Snu is an amateur ethnobotanist specialising in the study of psychoactive plants, fungi and animals. He is particularly interested in their use in shamanism and other spiritual practices, and is passionate about their conservation and responsible use. His book Garden of Eden, an encyclopedia devoted to this topic, was published in 2009 ( https://troutsnotes.com/garden-eden/ ), and a revised and expanded edition is being worked on. Snu's writing has also appeared in the journal Eleusis, and he was one of many contributors to the Manual Of Psychedelic Support, and ESPD50 (Ethnopharmacologic Search For Psychoactive Drugs 50th anniversary 2017).
