Which symptom is typically NOT related to tobacco intoxication?

In the context of tobacco intoxication, increased libido is typically not a symptom associated with its use. Tobacco primarily contains nicotine, which acts as a stimulant in the central nervous system. While nicotine can cause various physiological responses such as increased heart rate, blood pressure, and potential heightened alertness, it does not directly correlate with an increase in sexual desire or libido.

On the other hand, symptoms like sweating, respiratory failure, and vomiting can occur with nicotine intoxication or overconsumption. Sweating is a common physiological response to nicotine, as it can elevate metabolic activity. Respiratory failure can happen in extreme cases of nicotine poisoning, especially if it leads to central nervous system depression and impaired respiratory function. Vomiting can also occur due to nicotine's emetic properties, particularly with high doses or in novice users.

Thus, while nicotine affects multiple bodily systems, the increase in libido is not a recognized symptom of tobacco intoxication, making it the correct choice in this scenario.
