An addictive behavior is a behavior, or a stimulus related to a behavior (e.g., sex or food), that is both rewarding and reinforcing, and is associated with the development of an addiction. Apart from the aforementioned addictive behaviors the most common one would be substance addiction (including alcohol, tobacco, drugs and cannabis). There is a medical model which perceives addictive behavior as a disease that is caused by uncontrollable and recessive drug use overtimes and the addict barely has control of it. The other view is from the moral standpoint which regards addictive behavior as an intentional choice was freely made by the addict. Addictions involving addictive behaviors are normally referred to as behavioral addictions.
