General Drugs question....

[lagerized]

Say this geezer swim had enjoyed and mucked around with drugs for several years yeah maybe from when he was 17-22, in that time he had plenty of speed, 25 g's of coke, 200 odd pills and a few other bits and pieces. Then one day he decided he needed to grow up a little and concentrate on his education and work. He starts to get more healthy exercise and the only stuff he does now is get drunk once or twice a week. Would his drug binges when he was younger come back to hurt him in later life? Or would him staying off the stuff apart from maybe once or twice a year mean that his head will be straight for good? Bit of an open question that swim wants to know the answer to but wandered if anyone else knew someone who was in a situation where they done loads of stuff in there younger days but not much now, is later life effected too much? Or does staying of the stuff for long periods of time really sort you out??
