An alkaloid found in many African plants most famously Iboga, with psychedelic and hallucinogenic properties. May be unpleasant. Traditionally used in tribal environments for coming-of-age rituals, it has recently been used as an alternative treatment for drug addiction although this usage has not been backed by conclusive data in humans. Has killed in overdose.


Ibogaine is an indole alkaloid found in some plants of the Apocynaceae family such as Tabernanthe iboga, Voacanga africana and Tabernaemontana undulata. In West Central Africa, low dosages of Tabernanthe iboga extracts have been used by indigenous people against fatigue, hunger and thirst. Higher dosages capable of inducing visionary states are used for initiation rituals during religious ceremonies.

Ibogaine’s medical history in the West began in the early 1900s when it was indicated for use as a neuromuscular stimulant. In the 1940s and 1950s, its suitability as potential cardiovascular drug was studied. Later in the 1960s, the substance received much attention because of its potential applicability as an anti-addiction medication.

The pharmacology of ibogaine is complex and poorly understood. While largely behaving as a serotonergic psychedelic, ibogaine interacts with numerous brain systems including transporters, opioid receptors, sigma receptors, glutamate receptors, and nicotinic receptors. Ibogaine’s complex pharmacology entails a significant potential to generate adverse effects, particularly on the cardiovascular system.

Its use has been associated with at least 12 deaths since 1990. Ibogaine is not currently approved for any medical uses in the United States. Preliminary research in animals indicates that it could potentially be used for treatment of addiction; however, there is a lack of non-anecdotal data in humans.

Although not licensed as therapeutic drug and despite safety concerns, ibogaine is currently used as an anti-addiction medication in dozens of clinics worldwide.


The Iboga tree is the central pillar of the Bwiti religion practiced in West-Central Africa, mainly Gabon, Cameroon, and the Republic of the Congo, which uses the alkaloid-containing roots of the plant for its psychoactive properties in a number of ceremonies. Ibogaine is also used by indigenous peoples in low doses to combat fatigue, hunger, and thirst. Research of ibogaine started in late 19th century. A published description of the ceremonial use of T.

iboga in Gabon appears in 1885. Ibogaine was first extracted and crystallized from the T. iboga root in 1901.

The total synthesis of ibogaine was described in 1956 and structural elucidation by X-ray crystallography was completed in 1960.


Tryptamines share a core structure composed of a bicyclic indole heterocycle attached at R3 to an amino group via an ethyl side chain.

While ibogaine contains a tryptamine backbone, the structure features substitutions distinct from other hallucinogenic tryptamines. Ibogaine is substituted at R10 of its structure with a methoxy group.

The location of this substitution is identical to other R5 substituted tryptamines, notably 5-MeO-DMT.

The traditional amino attached ethyl chain of tryptamine is incorporated into a seven member nitrogenous azepine ring.

The azepine ring is fused to three interlocked cyclohexane rings, attached at the integrated tryptamine nitrogen of azepine and two carbons over.

Attached to the fusion of cyclohexane rings is an ethyl chain at R7. Ibogaine is obtained either by extraction from the iboga plant or by semi-synthesis from the precursor compound voacangine, another plant alkaloid.

  1. PCP
    • PCP can reduce opioid tolerance, increasing the risk of overdose
  2. N2O
    • Both substances potentiate the ataxia and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. While unconscious, vomit aspiration is a risk if not placed in the recovery position. Memory blackouts are likely.
  3. Amphetamines
    • Stimulants increase respiration rate allowing a higher dose of opiates. If the stimulant wears off first then the opiate may overcome the patient and cause respiratory arrest.
  4. MAOIs
    • Coadministration of monoamine oxidase inhibitors (MAOIs) with certain opioids has been associated with rare reports of severe and fatal adverse reactions. There appear to be two types of interaction, an excitatory and a depressive one. Symptoms of the excitatory reaction may include agitation, headache, diaphoresis, hyperpyrexia, flushing, shivering, myoclonus, rigidity, tremor, diarrhea, hypertension, tachycardia, seizures, and coma. Death has occurred in some cases.
