Which symptom is not common for people under the influence of cocaine?

People under the influence of cocaine often experience a range of stimulating effects due to its mechanism as a central nervous system stimulant. Symptoms frequently include dilated pupils, elevated blood pressure, and in some cases, vomiting, which can occur due to the drug's impact on the gastrointestinal system and central nervous system.

Dilated pupils result from the sympathetic stimulation caused by cocaine. Elevated blood pressure is a common cardiovascular response, as cocaine increases cardiac output and systemic vascular resistance. Vomiting can occur as well, though it is less consistent, particularly in acute use scenarios.

Inability to walk is not a typical symptom associated with cocaine use. While cocaine can lead to increased energy and hyperactivity, it does not usually cause the type of motor impairment that would prevent someone from walking. This symptom is more representative of depressant substances or severe intoxication with other drugs that significantly alter motor function. Thus, the inability to walk stands out as an uncommon symptom for individuals under the influence of cocaine.
