Smoking leads to increased production of an enzyme that breaks down collagen, so it reduces your skin’s elasticity and makes it look more aged, sagging and wrinkled. Smokers have characteristic patterns of wrinkling of the skin, including lines around the mouth and “crow’s feet” around the eyes.
Overall Health and Life Span

- Smoking is the leading cause of cancer and death from cancer.
- Smoking can cause cancer almost anywhere in the body. Like the lungs, throat, mouth, liver, breasts, colon, pancreas, and stomach.
- Poisons in tobacco smoke can damage or change a cell’s DNA. DNA is the cell’s “instruction manual” that controls a cell’s normal growth and function. When DNA gets damaged, a cell can grow out of control and create a cancerous tumor.
- Smoking increases the risk of coronary heart disease and stroke by two to four times.
- Even people who smoke fewer than five cigarettes a day can have early signs of cardiovascular disease.

- People who smoke are 12 to 13 times more likely to die from chronic obstructive pulmonary disease—which includes emphysema and chronic bronchitis—than people who don’t smoke.
- Ingredients in tobacco can damage your blood vessels and decrease the amount of blood flowing to wounds. They can also decrease oxygen in your blood.
- Smoking can decrease the strength of scar tissue and reduce the chance that skin grafts will be successful.
- Smoking just one cigarette a day can have a negative effect on the body’s ability to heal.
- Smoking can make some conditions more painful. This includes back pain, headaches, rheumatoid arthritis, tooth and gum pain, and fibromyalgia.
- Chemicals in cigarettes may relieve your pain for a bit. But when you’re done smoking, the pain will still be there. When you begin to feel withdrawal from nicotine, your pain can feel even worse.
