“Addiction is any repeated behavior, 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: 1. Compulsive engagement with the behavior, a preoccupation with it 2. Impaired control over the behavior 3. Persistence or relapse despite evidence of harm 4. Dissatisfaction, irritability, or intense craving when the object—whether it be a drug, activity, or other goal—is not immediately available.”
