Yes. In simple form, smokers have worn their lungs out so it's harder to keep a higher lung capacity.
Lung cancer is less common in nonsmokers compared to smokers. However, nonsmokers can still develop lung cancer due to other factors such as exposure to secondhand smoke, radon gas, air pollution, or genetic predisposition.
Lung cancer, tar, emphysema, for smokers and nonsmokers
Smoking adversely affects the lungs of both smokers and nonsmokers exposed to secondhand smoke. For smokers, it leads to chronic respiratory issues, reduced lung function, and increased risk of lung diseases such as COPD and lung cancer. Children of smoking parents, even if they do not smoke themselves, are at a higher risk for respiratory problems, asthma, and developmental issues due to exposure to secondhand smoke. This environment can significantly hinder their lung health and overall well-being.
In easy terms, your lungs get full of tar and junk, so when you breathe in not as much oxygen is able to get through the little capillaries in your lungs and into your blood stream. Think of your lungs as being like a clogged sink.
Smokers typically have a reduced vital capacity compared to non-smokers due to the harmful effects of tobacco smoke on lung function. Smoking leads to inflammation, airway obstruction, and damage to lung tissues, which can diminish the lungs' ability to expand fully. As a result, smokers may experience decreased lung volume and overall respiratory efficiency. This reduction in vital capacity can contribute to chronic respiratory issues and decreased physical performance over time.
The answer is, it isn't. A recent study comparing nonsmokers, tobacco-only smokers and marijuana-only smokers found there is no correlation between lung cancer and marijuana use, even in heavy marijuana smokers. A link to the study is given below: (See related links) You still have an increased risk of lung disease and "smoker's cough", but consider this myth debunked.
On average, smokers die about 10 years earlier than nonsmokers. This difference in life expectancy is due to the numerous health risks associated with smoking, including lung cancer, heart disease, and respiratory illnesses. The exact number of years can vary based on factors such as the quantity smoked and individual health conditions.
Lung cancer is significantly more common among smokers compared to non-smokers. Smokers are about 15 to 30 times more likely to develop lung cancer than non-smokers.

no, damage to lungs is an environmental factor and there for cannot be passed on
Asbestos is a direct cause of lung cancer. This relationship was first determined in 1925. Nonsmokers exposed to asbestos are five times more likely to develop lung cancer than other nonsmokers.
