Which symptom is NOT a sign of methamphetamine use?

Weight gain is not considered a sign of methamphetamine use. Methamphetamine is a powerful stimulant that typically suppresses appetite and increases energy levels, often leading to weight loss rather than weight gain. Individuals using meth may experience a variety of other symptoms, such as dilated pupils, agitation, and increased blood pressure, as the drug stimulates the central nervous system and alters normal physiological responses.

In contrast, dilated pupils and increased blood pressure are direct physical manifestations of the stimulant effects of methamphetamine. Agitation is a common behavioral response, as individuals may exhibit hyperactivity, restlessness, or aggressive behavior due to the intense stimulation caused by the drug.
