Opioid use disorder is a pattern of opioid use marked by strong cravings, continued use despite worsening physical or psychological harm, increasing tolerance, and withdrawal symptoms after stopping. Withdrawal can include nausea, muscle aches, diarrhea, difficulty sleeping, agitation, and low mood. Both addiction, the compulsive drive to use despite harm, and physical dependence, the body's adaptation to regular exposure, are components of the disorder, though they are conceptually distinct.
