CRAFFT Questionnaire for Adolescent Substance Abuse

Description

Calculates the CRAFFT screening score to identify substance use problems in adolescents (age 12-21). The tool consists of three opening questions regarding use of alcohol, marijuana, or other drugs in the past 12 months. If any are positive, six further questions (Car, Relax, Alone, Forget, Friends, Trouble) are asked. If the opening questions are negative, only the 'Car' question is asked.
