Abstract From the Canadian patent

The administration to a heroin addict of ibogaine ibogaine HCl or other non toxic salts of ibogaine an, alkaloid of the family apocynaceae has been discovered to, unexpectedly interrupt the physiological and psychological aspect of the opiate addiction syndrome. A single treatment was effective for about 6 months, and a series of 4 treatments was effective for approximately 3 years. The treatments consisted of the oral administration of ibogaine or its salts in dosage ranges of 6 mg/kg to 19 mg/kg. The minimum effective dose was 400 mgs and dosage increases above 1000 mgs were found to be unnecessary. Treatments were effective in 71% of the cases.
