Are you sure drugs can be regulated the way alcohol can? They are both more addictive and behavior changing than alcohol. I don't have a solution as I also dislike the current "war" on drugs. But I suspect regulating safe fentanyl use will be way, way harder than regulating safe scotch use.
it doesn't have to be safe, just legal. If people choose it, and fuck themselves up, they're free to do so. They're doing it today already, but with the added benefit of being illegal and force resources into a drug war against the cartels.
When I was living in the USA I felt this way, but after moving to Japan, a country that is very strict on drugs and has eliminated it from the public consciousness, I feel my opinions changing. I trust myself to be able to use/not use drugs responsibly but given how irresponsible most people are, it’s undeniable the positive effects on society of NOT letting people totally destroy their brains and lives, and it is utterly daunting to think of what it would take to get the USA back on its feet re drugs.
