John Higgs on the best nonfiction books about psychedelics

John Higgs 

While searching for something completely different, I stumbled upon a John Higgs article I had never seen before, from back in 2006, a piece for the Guardian on his "top ten" (actually 11) nonfiction books about psychedelics. 

Cosmic Trigger Vol. 1 by Robert Anton Wilson comes in at No. 8, and Higgs includes this sentence: "Anti-drug campaigners should distribute this book in schools, and ask children if they could handle that much madness."
