The History Of Psychedelic Drugs

Before we get into a more detailed history of psychedelic drugs, let’s clarify what we mean by psychedelic. The term is commonly used to refer to any drugs that have a hallucinogenic effect. However, strictly speaking, it refers only to drugs that contain lysergic acid diethylamide (LSD). In practice, however, both terms are often used interchangeably, and there is some overlap between them.
