We don’t often think about it in this way, but caffeine is a psychoactive substance that changes our consciousness. It’s just that we’ve accepted it, and many don’t mind being dependent on it. The reason for that is simple: caffeine aligns with society’s goals.

We’ll explore that question and consider how opium, caffeine, and mescaline impact consciousness, culture, and society.
A quick note before we begin: This book contains discussions of drug use and is not intended to encourage the consumption of illicit substances.
