How dangerous is second-hand smoke?
Second-hand smoke is poisonous and has over 4,000 chemicals in it, including 50 that can cause cancer.
Second-hand smoke can be more dangerous than smoking. Smokers inhale their chemical cocktail through a filter; second-hand smokers arent so lucky.
Second-hand smoke has twice as much nicotine and tar as the smoke smokers inhale, and 5 times more carbon monoxide, a deadly gas that starves your body of oxygen. Other chemicals found in second-hand smoke include:
Benzo[a]pyrene found in coal tar, is a chemical likely to cause cancer in humans.
Formaldehyde used to preserve dead animals.
Hydrogen cyanide used in rat poison.
Ammonia used to clean floors and toilets.
Each year in Canada, second-hand smoke causes more than 1,000 deaths among non-smokers, mainly from lung cancer and heart disease, and keeps many more from leading healthy lives.
