Many of us would never have tried psychedelics if it weren't for Leary's popularizing them.

Being raised a Jew in southern California in the 1950s and 1960s, my religious training emphasized learning the Hebrew language and Jewish festivals, history, and culture. We also remembered the Holocaust and supported the newly formed Jewish state of Israel.

The resemblance of ... the alien abduction of 'experiencers' to the contracts described by our own volunteers is undeniable. How can anyone doubt, after reading our accounts... that DMT elicits 'typical' alien encounters?

Aaron was one of the few Jewish volunteers in our study, and I felt a certain kinship with him at that level.

The discovery of DMT in the human body stimulated much less fanfare than did that of endorphins. Anti-psychedelic-drug sentiment sweeping the USA at the time actually turned researchers against studying endogenous DMT. The discoverers of endorphins, in contrast, won Nobel Prizes.

The history of human use of plants, mushrooms, and animals for their psychedelic effects is far older than written history, and probably predates the appearance of the modern human species.
