Data from the National Survey of Adolescents  (PDF) and other studies indicate that one in four children and adolescents in the United States experience at least one potentially traumatic event before the age of 16, and more than 13% of 17-year-olds—one in eight—have experienced posttraumatic stress disorder (PTSD) at some point in their lives.
Many of these young people also have access to psychoactive substances that can both dull the effects of stress and place teens at increased risk of experiencing trauma. It is estimated that 29% of adolescents—nearly one in three—have experimented with illegal drugs by the time they complete eighth grade, and that 41% have consumed alcohol.
The NCTSN has developed tools and materials to help mental health clinicians, substance abuse treatment providers, parents, caregivers, and youth address the complex needs of this population.
