Erowid, also called Erowid Center, is a 501(c)(3) non-profit educational organization that provides information about psychoactive plants and chemicals as well as activities that can produce altered states of consciousness such as meditation and lucid dreaming.
Erowid documents legal and illegal substances, including their intended and adverse effects. Information on Erowid.org is gathered from diverse sources including published literature, experts in related fields, and the experiences of the general public. Erowid acts as a publisher of new information as well as a library for the collection of documents and images published elsewhere.
Erowid was founded in April 1995 as a small business; their website appeared six months later. The name "Erowid" was chosen to reflect the organization's stated philosophy of education. Using Proto-Indo-European linguistic roots, "Erowid" roughly translates into "Earth Wisdom" (er meaning 'earth,' 'exist,' and 'be born' and wid meaning 'knowledge' / 'wisdom' or 'to see'). In 2005, the 501(c)(3) non-profit educational organization "Erowid Center" was formed. The organization is supported by donations, and its website is free of advertisements. Although its primary focus is on the website, Erowid Center also provides research and data for other harm reduction, health, and educational organizations. The organization is based in Northern California and the main servers are located in San Francisco.
