MDMA and Psilocybin have shown fantastic efficacy. Look up MAPS Trial for efficacy data, it's about as close to a magic pill for PTSD as one can imagine.

"MDMA was found to induce significant and robust attenuation in CAPS-5 score compared with placebo (P < 0.0001, d = 0.91) and to significantly decrease the SDS total score (P = 0.0116, d = 0.43)."

A p-value of 0.0001 is extremely good. [1] https://www.nature.com/articles/s41591-021-01336-3
