I have given out a certain of points and bubbles in my life under harm reduction programs. These efforts (which I've worked at but not been central to) have had a measurable and positive impact on syphilis rates in rural Colorado among a number of other metrics.
While I think it's not great folks use, the worst parts of many of these things are created by states sanctioning things. People mess their lives up all kinds of ways and creating a black market pretty much just changes the incentive structures. It just makes it more likely folks will do fent because that's what they can find, but if they can't find that they'll drink hand sanitizer.
Unless you think that these folks should kill themselves off using tainted drugs (which was a policy pursued by the US government during alcohol prohibition), then legalization program makes some sense.
Introducing a government monopoly on things like heroin would have a lot of up-sides with the downsides largely being slightly skewed versions what we have right now.
I don't think that marketing heroin in social media apps the way gambling does is a sane idea, but I also don't think gambling apps should be allowed to market themselves.
Like a lot of things, I believe having a government undercut the market for things would have a positive impact, but depending on your view of the relationship between the DEA and the CIA you might think that is already happening but in the worst of all possible ways,
There's already causal inference evidence out there indicating that needle exchange programs reduce rates of HIV and other bloodborne infections, but increase the risk of fatal overdose. If simply making fresh needles more accessible increases overdose rates, I suspect legalizing heroin would have a much larger effect.
But I personally am not sure what the causal relationship between access "clean needles" and "fatally overdosing" is, though I would be interesting in hearing that account.
jfc this is just terminal contrarianism. do we really need to debate whether it's harmful for extremely addictive drugs to be widely available? the Chinese literally fought wars over this
If we can create a situation where those people aren't breaking into cars, stripping the wire out of buildings, or dying in the street - that would be a net positive.
Prohibition has five decades of abject failure under its belt. Try something else.
