On April 27, 2014, the 14th and final subject was enrolled in our nearly completed New Zealand observational study of ibogaine assisted treatment for opioid dependence. Since July 2012, Principal Investigator Geoff Noller, Ph.D., has been collecting follow-up data from subjects undergoing treatment at an independent ibogaine center in New Zealand. Eight participants have completed the study including the long-term follow-up. Data from this study will be compared to the results of our completed observational study in Mexico.
