"The medical treatment model presently exists mainly in countries adjacent to the US, such as Mexico, where ibogaine is subsumed within a physician’s legal prerogative to prescribe experimental treatment, or Saint Kitts, where the government includes ibogaine in its national formulary and provides specific approval to the clinic there to administer it. The most common setting is a private clinic with less frequent use of hospitals."
