Description
Opioids are a class of drugs that include prescription pain relievers (e.g., oxycodone, hydrocodone, morphine), synthetic opioids (e.g., fentanyl), and illegal drugs (e.g., heroin). Opioid Use Disorder is a problematic pattern of opioid use leading to clinically significant impairment or distress. Intoxication involves recent opioid use resulting in characteristic behavioral and physical signs, while withdrawal is a predictable syndrome that occurs after stopping or reducing prolonged use.
