As mentioned downthread, that was my experience, so YMMV, as Teh Intertubes like to say. Besides that, when you add:
I’m sorry to hear of your acquaintance’s problems, but I’ve been around a pretty solid number of people who’ve experimented regularly with such substances, and to a person they’re nominally sane. I’m too lazy to look at the moment, but I would suspect the scientific literature would back me up on the relatively low number of serious mental issues correlated with the use of psychedelics. And I’d still argue that the government has presented false or misleading advertising about the dangers of drug use.
