[Hydraulix989]

I'm a SV entrepreneur who is pretty well-connected with the community here (only mentioning this for the sake of credibility).

Maybe it's because I missed Burning Man this year, but I haven't heard of anybody doing this outside of articles on Tech Crunch that say people are (let alone normal hallucinogens).

Marijuana or Adderall, sure (Meadow and Eaze are doing well here); maybe even the /r/nootropics stack, but not hallucinogenic substances.

I know people who have experimented with shrooms, but they don't consider them a "drug of choice," let alone a productivity enhancer by any means. In fact, one of my acquaintances ended up going off the deep end when he started taking LSD. It was a really sad story.
