The ibogaine medical subculture

Introduction

Ibogaine is a naturally occurring indole alkaloid that has been used outside formal medicine in a growing global ‘‘medical subculture’’ to treat substance-related disorders, most notably opioid withdrawal. Historically, iboga has a long ritual use in the Bwiti religion of West Central Africa, but its contemporary use for addiction treatment originates in lay experimenters in the 1960s and subsequent informal clinical and research uses. Preclinical studies, a small body of open‑label human case series, and pharmacological investigations have suggested that ibogaine and related alkaloids can attenuate opioid withdrawal signs and reduce drug self‑administration in animal models; proposed mechanisms include effects on nicotinic receptors, modulation of intracellular signalling linked to opioid receptors, and influences on dopaminergic pathways. The subjective state produced by ibogaine has been described as a ‘‘waking dream’’ and its pattern of use — especially for opioid withdrawal — distinguishes it from classical serotonergic hallucinogens. Alper and colleagues set out to characterise that ibogaine medical subculture outside Africa and to collect systematic quantitative data about who takes ibogaine and for what purposes. Specifically, the study aimed to (1) produce a qualitative typology of the different ‘‘scenes’’ in which ibogaine is provided, and (2) obtain provider‑reported cumulative counts and indications (substance-related disorders in general and acute opioid withdrawal in particular). The paper therefore combines participant‑observer ethnographic methods with systematic searches of publicly available ‘‘grey’’ and academic literature to update the authors' earlier work and to quantify the scale and focus of contemporary ibogaine use.
