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.
It constricts blood vessels to help relieve allergy symptoms and headache, hence its inclusion in many over-the-counter medications.
