The movie Fear and Loathing in Las Vegas brought the word Adrenochrome to light in the 90’s but Terrance McKenna wrote about it 50+ years earlier. I have read theories of people like Aleister Crowley and many others from the turn of the century and possibly for thousands of years ago as well.

All the historical writings of the Inca or Aztecs doing ritualist killings that just may have been practices of adrenochrome extraction for the elite or maybe aliens from a hidden land. There are maps from the 1600 showing many more continents beyond the Antarctica continent.
