There was a lot of scientific information about psychedelics from the 50s and 60s. Illegalization and stigmatization of psychedelics was largely political and antagonistic towards the scientific community that was doing actual research. Also anyone curious enough to try out psychedelics will realize they're very different from narcotics. In the US there was always a subculture that accepted use of psychedelics, information passing through books, writings, unofficial journals etc. So to say the information wasn't accessible just isn't true. It may have been hidden, but if it was it was in plain sight and to anyone curious this world was easily accessible and accepting.
