Non-substance related addictions - Compulsive behaviour
Some forms of addiction regard certain behaviours that are not related to substances. Furthermore, males and females tend towards different compulsive behaviours: Men are prone to compulsive gambling and sexual behaviour while women are addicted to shopping.
