MDMA-assisted therapy
MDMA therapy is a form of psychotherapy that utilizes small doses of the drug MDMA (Ecstasy or Molly) to help individuals with conditions such as PTSD, anxiety, and depression. The therapy typically involves the administration of 100 approx. 100 mg of MDMA (or simular drugs) during a therapy session. The goal of the therapy is to help individuals process and integrate traumatic experiences and to reduce symptoms of PTSD, anxiety, and depression. This type of therapy is still under research and it is not yet widely available, and is considered illegal in most countries. In the Netherlands it's possible do MDMA therapy with a drug that's almost the same as MDMA but works even better for therapy.
