What might suggest that an individual is under the influence of drugs or alcohol?

An individual appearing nervous or agitated can be a significant indicator that they may be under the influence of drugs or alcohol. The consumption of substances can often alter a person's emotional state, leading to behaviors that are atypical for them. Agitation might manifest as restlessness, rapid movements, or an inability to sit still, while nervousness could present as fidgeting, avoiding eye contact, or speech that is disjointed or erratic. These signs are often observed in individuals who are under the influence, as substances can impair judgment and provoke anxiety or paranoia.

In contrast, making eye contact, being cooperative, and engaging in conversation do not inherently suggest impairment. In fact, these behaviors could indicate that a person is functioning normally or even trying to present themselves in a socially acceptable manner. Understanding these cues is essential for peace officers when assessing individuals during stops or interventions.
