The definition of addiction is ambiguous, but it simply refers to a state in which an individual exhibits compulsive, out-of-control behavior and an inability to self-control (Philibin & Crabbe, 2015). In addiction, the out-of-control behavior is related to the substance’s use despite the negative consequences (Philibin & Crabbe, 2015).
