There is strong evidence that suggests that people who smoke cigarettes on a regular basis for a long period of time are at an extremely high risk of developing larynx and lung cancer. Researchers are still trying to figure out exactly how it is that smoking causes these types of cancer, as it is not yet understood clearly.

Normal cells that experience damage are able to repair themselves on their own. Sometimes cells are completely removed and then are replaced by the body’s lymph system. This process can start to go wrong, however.

Sometimes new cells begin to grow into odd, unnatural shapes and as a result do not carry out their normal tasks properly. When this unnatural growth becomes a big enough problem that the body cannot handle it, it has officially become cancer.

Many of the substances that are found in cigarette smoke have been proven to be carcinogenic.

When the paper in a cigarette burns, it releases tar. Each cigarette tends to contain between 10 and 14 milligrams of tar. This tar collects in the tiny air filled sacs of the lungs, called alveoli, where oxygen is usually transferred into the blood. The presence of tar in the alveoli irritates the cells and eventually leads to their unnatural growth.

Other compounds, called nitrosamines, are present in varying amounts. They’re known to be carcinogenic from hundreds of clinical studies on small mammals. NNK is present in a very low concentration: 56.53 nanograms per cigarette. Other nitrosamines, like NNN and NAT, are present in roughly similar amounts.

A few dozen nanograms (one billionth of a gram – 1 g = 0.0353 oz) may sound like a small amount. But sometimes small amounts can have a large effect. Dog’s noses, for example, are so sensitive they can detect a few molecules of certain substances. Some systems in humans are equally sensitive to certain chemicals. Add to that the fact that many of the compounds and their effects are cumulative and the case begins to look very strong.

No study has found any link between cancer and consuming one or two cigarettes per day. But such smokers are extremely rare and the odds of them catching some other serious disease are so much higher it may be masked. A smoker who consumes a pack a day for 20 years has 2-4 times the chances of getting lung cancer than a non-smoker.

Heart disease is very serious and over and over we hear how smoking can cause it. But how? How can smoking lead to heart disease? In fact, what exactly is heart disease?

Heart disease is when one of your major arteries that lead from your heart and carry needed oxygen to the blood becomes partially blocked. If the blockage worsens it can lead to a heart attack or a coronary meaning your coronary artery is blocked and the flow in that artery stops. That is why another term for heart disease is coronary artery disease.

Smoking makes a person’s chances of having coronary artery disease or heart disease much greater for a variety of reasons.

Carbon monoxide is present in cigarette smoke. It binds with hemoglobin, the molecule in red blood cells that helps transport oxygen throughout the body, including the heart. Reducing the oxygen to the heart ups the odds of heart disease.

Cigarettes also contain nicotine which works against the heart because it robs the blood of oxygen that the heart needs. It also makes the blood clot easier which increases your risk of a heart attack.

But even more subtle, yet still dangerous, effects are produced by nicotine. One of the most serious, long term, is that it encourages the growth of fatty deposits on the arteries, constricting blood flow and hardening the blood vessel.

Arthrosclerosis is a condition where good cholesterol called HDL (high density lipoprotein) is decreased in the blood which allows for fat deposits to form on the arteries. Smoking greatly encourages and feeds this condition.

Reducing the diameter of the artery increases blood pressure. That makes it more likely that any weakness present in the artery wall, something termed an aneurysm, will lead to a rupture. That leads to oxygen starvation to the brain, resulting in a stroke. That’s why one so often sees ‘raises the risk of heart disease and stroke’ discussed in the same sentence.

When your arteries become hard they are not able to perform their tasks without extreme stress.

Blood will not flow properly through arteries if there are holes in your arteries. Also, if your blood does not continue to flow freely through your arteries the results are always damaging but can be deadly. Every living tissue in your body is depending on the blood it needs survive and that blood is delivered through the arteries of your heart.
