I didn't downvote, but I will say that what worries me far more than the effect of any drugs is your apparent desire to use the Government to impose your personal tastes and opinions on the population. Stoners will occasionally crash cars and waste their lives (at least in some peoples' opinions - is it not their life to live as they choose?) and that can be terrible for the people affected. A widespread desire to ban things that you don't like based on scant evidence and enforce those bans with increasingly military-like police forces is what leads to things like the US imprisoning a greater percentage of the population than actual police states. I ask that you reconsider your desire to impose your views of how other people should behave on them, using Government force if necessary. People who lead their societies down that path have a nasty tendency to find the things that they personally like get banned next.
