But removing prohibition is a far cry from providing free heroin to addicts... I understand the argument about removing the black market, but after seeing San Francisco in person it's hard to agree that free drugs and paraphernalia makes things better overall.
If my friend became a heroin addict, out of care for him or her I would not provide them with heroin even if I could afford it. Why should I treat other fellow humans worse?
Why is it different when we're speaking at a societal level? Love for neighbors should increase, not invert, when the number of individuals concerned increases.
Giving meth addicts forms of meth that are produced more cleanly would reduce the level of psychosis and would further reduce the price of meth to a point where it may not be profitable to produce (it's already cheap to the point where it's nearly unprofitable - it requires massive volume).
Giving addicts access to clean drugs provides you an opportunity to help them, a place to keep them away from others while they're using, a way to ensure they don't die while using, reduces funding to organized crime, and removes their need to commit crimes to fund their habits.
You may see it as treating them poorly, but ultimately, you're doing them and the rest of society a benefit.
Learn some history. We tried this. It failed spectacularly, as if in slow motion, for decade after decade.
Which is not to say there aren't humane reasons to fix these problems, especially if they aren't effective at reducing drug use anyway. But yeah, drugs actually are a huge problem and would be even if they were legal and free for all.
I'm pointing out that alcohol causes immense harms despite being legal, so likely other drugs too would still cause considerable harms when legal (even though yes, it's likely some, like cannabis, would be less harmful than alcohol almost no matter what total consumption settles on under legalization).
I was not arguing about why things are legal or not, only challenging the assertion that drugs aren't very harmful when legal.
