    The effect of cigarettes yielding less than 10 mg tar was investigated in a representative sample (n = 4729) of 16 and 18 year old Finns. The rate of response was 80%. Cough and phlegm were significantly increased in young people smoking low tar cigarettes. When more than nine cigarettes were smoked daily respiratory symptoms were 2.4-6.2 times more prevalent among those who smoked low tar cigarettes than among those who never smoked. No differences were found between the smokers of low tar and medium tar cigarettes (yielding tar 10-18 mg). These data disagree with the hypothesis that the new low tar brands of cigarettes are less likely to cause respiratory symptoms than the old medium tar brands.
