Legalize everything!= Everyone should be using drugs. This is just one step in what should be a public health approach to drug use/abuse. Take away the lock them up because they are weak minded degenerates approach to drug use. I don’t see any dissonance in saying that drugs should be decriminalized and or legal in some cases but I also don’t think most people should use drugs regularly. If someone is abusing drugs it should certainly be cheaper to provide them with mental health care than locking them up in jail. Hard drugs like heroin and cocaine would be safer if they were not sold on the black market. I think that is a net positive vs the status quo- which is a game of “Is It Fentanyl?!?”™ currently. Should people be using those drugs? I don’t know. I personally wouldn’t want to even if I could buy them from a store.
As for cannabis, I’m convinced that for 90+% of the populous* it’s safer than alcohol.
*I think anyone with family history of schizophrenia should avoid weed and probably all intoxicants.
