Upper aerodigestive tract (UADT) malignancies account for significant proportion of all malignancies. The aim of the study is to know the demography and patterns of tobacco consumption and the proportion of non-tobacco consumers in patients with UADT carcinoma. Patient diagnosed with primary UADT carcinoma visiting outpatient department in a tertiary centre from February 2009 to May 2011 were included in the study. 150 patients were documented with UADT carcinoma and analysed. Among these 133 were males and 17 were female. 40% of them had smoking, 25% had smokeless tobacco, 13% had both smoking and smokeless tobacco and 22% hadn't had any form of tobacco. Carcinoma larynx is the most common site and glottis is the commonest subsite. Most individuals who developed UADT carcinoma have used tobacco in some form. The high proportion of UADT carcinoma in non-tobacco consumer is alarming.
