Again avoiding the point that decriminalisation is actually more likely to reduce the number of users rather than increase it. And avoiding the point that if cannabis use would be a burden on the NHS if it was legal then it already would be a burden now. But it's not. Fat people are the big problem.I didn't ignore it, I missed it, or skimmed over it, as I was mostly responding to dave's posts.
If more people take it throughout their lives, I think that will have a negative effect on their long term health, and therefore have an effect on the NHS.
