shrooms and acid can severely affect your sense of being. would you trust an airline pilot to fly your plane while under the influence of shrooms thinking that the plane ate him or some shit like that? Of course it's easy to say that they could just ban pilots from doing that but the effects of those psychoactives take hours even days to wear off. Consistent use of any of those products WILL result in serious mental deterioration and that's the truth.

As for alcohol and cigarettes killing alot of people that's also true and you have a point because of the double standard.
