greatnan you don't, but many people do now stigmatise smoking (if not smokers). So, to me, that is a good example of a legal drug (nicotine) which is clearly harmful, and which now has had controls put in place around its use and therefore smoking is down and the current drop in numbers of young people presenting for help with problem drug use is thought (by some) to perhaps have something to do with the decrease in smoking, the first 'gateway drug' for many young people. Heroin and crack use is 'going out of fashion' it is thought from people having seen and experienced at first hand the devastation it has wrought on generations that went before them. So that's a good deterrent too then, and fits in with the comment pogs made. Each drug user of course is unique, so not all are young, not all become addicted etc. Another point to consider - many drug users stop using in prison - it provides them with the respite/change of scene/drug treatment comes to them instead of them having to go and find it etc. As an aside, I found it really interesting to hear the other day that many prisoners, especially drug users, benefit immensely from the routine and the three square meals a day - they put on weight, their health and wellbeing improve etc. I think it was on Sunday Morning Live. The biggest rising problem in addiction as was said on another thread is addiction to prescribed medication and over the counter stuff, and 'legal highs' which are proliferating and mutating at a rate that no one will ever be able to stop.
