There's also the opioid epidemic and amphetamine epidemic. They're pretty hard to justify in my opinion. Not that other countries don't have issues, but it's less common in democracies that that these things are pushed onto people by the govt through lobbying.
I live in a city with defacto legal drugs (including up to cocaine, crack and meth, but admittedly no opoids except hydrocodone) and there's no societal collapse nor any epidemic to be seen.
The opioid and amphetamine problems are due to drug relations in the US. It would have been better to not prohibit drugs. We are finally starting to see the rollback for marijuana. The amount of damage to civil liberties and lives lost to the drug war should be exhibit A in any argument about regulation.
