Dimitri had been addicted to heroin for 20 years when a single dose of ibogaine, a powerful hallucinogen derived from the root of a West African plant, stopped his addiction cold. Dimitri has since devoted his life to helping other addicts as an ibogaine provider, despite the fact ibogaine is considered contraband in the United States. The known side effects from ibogaine include violent purging, psychedelic visions, and temporary paralysis. While trying to treat a client, things go poorly and Dimitri finds himself seeking personal guidance.
