The long-term pattern of maladaptive behavior caused by the regular use of some chemical or drug is called:

• A. Hallucinosis
• B. Intoxication disorder
• C. Tolerance
• D. Substance use disorder

Answer: (D)

Think about how clinicians describe a persistent, maladaptive pattern of drug use that causes significant impairment or distress. That is substance use disorder. It captures ongoing problems such as continuing to use despite negative consequences, failing to meet responsibilities, cravings, and needing larger amounts or more time to achieve the same effect. It’s not about a single episode of intoxication, which would be a temporary state, nor about hallucinosis, which is a symptom that can occur under certain drugs. Tolerance is a physiological change that can occur with regular use, but by itself it does not define a long-term disorder. Substance use disorder best fits the idea of a long-term maladaptive pattern arising from regular use.
