What is NOT a symptom of nicotine intoxication?

Bradycardia is not a symptom of nicotine intoxication. In fact, nicotine typically causes an increase in heart rate, a phenomenon known as tachycardia. When a person experiences nicotine intoxication, symptoms may include heightened anxiety, insomnia due to stimulation, and increased gastrointestinal motility, which can lead to symptoms like nausea and diarrhea. Nicotine stimulates the release of adrenaline, which increases heart rate and can contribute to anxiety and restlessness, while also affecting the digestive system by enhancing motility. Therefore, recognizing that bradycardia does not align with the physiological responses associated with nicotine intoxication aids in understanding the drug's stimulating effects.
