Despite the prevalence of addiction in our society, we remain remarkably ignorant of the effects of addictive behaviour in classrooms - and unprepared to deal with the consequences. The authors of this book combine their own experiences of family and individual addictions with research to provide an accessible resource for understanding and dealing effectively with addiction. Classrooms Under the Influence provides suggestions for developing a classroom plan for assessing, intervening and preventing inappropriate behaviours for both addicted students and those who live with addicts. Readers are also encouraged to identify ways in which their own addictive behaviours may have a negative impact on the health and productivity of classrooms.
