Psychedelics also have the effect of making you neuroplastic again, something opiates take away. Ibogaine is not the only psychedelic that can be used for this purpose, psilocybin, dmt, lsd, mescaline, etc would be comparable to ibogaine. Being neuroplastic allows you to make new connections over the old ones that hardwire you to relapse that have become so strong during opiate usage.
