What symptom may indicate a severe substance use disorder?

• A. Increased social interaction
• B. Withdrawal symptoms when not using substances
• C. Enhanced productivity at work
• D. Greater interest in hobbies

Answer: (B)

Withdrawal symptoms when not using substances is a significant indicator of a severe substance use disorder. This symptom arises when an individual develops a physical or psychological dependence on a substance. When they reduce or stop using the substance, they may experience various physical and mental health symptoms, which can include anxiety, irritability, nausea, tremors, and seizures, depending on the substance involved. The presence of withdrawal symptoms suggests that the body has adapted to the substance, resulting in a physiological need for it to function normally.

In contrast, increased social interaction, enhanced productivity at work, and greater interest in hobbies do not correlate with substance use disorders. These behaviors may indicate healthier coping mechanisms or changes in lifestyle and do not reflect dependence or the adverse consequences associated with substance use. Therefore, the presence of withdrawal symptoms serves as a clear marker for a severe substance use disorder, highlighting the need for intervention and support.
