Erowid

The archive this whole field grew up reading: experience reports, dose tables, chemistry and law, kept since 1995 by a non-profit that sells nothing.

Erowid is a non-profit educational & harm-reduction resource with 60 thousand pages of online information about psychoactive drugs, plants, chemicals, and technologies including entheogens, psychedelics, new psychoactive substances, research chemicals, stimulants, depressants and pharmaceuticals. This includes traditional, spiritual, and responsible use, info on health, effects, experiences, images, research, chemistry, law, media coverage, bibliographies and a whole lot more.
