Ibogaine is unfortunately classified as a schedule 1 substance in the US, despite its promising clinical applications. Wikipedia has a great chart showing its status by country: https://en.wikipedia.org/wiki/Legal_status_of_ibogaine_by_country

Two cautionary notes when seeking ibogaine: it is one of the riskier psychedelics to take, especially if there are underlying cardiac conditions - though the clinical research is not as robust yet as with some other compounds. We recommend that it is only done with careful consultation with your physician and a clear-eyed view of the personal health risks.

We would also recommend confirming that the sourcing of the iboga is done in an environmentally sustainable way, as increasing mainstream demand for ibogaine has resulted in unfettered deforestation that threatens the long term viability of ibogaine as a treatment option.
