Is it possible for nicotin from smoke to produce energy in your body?

Nicotine, a colorless and addictive alkaloid found in tobacco plants, primarily acts as a stimulant in the body, affecting the nervous system and brain. While it does not directly produce energy in the way some nutrients or fuel sources do, it can lead to an elevation in heart rate and blood pressure. These physiological responses can create a perception of increased alertness and energy, but nicotine itself is not a direct energy source for the body.
