smoke a cigarette.
