Check out the psychology databases. In particular:

  • PsycARTICLES
  • PsycINFO
  • Academic Search Complete
  • Wiley Online Library
  • OmniFile

Vary up your search terms a little so they include PTSD and Post-Traumatic Stress Disorder and any other synonyms. For MDMA you can also use 3,4‐methylenedioxymethylamphetamine or ecstasy.
