Details for Models of addiction

Authors: EMCDDA/Robert West

A better understanding of the complex science of ‘addiction’ can improve responses to drug problems. This report contains a critical review of existing addiction theories and explores how these can be organised into an overarching structure to inform how we assess, prevent and treat addictive behaviours. This model is not limited to illicit drugs, but can also be applied to alcohol, tobacco and even non-pharmacological addictions, such as gambling or compulsive use of the Internet.

Models of addiction delivers the message that understanding the biological basis of addiction, along with the broader social and psychological aspects of addictive behaviour, can lead to successful prevention and treatment responses.
