The thing that bothers me is that anyone who thinks they should decide for other people what (non-poisonous) chemicals they should put in their body is obviously so crazy that their opinion should be excluded from serious consideration on the matter. (This goes double if the person hasn't ever even tried the chemical(s) in question!)

Anti-drug hysteria has caused far more human destruction than all the bad trips and psychotic episodes put together. There are thousands, perhaps millions, of people in prison right now for illegal drugs. In some cases they had their lives ruined over nothing worse than a few grams of weed.
