Which of the following is NOT a sign of cocaine use?

Weight gain is not a sign typically associated with cocaine use. Cocaine is a stimulant that generally suppresses appetite and increases metabolic activity, often leading to weight loss rather than gain. Users may experience increased energy levels and decreased need for food, which contributes to weight loss over time.

In contrast, dilated pupils are a common physiological response during cocaine intoxication, as the drug stimulates the sympathetic nervous system. Nausea and vomiting can also occur, particularly during withdrawal or if a person has ingested a large amount of the substance. Rapid motor movement is another characteristic of cocaine use, reflecting increased energy and restlessness due to the stimulating effects of the drug. These signs are well documented in the context of cocaine's effects on the body and mind.
