Ozbabe,
of course I did not understand the risks I was taking at 15, but everyone in my family smokes a joint every now and then. They have kids, they have a job, a nice house, cars, they functionate perfectally in society.
I'm just saying that it doesn't have the same effect on anyone.
As for your question: My best friend got hooked on heroin, got into prostitution and killed herself and there was nothing I could do about it, so I do understand the risks of drug ABUSE.
There are more people who don't have a problem with it then there are who do, at least that's what it's like in my 'scene'.
Maybe legalising it could get drug addiction out of marginality, and that, is in my view, the only way to start solving the problem (because I am certainly not denying there IS one).
