Addiction refers to a difficulty in controlling certain repetitive behaviours to the extent that they have harmful consequences. They are the result of powerful compulsions to use and do certain things excessively, often out of a need to escape from upsetting emotions/situations. These compulsions can trigger a self-perpetuating process, which can cause pain and suffering not only for those addicted, but also for their friends and family.
Addiction treatment such as counselling is crucial for helping sufferers to recognise their condition and how their emotional needs are affecting their behaviour. This can be an important step on the road to recovery and, eventually abstinence.
