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 itself is not especially harmful, apart from being an addictive drug. However, the chemicals associated with nicotine intake, whether smoking or smokeless, cause a variety of diseases including lung cancer, mouth cancer, heart disease, emphysema and chronic obstructive pulmonary disease (COPD). 9 people found this useful.
