Smoking greatly increases the risk of major cardiovascular diseases. Heart disease is the number one cause of death in America, and reduced smoking or no smoking lowers the risk of disability and death from cardiovascular diseases.

Low levels of cholesterol and blood pressure also help reduce CVD. Hundreds of scientific studies have shown that smoking is a cause of heart disease. Smokers double their risk of dying from heart disease compared to non-smokers.

If smokers have either high blood pressure of high cholesterol their risk increases. If smokers have all three conditions, their risk jumps even higher. The risk also increases by starting to smoke at an early age, the number of cigarettes smoked each day, and how deeply smokers inhale.

Researchers calculate that smoking causes 30% of chronic heart disease deaths and 21% of other cardiovascular diseases in America. If smokers survive a heart attack but continue to smoke, they are more likely than nonsmokers to have another heart attack. Pipe and cigar smokers have a slightly lower risk of developing heart diseases compared to cigarette smokers, but they still have a much greater risk than nonsmokers.

Pipe and cigar smokers generally do not inhale as much or as deeply compared to cigarette smokers, so they inhale less tar and nicotine. However, people who switch from cigarettes to cigars or pipes have a much greater tendency to inhale.

Nicotine, carbon monoxide, and possibly other chemicals inhaled from smoking can cause arteriosclerosis, or narrowing of the arteries. These chemicals encourage fatty materials such as cholesterol to cling to artery walls. Over time, artery walls thicken and harden. Blood flow slows, or less oxygen travels to body tissues. This can lead to shortness of breath or even death from heart attacks or strokes.

Smoking also changes blood platelets. Blood platelets cause blood to clot. In smokers, platelets clot too fast and die too soon, Which results in thickening of the blood. This can also lead to a heart attack.

Oral and Dental health
Smokers may not notice, but others are often aware that smokers generally have bad breath and stained teeth. Tooth stains are especially severe in cigar smokers and tobacco chewers. Pipe smokers can develop uneven teeth from clenching the pipe stem, and their teeth tend to break more often. Gum diseases appear more often in smokers and in stuff users.This can lead to loose teeth, bleeding and tooth loss.
