Brazil is a country with increasing rates of violence. Violence is associated with mental health disorders such as PTSD, for which a range of 1.3 to 4.9 percent of the population qualifies due to events such as sexual abuse or similar molestations. In this regard, a selected sample that qualified for PTSD diagnoses and reported being victims of sexual abuse underwent a set of MDMA interventions to understand the clinical effects of the drug in terms of the relief of PTSD symptomatology.
