reminds me of those teenage girls sentto a teen bootcamp in the US - one was a heavy weed smoker.
before she went, her mother blamed the drugs - for her daughters lifeless, useless behaviour.
after the camp, the girl stopped smoking . but her behaviour remaind the same. the durgs were just a symptom of her unhappiness.
the research done by the government found that weed use in people (classically university stiudents) who were well off had virtualy no negative effect. they stop smoking, get jobs, get married...some of them even become cabinet ministers.
and anecdotaly, that's how things have gone for even the heaviest weed smokers i knew at university. (maybe not the cabinet minister thing)
on a slightly different point, i always wonder why parents of heavy smokers want it to be made more illegal - whatever harm the drug does, a prison sentence is most grievously harmful.
i thought one of the reasons for the original down grading as Jack Straws son sold a newsreporter some weed.
i really don't believe sending someone to jail is an effective form of therapy. Having a criminal record definitely does make life mmuch harder.
