How do opiates suppress pain?
What will be an ideal response?
The chemical properties of opiates are similar to endorphins. These drugs mimic the body's own natural painkillers, the endorphins (which naturally suppress pain). Of note, opiates affect parts of the brain other than the "reward centers" involved in pleasure. Opiates, while potentially causing euphoria, don't affect dopamine in the pleasure centers of the brain as does cocaine or amphetamines.
