A named veteran will go to Capitol Hill — either in person or via recorded video testimony — and tell members of Congress that ibogaine treated their PTSD, substance use, or both. Congress will hold a formal hearing or briefing. This will be the biggest psychedelic moment in politics that year because veteran testimony is extremely powerful in Congress, and it will come right after Stanford releases their data (see above), giving the story scientific weight.
Veteran testimony is the psychedelic reform coalition's most deployable political asset, and Stanford data release (see above) gives advocates the scientific cover needed to schedule a hearing. 'Highest-profile' is resolvable by media coverage metrics and C-SPAN viewership data vs. prior psychedelic hearings. Falsifiable: either a named veteran testifies before Congress about ibogaine by August 31 or they do not.
