“Addiction” is a brain disorder, characterized by compulsive engagement in rewarding stimuli, despite adverse consequences. The two properties that characterize all addictive stimuli are that they are reinforcing (i.e., they increase the likelihood that a person will seek repeated exposure to them) and intrinsically rewarding (i.e., they are perceived as being inherently positive, desirable, and pleasurable). Addiction exacts a high toll on individuals and society as a whole, through the direct adverse effects of drugs, associated healthcare costs, long-term complications (e.g., lung cancer with smoking, liver cirrhosis with drinking alcohol or “methmouth” from intravenous methamphetamine), and the consequent loss of productivity. Classic hallmarks of addiction include impaired control over substances or behaviour, preoccupation with substance or behaviour, and continued use despite consequences. Habits and patterns associated with addiction are typically characterized by immediate gratification (short-term reward), coupled with delayed deleterious effects (long-term costs).
