Around the beginning of the micro-dosing trend, I went to Colorado for a String Cheese Incident concert, and met a group of people that follow the band on your and attend multiple shows. Some of these people had been frying acid for 4 days in a row, and doing nothing of consequence.

Using psychedelics to improve anything (except maybe some forms of art) seems to me like when writers would drink to help them write. There's never going to be any rigorous evidence for any benefit.
