Federal baselineIn the United States, ibogaine is listed in Schedule I under federal controlled-substances law. The DEA controlled-substances schedule is the practical starting point for a federal status check; state rules and professional regulation can add further layers.
A Schedule I listing does not erase the possibility of tightly regulated scientific work, but it means research is subject to federal controls rather than being a general clinical pathway. The legal treatment of iboga-containing plant material, extracts, and purified alkaloid should be read against the precise wording of the applicable law and schedule.
