Addiction is a condition that results when a person ingests a substance (e.g., alcohol, cocaine, nicotine) or engages in an activity (e.g., gambling, sex, shopping) that can be pleasurable but the continuation of which becomes compulsive and interferes with ordinary responsibilities and concerns, such as work, relationships, or health.
Dopamine is indeed involved in addiction, but it isn't a pleasure chemical. In fact, dopamine has lots of functions in the brain â being involved in everything from regulating movement to the control of attention. In great part, its effects depend on which of the brain's pathways it is operating in.
