 The story of Gordon Wasson's visit to Maria Sabina is even more tangled and ethically problematic. For one thing, he wasn't alone. Apparently, the CIA knew about the trip and followed the Wassons down to Sabina's village, hoping to discover drugs that could be used as weapons for mind control. And the Wassons themselves lied to Sabina, who had said from the beginning that she did not want any publicity, let alone fame.
