Understanding Addiction
Some definitions of addiction focus on the physical aspects, like cravings or withdrawal symptoms when you stop using. Other definitions include habits, behaviours or the consequences of overusing a substance. Usually, you have an addiction if you are unusually dependent on something that is physically or psychologically habit-forming.
Generally, when you continue to use a problem substance (such as drugs or alcohol) or engage in a problem behavior (such as gambling)—despite its disruptive effects on your life and your loved ones—it is likely that you have an addiction.
