I think that’s a legitimate approach. Though I personally think all substances should be decriminalized (rather than legalized) as in the case of things like heroin addiction the addicts fear of punishment and the stigma keeps people from seeking help and ultimately we should want them to seek help.
Alcoholism would exist with or without alcohol being illegal, the only difference would be that drinking alcohol would be more dangerous for those wishing to drink responsibly and those drinking irresponsibly would have less options to become well.
Regarding these other substances though I wholeheartedly agree real research is needed. It’s one of the really tragic things about the war on drugs actually, that research was completely stopped. Even if you keep a substance illegal, researchers should still be allowed to investigate these things. There’s life changing non mind altering treatment for cluster headaches for example that has been nearly impossible to research until recently and even still it’s never going to see the light of day in this political climate around drug paranoia even though it has zero mind altering impacts (it’s a chemical related to lsd where they modified to remove the altering effect).
I’m pretty ok with substances being banned (albeit not my preference) in general as long as research is allowed to continue and the ban persists based on information produced from that research. I.E. it’s not based on fear mongering but science.
Another aside, one of the main reasons I think decriminalization (for all) and legalization (for some) is pretty compelling is that it makes it a lot easier to regulate to ensure the products themselves are safe. A large number of the safety issues simply comes from people obtaining unsafe/fake products. Though regulation you have consistency. Nowadays with recreational marijuana you can see the lab report for every single product. Back in the day you just had to rely on some shady character telling you “it’s good”.
People are going to be doing these things, keeping them illegal in the way we have been (serious jail times for personal possession) only creates more harm and cost to society rather than alleviate it (the supposed goal). The war on drugs has created a quite insane cost through mandatory minimums and three strikes laws.. if the goal was to reduce cost to society we’d have saved money providing government supplied drugs to addicts. If the goal is to “save” or prevent harm to addicts, locking them up and making them felons seems to be having the opposite effect. They fear seeking help, and once caught up in our penal system it’s hard to escape.
So what part of criminalization is really benefiting us?
