Which of the following would NOT typically be included in signs of drug impairment?

Increased alertness is not typically associated with drug impairment because drug use often results in decreased cognitive functions, confusion, or drowsiness, rather than heightened awareness. Impairment from substances can lead to a range of negative effects on a person's motor skills and mental acuity. Signs like slurred speech, impaired coordination, and unsteady movements are common indicators of drug impairment, as they reflect the impact of substances on the nervous system and the ability to perform tasks that require fine motor skills and clear communication. Therefore, increased alertness stands out as a characteristic that is generally not linked to impairment, making it the correct choice in this context.
