On January 12, 2012, the fourth subject completed follow-up in our ongoing observational study of ibogaine treatment for addiction in Mexico. 22 out of 30 subjects are still in the follow-up portion of this study, which entails one year of evaluations of addiction and quality of life. The study’s final long-term follow-up visit is scheduled for September 2012. Data from this study will be compared with data from our soon-to-be-initiated observational ibogaine study in New Zealand.
