Lung cancer
In most countries,cigaretteis responsible for more than 90% of lung cancer deaths. In factcancerLung cancer was a rare disease before tobacco use became widespread. Over the past 60 years, the incidence of lung cancer has increased dramatically along with the increase in the number of smokers.

The average smoker increases their risk of developing lung cancer by 5 to 10 times. Several studies have identified three important trends: cancer risk increases with the number of cigarettes smoked/day; cancer risk increases with the duration of smoking, measured in years; and cancer risk increases with young people who start smoking.
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 similar to the association between smoking and lung cancer, because smokers often have impaired bronchial mucosal function than nonsmokers, and they are more affected by the environment, infections, and toxic fumes.
Chronic obstructive pulmonary disease is estimated to be 10 times more common in smokers than in nonsmokers, and tobacco use may be involved in most deaths from chronic obstructive pulmonary disease.

In smokers, asthma will be worse. Asthmatics who smoke will have to endure a lot of phlegm, reduced cilia activity, are susceptible to infection, are susceptible to allergies and affect air circulation in the small airways.
One study found that the death rate from asthma among current or former smokers was double that of non-smokers.
Respiratory tract infection
Smoking weakens the body's immune system. Smokers are more likely to develop respiratory infections such as pneumonia and influenza than non-smokers.
Smokers not only suffer more from illness, they suffer more from illness. Studies show that smokers suffer more from cough, phlegm, and wheezing than non-smokers.
