This book is dedicated to Sasha Shulgin (1925–2014), whose rediscovery of MDMA brought it into modern consciousness. His commitment to the liberation of the human spirit made him a quintessentially American pioneer and hero. Every time you drink the water, remember the one who dug the well.

And to my wife Shelley, who with her unfailing love, support, and buoyant spirit is the light of my life.
