ELI5: how do illegal drug prices remain more or less constant while everything else increases in price?
gpt
They don't.  Cocaine was 3 times more expensive, when everything is adjusted for, in the 80s than now.  Tells you something about the economy in the 80s.  The price of an ounce of high grade marijuana has also dropped significantly in the past ten years.  Used to be an ounce of the best stuff would be between 350-400, now it can be had for 250-300.  Acid was 2 bucks a hit when that dude was making it in the abandoned missile silo in the 90s, now the going rate is 10.  Heroin has dropped significantly in price and increased in purity since the invasion of Afghanistan.  You probably just haven't been using illegal drugs long enough to notice the price fluctuations.  Give it time, you will.
