Both. Take a look at all the possible damage: Summary: (Source: Center for Disease Control and Prevention)
• Cigarette smoking causes more than 480,000 deaths each year in the United States. This is nearly one in five deaths.
• More than 10 times as many U.S. citizens have died prematurely from cigarette smoking than have died in all the wars fought by the United States during its history.
• Smoking causes about 90% (or 9 out of 10) of all lung cancer deaths in men and women.1,2 More women die from lung cancer each year than from breast cancer.
• About 80% (or 8 out of 10) of all deaths from chronic obstructive pulmonary disease (COPD) are caused by smoking.
• Cigarette smoking increases risk for death from all causes in men and women.
• Smoking is estimated to increase the risk—
o For coronary heart disease by 2 to 4 times
o For stroke by 2 to 4 times
o Of men developing lung cancer by 25 times
• Of women developing lung cancer by 25.7 times
• Smoking causes diminished overall health, increased absenteeism from work, and increased health care utilization and cost.
• Smoking causes stroke and coronary heart disease.
• Even people who smoke fewer than five cigarettes a day can have early signs of cardiovascular disease.
• 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.
• Blockages caused by smoking can also reduce blood flow to your legs and skin.
• Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis.
• Cigarette smoking causes most cases of lung cancer.
• If you have asthma, tobacco smoke can trigger an attack or make an attack worse.
• Smokers are 12 to 13 times more likely to die from COPD than nonsmokers.
Smoking can cause cancer almost anywhere in your body:
• Blood (acute myeloid leukemia)
• Colon and rectum (colorectal)
• Kidney and ureter
• Oropharynx (includes parts of the throat, tongue, soft palate, and the tonsils)
• Trachea, bronchus, and lung
• Smoking can make it harder for a woman to become pregnant and can affect her baby's health before and after birth. Smoking increases risks for:
o Preterm (early) delivery
o Stillbirth (death of the baby before birth)
o Low birth weight
o Sudden infant death syndrome (known as SIDS or crib death)
o Ectopic pregnancy
o Orofacial clefts in infants
• Smoking can also affect men's sperm, which can reduce fertility and also increase risks for birth defects and miscarriage.
• Smoking can affect bone health.
o Women past childbearing years who smoke have weaker bones than women who never smoked, and are at greater risk for broken bones.
• Smoking affects the health of your teeth and gums and can cause tooth loss.
• Smoking can increase your risk for cataracts (clouding of the eye’s lens that makes it hard for you to see) and age-related macular degeneration (damage to a small spot near the center of the retina, the part of the eye needed for central vision).
• Smoking is a cause of type 2 diabetes mellitus and can make it harder to control. The risk of developing diabetes is 30–40% higher for active smokers than nonsmokers.
• Smoking causes general adverse effects on the body, including inflammation and decreased immune function.
• Smoking is a cause of rheumatoid arthritis.
