What are they?
Opioids are a family of drugs that have morphine-like effects. Their primary medical use is to relieve pain. Other medical uses include control of coughs and diarrhea, and the treatment of addiction to other opioids. Opioids can also produce euphoria, making them prone to abuse.

Federal laws regulate the possession and distribution of all opioids. Penalties for the illicit possession and distribution of opioids range from fines to life imprisonment.
