A total of 510 questionnaires was distributed to all the undergraduate students of Topiwala National Medical College to collect data on the practice of tobacco smoking and its relation with respiratory tract infection. The questionnaires were filled on the spot under supervision. The total percentage of smokers is estimated as 21.0%. It is found that respiratory infections are more common among smokers and there is a strong association between history of adenoidectomy or tonsillectomy in students to parental smoking habits.
