opiates

In medicine, the term opiate describes any of the opioid analgesic alkaloids found as natural products in the opium poppy plant, Papaver somniferum. The term opiate is often incorrectly used to describe all drugs with opium- or morphine-like pharmacological action, which are more properly classified under the broader term opioid. Semi-synthetic opioids such as hydrocodone, hydromorphone, oxycodone, and oxymorphone, while derived from opiates, are not opiates themselves.
