Benzo(a)pyrene, a highly carcinogenic chemical found in tobacco smoke, is metabolised in the body to produce toxic chemicals that cause mutations in DNA, leading to cancer.
Benzo(a)pyrene, a highly carcinogenic chemical found in tobacco smoke, is metabolised in the body to produce toxic chemicals that cause mutations in DNA, leading to cancer.

Of the chemicals that are found in cigarette smoke, we know that scores of them are highly toxic and seriously health-damaging. Three major diseases, namely cardiovascular disease (including heart attacks and strokes), emphysema and many cancers (especially lung cancer) are caused in large part by smoking.

Yet, of the thousands of chemicals in cigarette smoke, many have not yet been studied in detail, and their concentrations in cigarette smoke and health effects are not certain.

Emission levels in tobacco smoke are known for only about 500 of the 4000-plus chemicals. About a third of these 500 substances are thought to be safe. As for the other 300+ chemicals, the risks of developing cardiovascular disease, emphysema or cancers by inhaling cigarette smoke are known for only about 100 of them.

There is a list of about 100 of the chemicals in tobacco smoke that have been well investigated insofar as we know their levels in smoke and their risks of causing major tobacco-related diseases. You can find that list here:

It shows the risks of cancer and other diseases from each of these well studied chemicals that are associated with smoking.

Now, please don’t forget that these 100 or-so chemicals are the ones we have good data on. They’re all dangerous, some being highly carcinogenic, some being dangerous to the lungs or the heart, others to the nervous system, the liver, the kidney, and more.

Remember, though, there are thousands of chemicals that we still don’t have data on, and I guarantee you that more dangerous chemicals will be added to this list as more precise data is obtained through research.
