I am sharing with you about other health related diseases. Smoking is one of them chewing of tobacco is second of them. Smoking at early age is injurious habit most of the people stick through out their life chewing of tobacco is also injurious to health particularly in form of throat cancer. Smoking at early stages is not so apparent but continuous smoking causes infection in the lungs and foodpipe in the human body. Smoking of any form like cigarette, cigar and bidi etc. After eruption of infection in different parts of human body like lose of weight, food pipe & windpipe. Pregant women who smoke endanger their premature babies, by increasing the risk for crossed eyes and retinopathy of prematurity. Several smokers develop an inflammation of the inner layer of the eyes. I hope to expect from other to avoid smoking and chewing of the tobacco.
