Opioid detox is what built the ibogaine industry. Patients report that a single flood dose dramatically reduces acute withdrawal, which is what makes ibogaine unlike every other detox approach, and it is the primary program at most Mexican clinics. Fentanyl has changed the picture: because it is long-acting in tissue, most clinics now require longer stays, pre-treatment stabilization, and stricter screening for fentanyl cases. Methadone and Suboxone are the hardest detoxes, typically requiring 21 to 30 day programs.
Two cautions belong next to the promise. First, the evidence base is mostly observational; controlled trials are only now being funded, including the Texas IMPACT trial. Second, the mortality data concentrates in exactly this population: opioid-dependent patients carry the cardiac risk, so the medical tier of clinic is non-negotiable for detox cases. Relapse after treatment is also common without aftercare, and tolerance resets, which makes early relapse unusually dangerous.
