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.
NEW ORLEANS â Even smokeless cigarettes may cause damage that can lead to hardening of the arteries, a new study implies. Vascular smooth muscle cells wrap around blood vessels and help control blood flow and pressure.But inflammation and chemicals, such as those found in cigarette smoke, can turn the cells into miniature drills that chew through connective tissue, allowing muscle cells to burrow into blood vessels.Once inside, the cells and other debris clump into artery-clogging plaques.Nicotine is one chemical that helps turn normal muscle cells into invaders, Chi-Ming Hai, a physiologist at Brown University in Providence, R.I., reported December 15 at the American Society for Cell Biologyâs annual meeting.ascular smooth muscle cells wrap around blood vessels and help control blood flow and pressure.
