"I don't care if people use cannabis (and I am strongly in favour of legalisation) but I fucking hate the refusal of many cannabis users to even contemplate any negative effects of cannabis." Don't get me wrong; I don't refuse to contemplate the negative effects of cannabis, of which quite a few have been hypothesized, some observed. When I said "alcohol is probably much worse than weed," I didn't say "weed is a free lunch." Just want to make sure I'm clear on that. There are cannabinoid receptors in the brain (and other organs). Our current understanding of them is far from complete, and we know that smoking weed habitually will reregulate them, and not necessarily for the better. I'm not one of those hippy-dippy types who thinks there are no ramifications involved in smoking weed.
