i was a coke/ heroin addict for many yrs before i got help and there is no comparision as a matter of fact the weed was what helped me to get off that shit that and several yrs of attending a methadone clinic.. as long as i dont run out of weed i dont really think about using hard drugs that much any more but im sure your doc was just telling you what he had been trained to tell you.. its a shame that more docs wont take the time to learn the truth about cannibis and its many medical uses
