Cigarette smoke: what's in it?
There are more than 4000 chemicals in tobacco smoke. Many of these chemicals are poisonous and at least 43 of them are carcinogenic (cause cancer).
The 3 major chemicals in tobacco smoke are:
— the chemical on which smokers become dependent;
— which is released when a cigarette burns; and
carbon monoxide (CO)
— a colourless, odourless and very toxic gas. Smokers typically have high levels of CO in the blood.
