Does nicotine speed up your metabolism?

Answer

Findings published in the American Journal of Clinical Nutrition confirm that nicotine intake, even when isolated from cigarette smoking, significantly increases the resting metabolic rate in humans. The study found significantly higher increases in the resting metabolic rate of the nicotine intake group when compared to the placebo group.

The Nutrition & Metabolism journal states that nicotine has a psychostimulatory effect on the central nervous system when intake is at low levels. At higher levels, nicotine intake produces a calming, depressive effect. Nicotine use leads to increased heart rate via activation of the sympathoadrenal system. Nicotine has also been proven to improve learning, memory, reaction time and fine motor abilities in humans and in animals. The effects of nicotine have led to widespread abuse of the drug among athletes, who are likely to get nicotine from smokeless tobacco and other nicotine products rather than from cigarettes, which severely affect athletic endurance.
