Abstract
Abstract Background Therapeutic properties of ibogaine in the treatment of addiction are attracting both clinicians and patients to its use. Since ibogaine is not an authorized medicine, the quality of these products is not always known, increasing the probability of adverse reactions. Objective This study collects different types of iboga-derived samples from treatment providers, vendors and online buyers to analyse their content. Methods Analysis of iboga products (n = 16) was performed using gas chromatography and mass spectrometry methods (GC/MS). Products included Iboga root bark, Total Alkaloids (TA), Purified Total Alkaloids (PTA HCl), ibogaine hydrochloride (ibogaine HCl) and one Voacanga africana root bark. Results The content of ibogaine was highly variable, ranging from 0.6% to 11.2% for products sold as iboga root bark, from 8.2% to 32.9% for products sold as TA, 73.7% for one sample sold as PTA and from 61.5% to 73.4% for products sold as ibogaine HCl. One sample did not show any iboga alkaloids. Other alkaloids and unknown substances were found in almost all samples. Discussion The purity of iboga products is highly variable. These results should be taken into consideration by suppliers and users, especially regarding correct dosing to avoid overdose, as well as potential interactions with other substances.
Highlights
Ibogaine is a psychoactive alkaloid with hallucinogenic properties present in the root bark of Tabernanthe iboga, a tropical plant traditionally used in rites of passage and ethnomedicine in African countries such as Congo and Gabon[1]
The content of ibogaine was highly variable, ranging from 0.6% to 11.2% for products sold as iboga root bark, from 8.2% to 32.9% for products sold as Total Alkaloids (TA), 73.7% for one sample sold as purified total alkaloids (PTA) and from 61.5% to 73.4% for products sold as ibogaine HCl
Results show a large diversity of iboga alkaloid content in all the different products
Summary
Ibogaine is a psychoactive alkaloid with hallucinogenic properties present in the root bark of Tabernanthe iboga, a tropical plant traditionally used in rites of passage and ethnomedicine in African countries such as Congo and Gabon[1]. In 2008 it was estimated that 3,414 people used ibogaine, approximately a fourfold increase relative to the estimation of 857 from five years before[8] From those 3,414 subjects, 68% used ibogaine for the treatment of drug addiction. Results: The content of ibogaine was highly variable, ranging from 0.6% to 11.2% for products sold as iboga root bark, from 8.2% to 32.9% for products sold as TA, 73.7% for one sample sold as PTA and from 61.5% to 73.4% for products sold as ibogaine HCl. One sample did not show any iboga alkaloids. Discussion: The purity of iboga products is highly variable These results should be taken into consideration by suppliers and users, especially regarding correct dosing to avoid overdose, as well as potential interactions with other substances
