“AL HUBBARD IS SURELY the most improbable, intriguing, and elusive figure to grace the history of psychedelics, and that’s saying a lot. There is much we don’t know about him, and many key facts about his life are impossible to confirm, contradictory, or just plain fishy. To cite one small example, his FBI file puts his height at five feet eleven, but in photographs and videos Hubbard appears short and stocky, with a big round head topped with a crew cut; for reasons known only to himself, he often wore a paramilitary uniform and carried a Colt .45 revolver, giving the impression of a small-town sheriff.”
