Smoking and Tobacco

Time until Disease



What is the average number of years and rate of smoking it takes until someone will get a disease? What percent of these diseases are fatal?


It`s hard to say how much smoking for how long will lead to disease. The more you smoke and the longer you smoke, the higher your risk of disease is. There is no "safe" amount of smoking. The major diseases linked to smoking are lung cancer, which is fatal in almost every case; chronic lung disease, which kills about half of patients within 5 years; and heart disease,the leading killer in our country, of which about 1/3 are due to smoking. Altogether, smoking kills about 450,000 people in the US every year!
