Need More Reasons to Stop Smoking?

By Erin Legg

According to the Centers for Disease Control (CDC), lung cancer accounts for about 30% of cancer deaths per year in the United States. The majority of lung cancer cases result from smoking.

Men who smoke are 23% more likely than male nonsmokers to develop lung cancer, and women smokers are 13% more likely than female nonsmokers to develop lung cancer. More than half of lung cancer cases are in former smokers, and 15% are in those who have never smoked.

Smoking also leads to cardiovascular disease, which remains the number one killer in the United States. Diseases associated with smoking include atherosclerosis (hardening of the arteries), heart failure, high blood pressure, and even stroke.

Carbon Monoxide & Nicotine

Cigarettes Broken upSmoking increases the level of carbon monoxide in the blood. Increased carbon monoxide levels in the blood slows transportation of oxygen throughout the body by 5 to 15%. Low levels of oxygen through the body leads to heart disease.

Nicotine is an alkaloid that works upon the brain’s nerve centers that regulate the heart and breathing functions. Causing the small blood vessels to constrict, this lessens the vessels elasticity, increase heart problems, and increases blood vessel disease.

Carcinogens

Constant smoking results in a build up of carcinogens, the cancer producing agents found in tar and tobacco smoke. Carcinogens are deposited in the bronchial tubes that lead to the lungs. From the bronchial tubes, the carcinogens move into the air tubes of the lungs where the cells are attacked and mutated into cancerous cells: lung cancer.
