3. Benzene

Benzene is a colorless, flammable liquid found in cigarette smoke, and is considered a Group 1 carcinogen. About half the exposure to this toxic chemical in the United States comes from cigarette smoke. Those consistently exposed to benzene, such as factory workers and chain smokers, face an array of symptoms such as dizziness, rapid heart rate, and headaches. It has also been shown to cause blood disorders and blood cancer, according to the American Cancer Society and the National Cancer Institute. A high intake of benzene may result in death.
