Jon Hanna is best known as the producer of Mind States--a conference series that explores various methods for altering consciousness. He has spoken internationally on the topic of visionary art and entheogens, showcasing collections of psychedelic art and hallucinatory animation at events in Brazil, Canada, Costa Rica, Germany, Jamaica, Mexico, Portugal, and Switzerland. In the arena of harm reduction, he has volunteered as a sitter at Burning Man, the BOOM festival, and other gatherings.

Author of the Psychedelic Resource List, Hanna is considered somewhat of a "psychedelic consumer advocate", highlighting reputable vendors as well as exposing companies, events, and individuals that have less than scrupulous records. He has written articles, columns, and reviews for Entheogene Blätter, The Entheogen Review, Erowid, Heads, High Times, the MAPS Bulletin, Morbid Curiosity, The Resonance Project, and Skunk.

In 2008, Hanna began working as a Senior Editor for Erowid Center. In 2013, Hanna moved on to better pay and greener pastures, using his excellent editing skills and world-class knowledge of psychoactives to help others.
