Psychedelic drugs such as MDMA and psilocybin, the hallucinogenic compound found in magic mushrooms, have promised to revolutionize psychiatric treatments. Now, a small trial in military veterans suggests that a lesser-known, potent psychedelic drug called ibogaine could be used to treat traumatic brain injury (TBI). One month after ibogaine treatment, the veterans reported that TBI symptoms such as post-traumatic stress disorder (PTSD) and depression had decreased by more than 80%, on average¹.

“The drug seems to have a broad, dramatic and consistent effect,” says Nolan Williams, a neuroscientist at Stanford University in California and a co-author of the study. The results of the trial, which did not include a control group, are published today in Nature Medicine.

These data support launching rigorous trials to test the drug, says Alan Davis, a clinical psychologist at the Ohio State University in Columbus. However, they note that MDMA and psilocybin, which are already in late-stage trials, will be “much better candidates for meeting the needs of this community”. Ibogaine will require years of study to determine its efficacy and safety, Davis says.
