Of all the chemicals in tobacco smoke, it does the most damage to the heart and blood vessels. Hydrogen cyanide does not cause cancer, but it increases the risk of other chemicals causing cancer by damaging cilia. These are tiny hairs lining the airways that help to clear toxins away. By killing cilia, hydrogen cyanide causes other dangerous chemicals to be stuck in the lungs and airways. Hydrogen cyanide=シアン化水素（＝青酸ガス）
Ammonia is a gas with a strong, irritating smell, and is used in some toilet cleaners. Some studies have found that ammonia enhances the addictive power of nicotine. It changes nicotine into a gas that is more readily absorbed into the lungs, airways and bloodstream.
Like carbon monoxide and hydrogen cyanide, ammonia also kills cilia.
