Preliminary evidence suggests that the combination of magnesium and ibogaine, an atypical psychedelic, may be a promising treatment for post-traumatic stress disorder (PTSD), opioid use disorder, and traumatic brain injury (TBI). The "mystical" experience elicited by ibogaine, which is characterized by feelings of awe, selflessness, and transcendence, is correlated with improvements in PTSD...

Cortical thickness analysis revealed post-treatment increases in 11 regions. Subcortical analyses revealed significant volumetric expansion in 8 regions. Magnesium-ibogaine therapy was...
