I personally know of two people in my social circles who committed suicides on psychedelics. You can definitely argue that such a thing might have happened even without the psychedelics but I'm convinced that being in that altered state of mind pushed these people over the edge (literally in one case).
I'm personally pro-legalization of a lot of drugs. I do not want to close myself off to the clear negative effects of said drugs though. I think we should all remain honest and proportionate about them.
I did a quick search on google scholar. Don't see any articles linking psychedelic use to suicide and there is a study of 130,000 people failing to find a link:
A study failing to find a link between psychedelic use and suicide doesn't mean that psychedelics never cause suicide, it means that on average they don't seem to.
Banning psychedelics will lead to at least some deaths. Not banning psychedelics will lead to at least some deaths. This is true of many many policies.
Ultimately the question is a cost-benefit analysis.
