<span style="font-family: Verdana,Geneva,sans-serif;">Bronchitis is a condition in the lungs when the respiratory passages get inflamed and irritated which causes and increase in mucus and harms the lungs. Bronchitis happens when your airways in the lungs become thin and blocked with mucus due to smoking. The symptoms of Bronchitis include continuous coughing, breathlessness for months or years. You may also experience pneumonia and chest infections.



<span style="font-family: Verdana,Geneva,sans-serif;">Emphysema is a little bit different from Bronchitis but still occurs in the lungs. It is when the air sacs are harmed and break down. They the form larger airspaces which means there is less surface area for gas exchange so the amount of oxygen you intake is smaller and you may feel breathless. A symptom of Emphysema is shortness of breath. If you smoke more than 20 cigarettes a day then you are in danger of Emphysema.

<span style="font-family: Verdana,Geneva,sans-serif;">Smokers are much more likely to get cancer because of the chemicals inside of cigarettes like tar, nicotine and Carbon Monoxide. A smoker is also 20 times more likely to have bronchitis than a non smoker is. A smoker is 10 times more likely to get lung cancer than a non smoker because the tumor invades different tissues which causes pain and some other tissues may not be able to function properly.
