Great, now do psilocybin, LSD and MDMA.
Do all of them. To me, government exists to mediate interactions between parties. Not to get involved in personal choices. If someone wants to rip fat lines of coke, good for them. Not my business.
We don't live in libertarian utopia, let's first focus on substances that are *obviously* misclassified, the ones cited before have actual benefits, the most obvious one being psilocybin.
Do they need to have benefits? Whether they are beneficial or not people are using drugs like MDMA. Making them illegal has only caused harm.
