Cancer-causing chemicals in tobacco smoke

Cigarette smoke is a mixture of materials over 4,000 chemicals, many of which are harmful to
the human body. All currently available tobacco products that are smoked will deliver substantial
amounts of toxic chemicals to their users and those who breathe their smoke. Cigarette smoke
is a combination of:
1) mainstream smoke - the smoke inhaled by a smoker;
2) sidestream smoke - the smoke from the end of a lit cigarette; and
3) secondhand smoke - the smoke exhaled by a smoker plus sidestream smoke.

Of the more than 4,000 chemicals present in cigarette smoke, more than 60 have been identified
as cancer-causing chemicals, 11 of which are known to cause cancer in humans and eight that
probably cause cancer in humans.

Cancer-producing chemicals in tobacco smoke include: Benzene; 2-naphthylamine; 4-aminobiphenyl;
Chromium; Cadmium; Vinyl chloride; Ethylene oxide; Arsenic; Beryllium; Nickel and Polonium-210.
