In general though, anecdotes of psychedelics curing a number of mental illnesses are starting to become well supported by the scientific literature. The wide variety of benefits from psychedelics - particularly psilocybin - are being actively investigated in quite a few clinical trials. We're talking about safe and long-term cures for depression, anxiety, addiction - while also promoting neurogenesis and neuroplasticity [1][2][3].
I believe we're on the brink of a modern psychedelic revolution in medicine, one that has been long overdue since these effects were documented and investigated over 70 years ago - and known to ancient indigenous cultures for thousands of years.

but earlier in the article:

Sounds like it was pretty touch and go there for at least those three people.
I don't really have a notion of how widespread LSD usage has been throughout history (thousand of users? millions of users? ) so the toxicity anecdote is interesting, especially since acid has a reputation for being such a heavy drug.
