I've smoked it pretty much every day for the last 10 years, I have a successful job, good kids, a home etc etc. Not a hint of mental illness of any degree and I'm still motivated to get up and do things everyday.

I smoke it because it helps me sleep and stops my insomnia. I smoke it in private, when kids are in bed of an evening. I don't see what harm that does to anyone.

People who are already a bit crazy might go crazier, but they are already doomed, regardless of whatever drug they choose, I think its the people, not the drug that is the problem.

At least the US is starting to wake up to the benefits, if only the UK would be the same. We have a terrible drinking culture, such a drain on so many state resources. Have you ever seen two pot heads fight or do stuff they really regret, or smash things up? Hardly ever. On drink, its almost guaranteed.
