  • Traumatic experiences are associated with substance use and with developing substance use disorders. Violence, abuse, neglect, and family or social conflict are among the traumatic events and circumstances that are linked with the risk of developing a substance use disorder.
  • Children and adolescents who experience trauma are particularly susceptible to developing a substance use disorder later in life. Many people who have been diagnosed with post-traumatic stress disorder (PTSD) also have a substance use disorder.
  • There are effective treatments for trauma-related mental health disorders. NIDA supports research to better understand the impact of trauma and chronic stress on the risk of developing a substance use disorder, and on how to prevent that outcome.
