In this TADS game, you spend much of the time smoking marijuana and passing it around, before later taking peyote.
The author's note claims the game isn't about getting enlightened for drugs, but it's hard to know what it is about if not that. It definitely seems like a good anti-drug advertisement, given that following the drugs leads you to being a dirty, unwashed bum that children run away from.
Scattered strong profanity, extensive drug use.
