An addiction is a disorder characterized by the compulsive use of a rewarding substance or activity despite experiencing adverse consequences. This complex condition is influenced by a person’s genes and their environment and is often considered a brain disease.

In the past, addiction was thought to only encompass substance abuse, but the definition has been expanded to include activities like gambling as well as gaming, sex and shopping. It’s also important to note that addiction is about the underlying neurology of the brain and not about the outward behaviors. With appropriate treatment, people with addictions can go on to live happy, healthy lives.
