Human and animal studies suggest that IC-26 is around the same potency as methadone,[3][4] although other studies have found its activity to be inconsistent between different patients, with consistent opioid activity only being seen at a dose several times that of methadone. IC-26 was assessed for its abuse potential, but despite being found to have similar potential to methadone for development of dependence[5] it was never placed under international control as an illegal drug.
