There is the famous quote by Steve Jobs
Taking LSD was a profound experience, one of the most important things in my life. LSD shows you that there’s another side to the coin, and you can’t remember it when it wears off, but you know it. It reinforced my sense of what was important—creating great things instead of making money, putting things back into the stream of history and of human consciousness as much as I could.
It seems to have worked out rather well for him.
Then there is Francis Crick, John C. Lilly, Kary Mullis, Ralph Abraham, Stephen Jay Gould which says,
Many famous scientists and inventors of all ages have admitted to taking psychedelic drugs. Some of them have even claimed that recreational drugs enhance creativity, inventiveness and intelligence, while others have gone one to advocate drug usage.
Obviously this is anecdotal cherry-picked evidence and full of the various biases; LSD-using underachievers are most likely go quite underreported in the media and "Hey I did it without LSD!" isn't the most popular way to start a Nobel acceptance speech.
Is there a positive correlation between trying LSD at least once and high achievement?
