Objective
The student will learn how opiates produce an analgesic effect.
Activity
Note that opiates are powerful painkillers and are used medically for treatment of pain. When used properly for medical purposes, opiates do not produce an intense feeling of pleasure, and patients have little chance of becoming addicted. Have students search the Internet and other sources for information about pain, pain control, and the way opiates produce their analgesic effect and then prepare a brief summary report.
