I think there's a small amount of overlap between hacker culture and drug culture. From the Jargon File: Limited use of non-addictive psychedelic drugs, such as cannabis, LSD, psilocybin, nitrous oxide, etc., used to be relatively common and is still regarded with more tolerance than in the mainstream culture. Use of `downers' and opiates, on the other hand, appears to be particularly rare; hackers seem in general to dislike drugs that make them stupid. On the third hand, many hackers regularly wire up on caffeine and/or sugar for all-night hacking runs. http://plumeria.vmth.ucdavis.edu/~saintly/bio/portrait.html#Ceremonial%20Chemicals http://plumeria.vmth.ucdavis.edu/~saintly/bio/portrait.html#...
