Persinger’s summary from the end of the lecture:

  • Psychedelic drugs are effective because they imitate the chemicals the brain produces itself.
  • All of us have the ability to make these compounds or they wouldn’t be effective.
  • Some people produce more of these substances than others.
  • Anyone who can control consciousness using drugs can control the population because they can control the sense of self.
