Definition of opiate
(Entry 1 of 2)
Note: The use of opiate for substances that bind to opiate receptors but are not opium derivatives is often considered technically incorrect. Such substances are more commonly referred to as opioids. The word opioid itself was originally used only for these substances, but it has now become widely accepted as a broader term encompassing any substance—natural, synthetic, opium-derived or not—that binds to opiate receptors and has morphine-like activity.
