New CED – Sleep And Drugs Practice Test

Which term describes a drug that depresses neural activity and reduces pain and anxiety?

Stimulants Consciousness Psychoactive Drugs Opioids

Correct Answer:

Opioids

Explanation:

Opioids are drugs that slow down brain activity and provide analgesia and anxiolysis. They bind to opioid receptors in the brain and spinal cord, dampening pain signal transmission and often producing sedation and a sense of calm, which reduces anxiety. This combination—the depression of neural activity along with pain relief and calming effects—fits opioids, unlike stimulants (which boost activity), conscious states (not a drug), or the broad psychoactive category (which includes drugs that can increase or decrease activity). Examples include morphine, codeine, heroin, and prescription opioids like oxycodone and fentanyl.
