Which of the following is a potential symptom of inhalant use?

A flushed face is a potential symptom of inhalant use due to the various substances individuals may inhale, which can cause blood vessels to dilate and lead to increased blood flow to the skin. This physiological reaction can result in noticeable redness or warmth in the face. Inhalants often depress the central nervous system, leading to altered states of consciousness, which can also cause specific physical reactions like a flushed appearance.

In contrast, increased weight is not directly associated with inhalant use, as these substances may actually lead to weight loss due to decreased appetite and other health effects. Heightened alertness is typically linked to stimulants rather than inhalants, which usually have sedative effects. Clear speech would be unlikely in cases of inhalant use, as these substances often impair cognitive function and coordination, leading to slurred or unclear speech patterns.
