Nicotine causes inflammation in the arteries, which leads to narrowing and hardening of the blood vessels. When blood can't flow freely to your brain, you're at risk for blood clots, stroke and aneurysms. Nicotine also increases your endorphins, brain chemicals that make you feel good.
Nicotine, a key part of tobacco, is thought to relax the ring of muscle in the lower esophagus that keeps acid in the stomach, where it belongs. When that ring relaxes, acid can trickle up and cause that burning sensation. Smoking can also cause your mouth to make less spit, which might mean more heartburn symptoms.
