The effects of tobacco smoke are just as bad, if not worse, in nonsmokers as in smokers. All of the risks for smokers also hold true for exposure to second hand smoke. Tobacco smoke is made up of many hazardous vapors and particles that when inhaled are harmful to both the smoker and to others around. The smoke at the end of a burning cigarette has more particles that are smaller and more harmful than the smoke directly inhaled by the smoker. These smaller particles go deeper into the lung tissue and do more damage. With reduced oxygen, the heart, lungs and brain cannot function properly. This leads to permanent brain and blood vessel change.
