Noribogaine
Noribogaine, or 12-hydroxyibogamine, is the principal psychoactive metabolite of the hallucinogenic drug ibogaine. It is thought to be involved in the antiaddictive effects of ibogaine-containing plant extracts, such as Tabernanthe iboga.
A recent study evaluated its effects on healthy volunteers at doses of 3–60 mg, finding no tolerability issues. A slow half-life of 28–49 hours was seen with large volume of distribution.
