If you smoke 20 cigarettes a day, you can inhale a mugful of tar into your lungs in a year. The HSE notes that within 20 minutes of quitting, a person's heart rate and blood pressure drop, while all the carbon monoxide in their system will be eliminated within 24-48 hours.
Researchers say that people who smoke five cigarettes a day are doing almost as much damage to their lungs as people who smoke 30 cigarettes a day. They say it takes “light” smokers about 1 year to develop as much lung damage as “heavy” smoking does in 9 months.
In most studies, however, the lowest consumption group was set at 1–9 or 1–15 cigarettes per day. One may argue that smokers in these groups clustered close to the upper limit of this consumption span, and that a threshold value might be found on a lower level.
Background: Heavy smokers (those who smoke greater than or equal to 25 or more cigarettes a day) are a subgroup who place themselves and others at risk for harmful health consequences and also are those least likely to achieve cessation.
The amount of life expectancy lost for each pack of cigarettes smoked is 28 minutes, and the years of life expectancy a typical smoker loses is 25 years.

Wheezing: Noisy breathing or wheezing is a sign that something unusual is blocking your lungs' airways or making them too narrow. Coughing up blood: If you are coughing up blood, it may be coming from your lungs or upper respiratory tract. Wherever it's coming from, it signals a health problem.
Can Lungs Go Back to Normal After Quitting Smoking? Yes, your lungs can go back to normal after quitting smoking. One large study found that after 20 years smoke-free, the risk of COPD drops to the same as if you have never smoked and after 30 years, the risk of lung cancer also drops to the same risk as non-smokers.
Your lung functioning begins to improve after just 30 days without smoking. As your lungs heal from the damage, you will likely notice that you experience shortness of breath and cough less often than you did when you smoked.
21 days – Brain biochemistry is returning to normal. 15 days – 90 days – The risk of suffering from a heart attack is starting to decline. Lungs are beginning to recover and your breathing more easily. 20 days – 90 days – Walking is easier and exercising is not a problem it used to be.
After 20 years, the risk of death from smoking-related causes, including both lung disease and cancer, drops to the level of a person who has never smoked in their life. Also, the risk of developing pancreatic cancer has reduced to that of someone who has never smoked.
Smoking reduces oxygen to the skin, which also decreases blood circulation, and that can result in weathered, wrinkled, older-looking skin, explains Dr. Bahman Guyuron, a plastic surgeon in Cleveland, Ohio, and the lead author of the study.
Your lungs have an almost "magical" ability to repair some of the damage caused by smoking - but only if you stop, say scientists. The mutations that lead to lung cancer had been considered to be permanent, and to persist even after quitting.
Yes. So if you need another reason to quit smoking, add premature wrinkles to the list. Smoking can speed up the normal aging process of your skin, contributing to wrinkles and other changes to the appearance of your face.
How smoking affects your weight. Smoking is linked with both weight loss and weight gain. Studies show that long term and heavy smokers are more likely to be overweight or obese than those who don't smoke.
|Time after quitting||Health benefits|
|1 to 12 months||Coughing and shortness of breath decrease|
|1 to 2 years||Risk of heart attack drops sharply|
|3 to 6 years||Added risk of coronary heart disease drops by half|
|5 to 10 years||Added risk of cancers of the mouth, throat, and voice box drops by half Risk of stroke decreases|

How smoking causes hair loss. Smoking tobacco can potentially damage your hair follicles and increase your risk of developing hair loss. A 2020 study compared the prevalence of early-onset androgenetic alopecia in male smokers and nonsmokers between 20 to 35 years old.
Smoking damages the DNA (genetic material) in sperm, which is transferred to the baby. Men produce sperm all the time. Sperm take about three months to mature. This is why quitting at least three months before trying for a baby is important to make sure the sperm is healthy when the baby is conceived.
Yes, you can exercise and smoke, but that doesn't mean you should. Smoking decreases your physical performance and increases your chance of developing several health conditions.
Reduced blood flow and exposure to tar and nicotine can also cause the melanin in your lips and gums to darken, leading to uneven pigmentation. They may appear blotchy, purple, dark brown, or black. The chemicals in cigarettes also have negative effects on the skin.
