Lungs are essential respiratory organs for purifying the blood by rejuvenating it with oxygen.Now what happens when you smoke on and on and on endlessly for years?They will get choked with the tar like substance caused due to intake of smoke.The condition will be similar to that of a choked air/oil filter in the car's engine.The choked lungs will perform partially and thus it will lead to improper functioning of the human body.you might not feel the pinch in the initial years,but by the time you realize it it would have hammered your respiratory and other body systems badly.
