Which statement best describes the condition under which screening for unhealthy drug use should be implemented?

• A. When patient requests screening
• B. When laboratory tests are readily available
• C. When there is strong patient demand
• D. When services for accurate diagnosis, effective treatment, and appropriate care can be offered or referred

Answer: (D)

Screening for unhealthy drug use should be implemented only when there are resources to provide or arrange accurate diagnosis, effective treatment, and appropriate care for those who screen positive. The value of screening comes from the ability to connect people with real treatment and supportive services; without a clear path to care, identifying issues offers little benefit and can cause more harm through anxiety, stigma, or unnecessary testing. That’s why simply having patient requests, laboratory tests, or strong demand isn’t enough on its own—the essential condition is the availability of diagnosis and treatment options or referrals.
