As this area was gaining legitimacy in the late 70s, Reagan and the War on Drugs happened, which made legally obtaining the substances difficult, and research funding dried out.
A great shame, because psychedelic therapy has so much potential. Just a single data point, but my life was turned around by some formational experiences on LSD and Psilocybin. Glad to see research heating up in this area again.
Except for only one friend, who ended up suicidal and delusional beyond repair, frequent mental hospital dweller (although all doctors said drugs could only exacerbate a pre-existing condition, but not create it from scratch).
I wonder why so big discrepancy between internet and real life here.
