Cancer,and heart attacks are the long term illnesses that smokers have to deal with. It is difficult to quit smoking because of the nicotine inside the cigarette. Smoking can cause a deadly disease which is lung cancer.
Asthma:
Asthma is a common condition for the lungs. An asthma attack is similar to a heart attack. The direct cause for an asthma attack is swelling and excess mucous in the airways. Inhalers can help people with asthma overcome their attacks because the chemicals in the inhaler make the passage ways to your lungs clear. Living close to a smokestack would be dangerous for people who have asthma. Asthmatics should always carry their inhalers with them because intense stress and anger can cause a asthmatic.
