Ceremonial Chemicals
Most hackers don't smoke tobacco, and use alcohol in moderation if at all
(though there is a visible contingent of exotic-beer fanciers, and a few
hackers are serious oenophiles). Limited use of non-addictive psychedelic
drugs, such as cannabis, LSD, psilocybin, and 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.
