Substance Abuse (in Adolescents)

Scoring Key
A score of 2 or more positive answers means that you should speak with your doctor, or a health professional.

The questionnaire used here is the 6-item CRAFFT, developed by Dr. John Knight of the Center for Adolescent Substance Abuse Research at Children's Hospital, Boston, USA.
