Behavioural addictions like food, gambling, internet and sex can be just as debilitating as addiction to drugs or alcohol. It is well known that millions of people worldwide are addicted to alcohol and drugs. However, did you know that many also suffer from behavioural addiction? This is an addiction to processes, such as gambling, sex, internet-based activities and eating. It works on the brain in much the same way as a substance addiction, and can be just as powerful.
