Opiate

Opiates are analgesic alkaloid compounds found naturally in the opium poppy plant Papaver somniferum.

The psychoactive compounds found in the opium plant include morphine, codeine, and thebaine. The term opiate should be differentiated from the broader term opioid, which includes all drugs with opium-like effects, including opiates, semi-synthetic opioids derived from morphine (such as heroin, hydrocodone, hydromorphone, oxycodone, and oxymorphone), and synthetic opioids which are not derived from morphine (such as fentanyl, buprenorphine, and methadone). All opioids, including the opiates, are considered drugs of high abuse potential and are listed under the Controlled Substances Act.

In 2013 between 13 and 20 million people used opiates recreationally (0.3% to 0.4% of the global population between the ages of 15 and 65).
