From Wikipedia: "Anecdotal reports concerning ibogaine's effects appeared in the early 1960s. [...] In 1992, Eric Taub brought ibogaine to an offshore location close to the United States, where he began providing treatments and popularizing its use.

Data demonstrating ibogaine's efficacy in attenuating opioid withdrawal in drug-dependent human subjects was published by Alper et al. in 1999.
