Addiction is a psychological and physical inability to stop consuming a chemical, drug, activity, or substance, even though it is causing psychological and physical harm. The term addiction does not only refer to dependence on substances such as heroin or cocaine. A person who cannot stop taking a particular drug or chemical has a substance dependence. Some addictions also involve an inability to stop partaking in activities, such as gambling, eating, or working. In these circumstances, a person has a behavioral addiction.
