Thirty years after its founding, Erowid — a once-obscure website for sharing drug experiences — has evolved into one of the world’s most significant repositories of information on psychoactive substances. What began in 1995 as a small, independent project has become a valuable reference for researchers, doctors, and policymakers studying the use and effects of both legal and illegal drugs.
Founded by two graduates known by their pseudonyms Earth and Fire, Erowid started as a grassroots attempt to fill a gap in reliable drug information at a time when psychedelics and other controlled substances were highly restricted. The website allows users to submit first-hand accounts of their experiences — known as “trip reports” — with substances ranging from caffeine and cannabis to LSD and heroin. Today, its “Experience Vault” contains over 45,000 such reports.
The site’s growth coincided with an era when online forums were emerging as communities for niche interests. For many, Erowid became the first safe space to share and access knowledge about drugs outside of government or academic settings. “It created an environment for people to connect and share information, but also one for younger people experimenting for the first time,” said author and cultural commentator Erik Davis.
By the early 2000s, Erowid had grown from a subcultural hub into a mainstream data source. It was cited in peer-reviewed journals, government reports, and even by global health agencies. Today, it boasts over 5,000 citations on Google Scholar, and millions of visitors each year. Researchers use it to study new synthetic “research chemicals,” the psychological effects of psychedelics, and even sensory phenomena like synaesthesia.
“Erowid was invaluable when there was so little published academic research on psychoactive drugs,” said David Luke, associate professor of psychology at the University of Greenwich. “It has enabled a lot of science that would otherwise not have been possible.”
The platform’s influence extends beyond academia. Emergency doctors, policy-makers, and law enforcement agencies rely on Erowid to identify emerging substances and understand their effects. Institutions such as the US National Institute on Drug Abuse, the World Health Organization, and the UK government have all referenced Erowid’s data.
Despite its usefulness, Erowid has faced criticism for hosting information that could potentially be misused. However, supporters argue that its focus on harm reduction and education has saved lives by filling a gap left by official channels.
Today, as psychedelics gain renewed scientific and medical legitimacy, Erowid’s founders’ original vision — to create a trusted, open-source archive of drug knowledge — seems more relevant than ever. What began as a digital experiment by two idealists has grown into an indispensable part of the global conversation on drugs, safety, and human experience.
