Are there known philosophers that did drugs?

Don't get me wrong, I'm a history and philosophy student but sometimes I can't keep myself from thinking 'was this dude high or...' because sometimes the things they wrote or said are so meta and so far fetched i can't even get my head around the train of thoughts they have written down. So I thought there maybe were philosophers that actually philosophised on drugs?

Sartre's use of mescaline is well-documented (by himself). He reports that he saw crabs following him around, and they became his constant companions.

Williams James did some nitrous oxide and said it helped him understand Hegel.

Freud was known to do some cocaine.
