Netflix recently made "The Sunshine Makers" available for streaming.

This 2015 documentary chronicles the life and times of two men, Nicholas Sand and Tim Scully, who together set in motion the psychedelic revolution of the late 1960's. Both men were idealists who thought that if everyone would just drop a little acid, the world would be a better place. People would be kinder to each other and the planet, have a larger awareness outside of one's own selfish desires, etc, etc.

Scully was a sharp scientist who knew the formula to make lysergic acid diethylamide (LSD) and had a method to produce and tablet it for distribution. Sand was driven by idealism and spiritualism and bent on bringing the psychedelic experience to the masses. The two became underground chemists who made the drug and did indeed change the world...for a little while anyway. They made massive amounts of LSD and got it in the hands of an entire generation, globally.
