Adolescent substance misuse : why one person may be more at risk than another, and what you can do to help / Ian Sutherland.

"This book contains questions that have been developed and tested by the author over a number of years that will help people to recognise that they - or someone they know - may either have an existing problem or are prone towards developing a problem.This is achieved through a "risk factor" or "odds ratio" approach which gives indicators of who might be particularly susceptible to substance abuse in different settings, and provides suggestions for changing the circumstances to help a young person avoid problems."--From synopsis.
