A Brief History of Psychedelics
Historical Overview
Ancient and Indigenous Contexts
Many psychedelic plants and fungi have been used for centuries in Indigenous and ceremonial settings. These traditions often emphasize ritual, community, healing, and spiritual meaning rather than individual intoxication.
Modern Scientific Era
In the mid-20th century, scientists began studying substances such as LSD and psilocybin for psychiatry and psychotherapy. This period produced early enthusiasm, followed by legal restrictions and a long decline in research.
Context Matters
Modern research often draws on older cultural practices, but scientific trials use different standards, goals, and safeguards.
