What is drug dependence?
Drug dependence is a pattern of repeated drug taking that usually results in tolerance (the need for greater amounts of the drug to achieve the same effect), withdrawal (physical and cognitive effects when drug use declines or stops), and compulsive drug taking behaviour (drug taking that persists despite efforts to reduce intake and despite problems with family, friends and work).
Drug dependence is a complex problem. It encompasses a diverse range of drugs (such as alcohol, cannabis, amphetamines and cocaine) and is caused by many different factors.
Drug problems are frequently accompanied by other psychological problems such as behavioural disorders, depression, anxiety, and eating disorders. These co-occurring psychological problems must be addressed when seeking treatment for drug dependence as they may interfere with the effectiveness of treatment.
