mokers are at greater risk for diseases that affect the heart and blood vessels (cardiovascular disease).1,2
Smoking causes stroke and coronary heart disease, which are among the leading causes of death in the United States.1,3
Even people who smoke fewer than five cigarettes a day can have early signs of cardiovascular disease.1
Smoking damages blood vessels and can make them thicken and grow narrower. This makes your heart beat faster and your blood pressure go up. Clots can also form.1,2
A stroke occurs when:
A clot blocks the blood flow to part of your brain;
A blood vessel in or around your brain bursts.1,2
Blockages caused by smoking can also reduce blood flow to your legs and skin.1,2
Smoking and Respiratory Disease
Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs.1,2
Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis.1,2
Cigarette smoking causes most cases of lung cancer.1,2
If you have asthma, tobacco smoke can trigger an attack or make an attack worse.1,2
Smokers are 12 to 13 times more likely to die from COPD than nonsmokers.1
