An opiate is a substance derived from the poppy plant (which contains opium). Opiates are sometimes called natural since the active ingredient molecules are made by nature, not manufactured by chemical synthesis. Common opiates include morphine and codeine, both made directly from poppy plants. An opioid is a substance (molecule) that is synthetic or partly synthetic, meaning the active ingredients (molecules) are manufactured via chemical synthesis.
Opioids are derivatives of morphine, a narcotic pain reliever. The term opioid generally refers to morphine and other opium poppy-based medications. Opioids work by decreasing pain signals being transmitted through the nervous system, which suppresses our perception of pain.
