Symptoms of opioid abuse can be categorized by physical state.

Intoxication state

Patients with opioid use disorders frequently relapse and present with intoxication. Symptoms vary according to level of intoxication. For mild to moderate intoxication, individuals may present with drowsiness, pupillary constriction, and slurred speech. For severe overdose, patients may experience respiratory depression, stupor, and coma. A severe overdose may be fatal.
