Peoplesmokeare at high risk of developing emphysema and bronchitis, two forms of chronic obstructive pulmonary disease. Smoking is associated with 90% of all cases of chronic obstructive pulmonary disease. In addition, smoking also weakens the body's immune system. The risk of respiratory infections such as pneumonia and influenza in smokers is higher than in non-smokers.
Lung cancer
In most countries, tobacco is responsible for more than 90% of deaths fromcancerLung cancer is uncommon in non-smokers. In fact, lung cancer was rare before tobacco use became widespread. Over the past 60 years, the incidence of lung cancer has increased significantly as the number of smokers has increased. On average, smokers have a 5- to 10-fold increased risk of developing lung cancer.
Chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease (COPD) is a disease classification that refers to lung involvement associated with airway obstruction. The two main forms of COPD are chronic bronchitis and emphysema. Smoking is the primary cause of both.
The association between tobacco use and COPD is as strong as the association between smoking and lung cancer. Because smokers have more impaired bronchial mucosal function than nonsmokers, they are more affected by the environment, infections, and toxic fumes. COPD is estimated to be 10 times more common in smokers than in nonsmokers, and tobacco use may be responsible for most deaths from COPD.

Asthma is more severe in smokers. Asthma sufferers who smoke have to deal with increased phlegm, reduced cilia activity, increased susceptibility to infection, increased susceptibility to allergies, and impaired airflow in the small airways. A study of asthma mortality rates among current and former smokers was twice that of non-smokers: 3.7 per 100,000 versus 8.3 per 100,000.
Respiratory tract infection
Smoking weakens the body's immune system. Smokers are more likely to get respiratory infections like pneumonia and influenza than nonsmokers. Smokers not only suffer more from illness, they suffer more from illness. A study of college students who got sick with colds found that smokers had more coughs, phlegm, and wheezing than nonsmokers.
