At the end of the chapter, you should ask yourself the following questions:

• Can I explain the diagnostic criteria for substance use disorders?
• Could I explain why any account of substance use disorder has to strike a delicate balance between ‘choice’ and a loss of control/compulsion?
• Can I critically evaluate the importance of brain adaptations and cognitive processes in substance use disorders?
• Can I explain why some people are at greater risk of developing substance use disorders than others?
• Do I understand how substance use disorders are treated, and can I relate these treatments back to their theoretical models?
