The mystery of why some people appear to have healthy lungs despite a lifetime of smoking has been explained by UK scientists. The analysis of more than 50,000 people showed favourable mutations in people's DNA enhanced lung function and masked the deadly impact of smoking.
The mystery of why some people are able to smoke heavily without developing a lung condition has been explained by scientists. Mutations in DNA enhance lung function in some people and protect them against the often deadly impact of smoking, according to the Medical Research Council.
Study finds some individuals have genetic variants that allow them to have long-term exposure to a carcinogen without developing lung cancer.
Some people who experience airway constrictions from certain conditions may find that smoking a cigarette may at times actually help them to breathe better. Sometimes they feel that this usage justifies smoking in their cases.
1: Vaping is less harmful than smoking, but it's still not safe. E-cigarettes heat nicotine (extracted from tobacco), flavorings and other chemicals to create an aerosol that you inhale. Regular tobacco cigarettes contain 7,000 chemicals, many of which are toxic.
Cannabis is harmful to the lungs, but in a different way to tobacco, causing significant respiratory symptoms such as bronchitis with evidence to suggest it can result in destructive lung disease – sometimes referred to as 'bong lung' – in heavy cannabis users.
Your lungs are self-cleaning, which means they will gradually heal and regenerate on their own after you quit smoking. However, there are certain lifestyle behaviors you can practice to try and accelerate the rate at which your lungs heal.
Quitting smoking reverses lung cell damage even for decade-long smokers. It's never too late to quit smoking, as a new study shows the lung's ability to heal and regrow damaged cells caused by cigarette smoking, even if they smoked for decades.
Your lungs are a remarkable organ system that, in some instances, have the ability to repair themselves over time. After quitting smoking, your lungs begin to slowly heal and regenerate. The speed at which they heal all depends on how long you smoked and how much damage is present.
Conclusions Smoking only about one cigarette per day carries a risk of developing coronary heart disease and stroke much greater than expected: around half that for people who smoke 20 per day. No safe level of smoking exists for cardiovascular disease.
If you quit smoking, whether you're 40, 50, 60, or 70, there is a great amount of data that says you will live more days and more years from that point forward.

More people are smoking in poorer communities. It is easy to blame people in poverty for making bad choices. But it's more complicated than that. Tobacco companies target these communities to encourage the habit, and the stresses of living in poverty and sometimes hopelessness also cause people to turn to cigarettes.
Within the first month after you quit smoking, your lung function will improve, and this will increase circulation, too. Within nine months, the cilia begin to function normally and symptoms like coughing and shortness of breath become less frequent.
Generally if you haven't smoked for 12 months or more, you're considered a non-smoker.
Lung disease: Vaping can make asthma and other existing lung diseases worse. Breathing in the harmful chemicals from vaping products can cause irreversible (cannot be cured) lung damage, lung disease and, in some cases, death.
1 to 12 months after quitting
Tiny hair-like structures (called cilia) that move mucus out of the lungs start to regain normal function, increasing their ability to handle mucus, clean the lungs, and reduce the risk of infection.
Typically, a smoker's lungs have more inflammation than healthy lungs. The chemicals in cigarettes may damage the tissues in the lungs, which leads to inflammation. Lung inflammation narrows the airways, often causing chest tightness and wheezing.
In outdoor exercising people years long repetition of hyperventilation of subfreezing air causes "eskimo lung" made of obstructive lung disease and increased wall thickness of pulmonary arteries.
Summary. A dangerous condition, ARDS—or wet lung—happens when the lungs are damaged by illness or injury and fill with fluid instead of air. This interferes with airflow in the lungs and oxygen transfer to the rest of the body. Organ failure and, in some cases, death can result.
Clinically, low-malignant nodules can be treated with conservative treatment of regular CT follow-up. If the nodules are increased in size or solid component, more invasive therapy is suggested. Infections, benign nodules, and intrapulmonary lymph nodes often resolve or become stationary after regular follow-up.
