It is interesting to note though that nearly twice as many "light smokers" (less than 10 cigarettes per day) as "heavy smokers" (25 cigarettes and over) claim to do this "often".
Opmerkelijk is dat bijna twee keer zoveel "lichte rokers" (minder dan 10 sigaretten per dag) als "zware rokers" (25 sigaretten per dag of meer) beweren zich "vaak" zo te gedragen.
