With the proper approach and care, these substances can be incredibly powerful and beneficial. I can't wait until the research eventually forces the hand of those who mistakenly believe otherwise. Psylocybin and perhaps LSD should be legal on some level in our lifetime hopefully.
"I can't wait until the research eventually forces the hand of those who mistakenly believe otherwise."
I wouldn't be so optimistic, we still can't even "prove" to some that vaccination is beneficial. Even if research found a valid application for hallucinogens, I doubt they will be legal or widely available in anytime soon except, maybe, as carefully dosed therapy drug in extreme cases (pretty much like opiates).
The vaccination situation proves that there are idiots in the world, if you take those people as example of "can't prove X" then we might as well stop all scientific research right now. There's also people who believe the world is only a few thousand years old.
To get societal (and legal) change, you don't need to convince 100% of the crazies. Convincing most of the sane people is enough.
(I'm not saying only crazies are against psychedelics, just that the vaccination comparison isn't useful.)
