The effects of tobacco smoke on the respiratory system include: irritation of the trachea (windpipe) and larynx (voice box) reduced lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages.
Smoking causes fatal diseases to develop in many parts of the body including cancers of the upper and lower respiratory tracts (mouth, nasopharynx, larynx, and lung), the oesophagus, and the kidney.
