Addiction is any repeated behaviour, substance-related or not, in which a person feels compelled to persist, regardless of its negative impact on his life and the lives of others. Addiction involves: compulsive engagement with the behaviour, a preoccupation with it; impaired control over the behaviour; persistence or relapse, despite evidence of harm; and dissatisfaction, irritability or intense craving when the object—be it a drug, activity or other goal—is not immediately available.
Many people experience addictive behaviours in their lives—either through their own or coming into contact with the addictive behaviour of friends, acquaintances, and loved ones. The impact varies depending on the nature of the addiction.
Addictive behaviours can powerfully impact: relationships with others; job performance; financial stability; feeling of self worth; physical, emotional, and spiritual health and general quality of life from day to day.
