The most common medical use for opiates is to relieve pain.
Opiates work by altering the way that pain is perceived. They mimic chemicals in your brain and body that attach to tiny parts on neve cells called opioid receptors. These receptors play different roles, but they are generally responsible for the pleasurable effects from opiates and their ability to reduce pain.
