What can be a physical consequence of inhalant use?

Drowsiness is a common physical consequence of inhalant use due to the depressant effects that many inhalants have on the central nervous system. Inhalants work by quickly reaching the brain, leading to a range of short-term effects that can include euphoria, dizziness, and drowsiness. As the body processes these substances, individuals may experience sedation and lethargy, contributing to impaired motor skills and decreased cognitive function.

The other options reflect effects that are not typically associated with inhalant use. Improved reaction time and enhanced cardiovascular fitness suggest increased physical performance and responsiveness, which are unlikely in the context of inhalant intoxication. Similarly, increased alertness contradicts the sedative properties of most inhalants, which often lead to drowsiness and decreased overall energy levels. Therefore, drowsiness accurately represents one of the physical consequences of inhalant use.
