Apocalypse isn’t exactly the best time to do drugs.
The biggest drop in price would be due to the fact that those who were junkies, hobos and fiends are now most likely spitters, smokers and hunters.
In the few first game years (or just seasons?), the supply of drugs will greatly exceed the demand.
And now drugs have to compete with essential goods that were dirt-cheap before the cataclysm (nutritionally dense food). Those junkies which chose to buy drugs over food are now dead.
Junkie NPCs do exist, but the effects of their “junkiness” are quite subtle - just a modifier on price of addicting stuff.
That said, the price and barter system isn’t exactly the most finished part of the game.
If someone could create a good list of proposed prices of drugs, we could update the prices.
Of course post-cataclysm drug prices will have to change to be more practical:
[ul][li]Tripping on hallucinogenic drugs can kill you far easier than it could before zeds, so big price drops here[/li]
[li]Anything that could cause severe problems in short term also gets a price drop, because no medical help means much higher risk of death[/li]
[li]Painkillers could get a price increase, even though they aren’t hard or expensive to produce, because they are now useful and not just convenient or fun[/li]
[li]Stimulants aren’t combat drugs, but they would probably get a less severe price drop than most drugs. Unless we want to reflect the “potion of speed” effects of meth and the like in the price, in which case they should be treated as combat drugs.[/li]
[li]Drugs used mostly in treatment of illnesses would get a big price drop, because natural selection would eliminate most of the people who need hard to acquire substances[/li][/ul]
