As drug use increases, it becomes increasingly more difficult to keep life under control. The loss of control may result in desperate actions to maintain normal appearances. These desperate actions define addictive behaviour and include lying; stealing; lack of responsibility (at work and home); lack of reliability (late for appointments, breaking promises); carelessness with health and hygiene; impulsiveness; obsession and/or compulsion; poor work habits; loss of interest in family life, recreation and hobbies; isolation; using other drugs, alcohol or prescribed medication; stopping prescribed medication; loss of self-control; and loss of ability to cope with everyday problems.
