Smoking increases the mortality rates for a variety of diseases, including lung cancer, heart disease, emphysema, bronchitis, and chronic airways obstruction. Simply stated, there is no safe way to smoke. Although low-tar and low-nicotine cigarettes may reduce the risk for lung cancer somewhat, they do not lessen the risk for cardiovascular heart disease (CHD). In fact, smoking accelerates atherosclerosis – the depositing of plaques containing cholesterol and lipids on the inner walls of arteries. It also increases the risk for stroke.
The risk for CHD increases along with the number of cigarettes smoked daily. Quitting smoking sharply lowers the risk, even in the first year and no matter what a person's age. Quitting also reduces the risk for a second heart attack in those who have already experienced one.
No matter how long you've smoked, quitting has immediate benefits. Within minutes after you smoke that last cigarette, your body begins a series of changes that continue for years.
