Which behavioral disorder is classified under Substance Use Disorders (SUD) in the DSM?

Gambling disorder is classified under Substance Use Disorders (SUD) in the DSM because it meets the criteria for a behavioral addiction, sharing similar features with substance use disorders. It is characterized by persistent and recurrent problematic gambling behavior that leads to significant clinical impairment or distress. The DSM recognizes it as a condition where individuals experience a loss of control, cravings, and continued engagement despite negative consequences, resembling the patterns seen in disorders associated with substance use.

In contrast, internet gaming disorder is currently classified as a condition warranting further study, and while smoking has historically been associated with substance use, nicotine dependence is specifically classified under substance use disorders rather than a behavioral disorder. Compulsive shopping disorder, while it may involve addictive behaviors, is not recognized in the same way as gambling disorder or other behavioral addictions within the DSM framework, which is why it does not fall under the category of Substance Use Disorders.
