I totally agree about the reality of mental health issues in the US. And I definitely agree we need more studies on LSD and its effects. It's very unfortunate that LSD is schedule 1, meaning that research is exceedingly difficult to do on large scales, which essentially means that debates like this are only really supported by anecdotes and fear on both sides.
I'd like to say I'm not pro-drugs. I'm just pro-science and anti-war on drugs, which I'll assume you are too. If there was a scientific consensus on how often normal doses of LSD caused things like visual snow or, more severely, the onset of schizophrenia or similar disorders I think the world would be a better place. If LSD indeed caused more harm to the world than existing popular drugs like alcohol, then I think anyone who trusts science including myself would say "Okay, let's stop doing them". But until then, it's just hearsay anecdotal evidence that gets us nowhere. If it does get us somewhere, it's been historically in the direction of demonizing those who do drugs which I think has had a negative effect on society as a whole.
In a vacuum your experiment just might work, but probably not in 2023 American society. There is a lot more non-biased scientific study that needs done before unleashing these powerful substances on the population. I would suggest removing bias and looking at it in a neutral way, as I'm sure a happy medium can be established here.
