I've been assuming it was some sort of profit motive as TX has been pumping money into it. It seems like there might actually be science driven though. For tramatic brain injury combined with ptsd ibogaine causes a release of glial cell factors that help neuroplasticity wire around the damage. Its also horribly unsafe from a cardiac perspective so you would need a constant eeg during therapy driving up prices. So probably a little of the original motivation too.

Or DMT. I also question how they derive the consclusion of a "horrible heart risk". Imo there is not enough evidence for that.
