Earth Erowid
Earth is the Technical Director of the non-profit educational organization Erowid Center and Executive Editor of Erowid Extracts. In 1995, along with his partner Fire, he co-founded, an independent, public, web-based library that collects, reviews, and publishes data about psychoactive plants, drugs, technologies, and practices. He is Chief Software Engineer of the site, which hosts more than 58,000 documents and images and receives over 90,000 unique visitors each day. Earth designs and implements the custom software systems necessary for managing the large flow of information through the site and is the lead editor responsible for scientific information published by Erowid.

Earth has worked in the field of psychoactive information distribution since the early 1990s and has written extensively on the topic. He has co-authored academic posters, his writing has appeared in numerous print publications, and he has been interviewed by major news organizations about his work. In 2011, along with Fire, Earth received the Drug Policy Alliance's Dr. Andrew Weil Award for Achievement in the Field of Drug Education. Earth and Fire have spoken internationally at academic and professional conferences sponsored by groups as diverse as the National Institute on Drug Abuse, the North American Association of Clinical Toxicologists, Mind States, Entheogenesis Australis, the Mycological Society of San Francisco, the Multidisciplinary Association for Psychedelic Studies, and the American College of Medical Toxicology to name a few. In 2012, they became members of the Advisory Council of Students for Sensible Drug Policy.
