It's truly amazing that a Nobel Prize winning genius had taken Lysergic acid diethylamide, better known to most of you as LSD, when he discovered the double-helix structure of DNA almost a half-century ago, but it's true.

In fact, Dr. Francis Crick admitted he'd taken tiny amounts of LSD -- once considered an experimental drug to aid in psychotherapy -- to a fellow scientist to boost his brain power. Ever protective of his legacy, however, Crick kept his involvement with LSD under wraps and later cannabis, until this interesting report put all the pieces together.

Makes you wonder what other wonderful discoveries Crick might've made had he stayed away from LSD, one of a number of substances tested as a military weapon by Pfizer in the 1960s, and set his sights on safer, non-drug solutions to boost his brain health.
