I did all my "experiments" in my later 20's. Many good experiences and I stopped when, honestly, they started be bad for for me. It also coincided a time when psilocybin was banned in London, UK (it was legal during the years I experimented). I did all my "investigations" during the legal times. When the trips started to be increasingly disturbing, I stopped.
