Two things wrong with your reply.  Dope is illegal here.  Legalizing the medical and recreational sale of cannabis hasn't resulted in a halt of all illegal sale of the plant within the borders of our State, not to mention the weed grown here and exported in violation of both State and federal law.  And yes, it is habit forming. Perhaps not physically as an opiate would be, but it has been shown to be psychologically addictive and therefore habit forming.
