Cigarette smoke

Abstract

What is in cigarette smoke? Cigarette smoke is made of gases and very tiny particles that are released when cigarettes are burned. It has over 4,000 compounds including nicotine, tar, arsenic, lead, and carbon monoxide. When you breathe the cigarette smoke into your lungs, the gases and particles get into your blood and organs. Some of these chemicals cross the placenta and lower the amount of oxygen and food available for a developing baby. Second-hand smoke is inhaling the cigarette smoke of another person that is smoking near you.
