Which comorbid conditions are common with substance use disorders?

• A. Seasonal allergies
• B. Depression, anxiety disorders, PTSD, chronic pain, hepatitis C, HIV, sleep disorders
• C. None of the above
• D. Diabetes, hypertension, hyperlipidemia, obesity

Answer: (B)

Substance use disorders most often occur alongside other mental health conditions and certain medical problems, so recognizing these co-occurring issues is essential for effective care. Depression, anxiety disorders, and PTSD are common because people may use substances to cope with distress, and there are overlapping neurobiological factors that heighten vulnerability to both substance use and mood or anxiety symptoms. Chronic pain is frequently seen as a comorbidity, since ongoing pain can lead to self-medication with substances, and substance use can worsen pain perception and management. Infections like hepatitis C and HIV appear with higher frequency in this population, particularly when risky behaviors or injection drug use are involved, making screening and linked medical care important. Sleep disorders also commonly accompany substance use, contributing to a cycle that can drive ongoing use and impair recovery.

The other options don’t fit the typical pattern as well. Seasonal allergies aren’t a characteristic comorbidity tied to substance use disorders in a way that informs treatment. While metabolic conditions such as diabetes, hypertension, hyperlipidemia, and obesity can occur in people with substance use issues, they are not as specifically or consistently linked to SUDs as the combination listed here.
