Ibogaine was listed on the French pharmaceutical formulary as a medication for approximately 36 years between the 1930s and 1966.

"why did the French think this was helpful for 36? ... to have a drug on the formulary for 36 years that, you know, wasn't doing anything for the French, it seems unlikely-- it's possible, but unlikely-- that that would have stuck around and been sold for 36 years." (said at 0:58:11)

Follow-up data out to one year in special forces veterans treated with ibogaine shows that most participants maintain their clinical improvements.

"So we have data out to a year. It isn't published yet. It's kind of in review now, actually, and uh that looks really good. Uh most people hold it." (said at 1:05:45)

No published record matching one-year follow-up clinical outcome data for ibogaine treatment in Special Operations Forces veterans was located; this does not prove the claim false, as the speaker noted the one-year data was unpublished and under review. Published prospective observational studies in this population have reported significant improvements in functional disability, PTSD, depression, anxiety, and alcohol misuse maintained up to 1 month (Williams et al., Nature Medicine 2024) and 6 months (Davis et al., 2023, 2024) post-treatment.
