Which of the following is NOT one of the four categories of symptoms for Substance Use Disorders?

Substance Use Disorders are characterized by a range of symptoms grouped into four main categories: impaired control, social impairment, risky use, and pharmacological criteria. The category of "emotional regulation" does not belong to the recognized classification of symptoms. While emotional regulation issues can accompany substance use and may be affected by substance use disorders, they are not specifically categorized as a primary symptom of the disorder itself.

Impaired control refers to the inability to reduce or control substance use despite a desire to do so. Social impairment highlights the negative impact substance use has on social and interpersonal relationships. Pharmacological withdrawal involves experiencing withdrawal symptoms when not using the substance, indicating a physiological dependence on it.

Thus, "emotional regulation" is not one of the formal categories recognized in the diagnosis of Substance Use Disorders, making it the correct choice for this question.
