Warning! You Can Get Heavy Metal Toxicity From Smoking

Most people realize that smoking causes lung cancer and increases the risk of heart attack, stroke, and other lung diseases. What fewer people realize is that smoking tobacco also increases exposure to poisonous metals – particularly cadmium. People who smoke are at risk of developing high blood cadmium levels and of suffering the harmful health effects of this toxic metal. Other than occupational exposure, tobacco is one of the most important sources of cadmium exposure – and one that can be prevented.  

Cadmium Sources: What is Cadmium and Where is It Found?

Cadmium is a heavy metal that’s released as a by-product of certain industrial operations such as metal processing and mining. It can also be found in water and in foods that are grown in areas near industrial sites where the soil contains high amounts of cadmium. Cadmium is also released when fuels are burned – so one source of exposure is breathing in car exhaust fumes on a regular basis.

Cadmium is a particular concern for smokers since cigarettes are a source of cadmium. According to information published on Wikipedia, about ten percent of the cadmium found in a cigarette is absorbed when a smoker smokes and this toxic metal can’t be eliminated from the body. There is no good chelating agent available to remove cadmium in those who take in too much.

The Dangers of Heavy Metal Toxicity: Why Cadmium is a Problem

Cadmium is a known cancer-causing agent. Not only that, but high blood cadmium levels can cause kidney disease, lung problems, and anemia. It also weakens the immune system. Even more concerning is the fact that cadmium can’t be eliminated from the body and gradually builds up over time. The key is to reduce exposure to it by not smoking tobacco and by not eating contaminated foods or getting occupational exposure. Certain foods such as shellfish and organ meats are known to contain higher levels of cadmium. Vegetables, grains, and potatoes grown in cadmium polluted soil can also be a source of cadmium exposure.

Why Does Smoking Pose a Risk of Heavy Metal Poisoning?

Smoking raises blood cadmium levels. In fact, tobacco smokers have up to five times higher blood cadmium levels compared to non-smokers. Not only does cadmium increase the risk of kidney disease and anemia, recent studies show that it also elevates the risk of heart and peripheral vascular disease and may be the one of the primary causes of emphysema in smokers.

The Bottom Line?

Tobacco smoking is one of the most common ways people are exposed to cadmium and once it enters the body, it can’t be eliminated. If you’re a smoker, have your blood calcium level checked and take the steps needed to quit smoking to reduce your exposure to cadmium.
