Which symptom is commonly found in opioid intoxication?

Opioid intoxication is characterized by a distinct set of symptoms that stem from the effects of opioids on the central nervous system. One of the hallmark signs of opioid intoxication is slurred speech, which arises due to the sedative effects of these substances. Opioids have a depressant effect, leading to slowed cognitive and motor functions, which manifest as difficulty in speech articulation.

In contrast to slurred speech, symptoms such as agitation and increased energy are generally not associated with opioid use. Agitation is more typical in stimulant intoxication, while increased energy is antithetical to the sedative properties of opioids, which typically result in drowsiness or lethargy. Hallucinations can occur with certain substances but are not a common symptom of opioid intoxication; rather, they may be associated with other classes of drugs or in cases of severe intoxication or withdrawal effects. Thus, slurred speech stands out as a key indicator of opioid intoxication.
