Bobert, I think you must have either misremembered this, are joking, or were taken in by a scam. Pot smokers live longer than non-potheads?! Pot is *more* carsongenic than tobacco. Long term use (shorter term in some, depends on body mass etc.) also leads to associated mental health problems, such as paranoia.
