Agree with Greg Stephens here... I think the 'cannabis turns you into a loser' argument is totally wrong. The sort of people who become apathetic after smoking lots of dope would probably have done so anyway. I smoked my wee head off all through university and held down a part-time job and still managed to get a First. Likewise the 'gateway to harder drugs' theory. I've never been in the least tempted to try anything harder though I know several people who do. I just don't see the attraction. I have to say though that the gateway thing is really an argument FOR legalisation because if you have to go to a dealer to get dope, then it's putting you right in front of all those harder drugs.
