Addiction is a chronic, progressive but treatable disorder in which someone becomes dependent on a substance or behavior that’s psychologically or physically dangerous and habit-forming. Addiction causes a person to act compulsively and experience a lack of control. Without treatment or changing behavior (such as moving toward recovery) the condition worsens over time. Addictions can range from drug addiction and alcoholism to compulsive gambling and addictions to food, sex and technology/Internet. Signs of an addiction include an inability to stop using despite negative consequences; developing a tolerance coupled with experiencing withdrawal symptoms; avoidance of activities that were once enjoyable and behavioral changes such as increased irritability or paranoia. Addiction is typically treated through a combination of cognitive behavioral therapy, treatment centers or rehab, group therapy, one-on-one counseling, social support groups and/or medication.
