Secondhand smoke poses serious harm even to non-smokers. Secondhand or passive smoking refers to the involuntary smoking or inhalation of tobacco smoke. Smoke from this process usually contains a mixture of smoke given off by a tobacco product coupled with the smoke exhaled from the lungs of smokers. Tobacco smoke may stay in the air for hours after cigarettes have been consumed and it can be involuntarily inhaled by non-smokers. Secondhand smoke may seem harmless, but it can actually contain many toxic chemicals that are carcinogenic or and other substances that can cause cancer.
