In the amounts found in smoke, nicotine does very little harm (apart from causing you to become addicted to tobacco products). Most of the damage to the heart comes from the carbon monoxide and other gases in the smoke. (Carbon Monoxide is the stuff that kills you if you inhale car exhaust.) In concentrated form, nicotine is a deadly poison that is often used as an insecticide by gardeners.
