I'm sorry WHAT? I've been to many open airs and other events where MOST of the people around have been under the effect of psychedelic and in other drug-friendly places, and I have never hear manipulative shit like that ever. On the contrary, if I heard people talk about this drugs it was always "it worked for me but might be a bad experience for you", "be safe, don't take it if you're not sure" and "you can always have a great time here completely sober".
