A historical timeline of the relationship between psychedelics and humans
22nd June 2016

This was an attempt to make a really comprehensive timeline of psychedelic/"hallucinogenic" drugs.

It's most certainly not exhaustive.

It is supposed to focus more on the most ancient known events. In regards to more recent events, it only includes the more important stuff.

In order to give a view of the context of the times, we also added events seemingly not directly related to psychedelic drugs. These are highlighted in gray.

Note: Because this file is large, it sometimes won't completely load the first time. To check if it has completely loaded, it must end with a list of references at the bottom of the page.

They call this drug Soma and write about it in the Vedas.

1992 On a tour in UK (that would be recorded in Revelations) Bill Hicks states his belief that certain drugs were meant to grow naturally upon our planet to help speed up and facilitate our evolution. Talking about magic mushrooms he says: “Do you think magic mushrooms growing on the top of cows' shit was an accident? Where do you think the phrase 'that's good shit' came from? Why do you think Hindus think cows are holy? 'Holy shit...' Why do I think McDonald's is the Antichrist? That[the mushroom]'s God's little accelerator pad for our evolution.” He then does a representation of how he believes humans evolved from apes: being "probably too stupid to catch a cow", our ancestor apes ate a mushroom that was growing in cow's dung, then started laughing and (implying they were enlightened) said "I think we can go to the moon..."
