[Number of smokers in students (results of a panel-study)]

65% of female and 45% of male enrolers score as non-smokers. This number does not change much in time of study. After studentship this number does not increase also, but the number of cigarettes smoked by the smokers is increasing. As the results of the panel-study (2000 students) show are the habits of smoking/non-smoking very stable. Smokers and non-smokers differ in various traits of personality.
