New Zealand's regulatory body, Medsafe, has authorized the use of medical-grade MDMA to treat patients suffering from severe PTSD. This move makes New Zealand the second nation to permit this, following Australia's decision in 2023. Under the new rules, a pair of psychiatrists are authorized to prescribe MDMA-assisted therapy to adults 18 and older. The treatment must be administered within a supervised clinical environment combined with psychotherapy, and patients are not permitted to take the medication home.
