Stanley was one of the first people to manufacture mass quantities of LSD. His LSD is still known for its quality and purity. Between 1965 and 1967, Stanley produced more than 1.25 million doses of LSD. This amount of quality LSD was responsible for the wide popularity of the drug, and the development of an anti-authoritarian, anti-war counter-culture. From the 'Sunset Strip Riots' in Los Angeles, to the Summer of Love in San Francisco's Haight-Ashbury was described as "the biggest LSD party in history.". The name "Owsley" was linked to cheap LSD of good quality.
