Tar yields of cigarettes and male lung cancer risk.
Of 252 male lung cancer patients, 248 or 98% were cigarette smokers, significantly (P less than .001) more than in the control group (526 = 64% of 839). In relation to the relative risks (RR) of never-smokers, the adjusted (for age, total years smoked, and average number of cigarettes smoked per day) lung cancer RR for smokers who had exclusively smoked cigarettes belonging to group II (15-24 m...
متن کاملTar, nicotine, and carbon monoxide yields of some Nigerian cigarettes.
Fourteen cigarette brands manufactured in Nigeria in 1981 were analysed to determine the tar, nicotine, and carbon monoxide yields. Five of the brands belonged to the high and middle to high tar category (greater than 22 mg/cigarette) and nine to the middle tar (17-22 mg/cigarette) category. None of the cigarettes was in the low to middle and low tar (less than 17 mg/cigarette) category. The ni...
متن کاملTrends in sales weighted tar, nicotine, and carbon monoxide yields of UK cigarettes.
BACKGROUND Reducing tar yields of manufactured cigarettes has been an important plank of government policy on tobacco, but sale weighted yields are not routinely published. METHODS Tar, nicotine, and carbon monoxide yields measured by the Laboratory of the Government Chemist were combined with cigarette brand market shares from national surveys of smoking behaviour to generate sales weighted ...
متن کاملRelative intakes of tar, nicotine, and carbon monoxide from cigarettes of different yields.
The relative intakes of tar, nicotine, and carbon monoxide were estimated in 2455 cigarette smokers, who freely smoked their usual brands of cigarette. The estimates were derived by using an objective index of inhaling based on the measurement of carboxyhaemoglobin divided by the carbon monoxide yield of the cigarettes smoked, after background and carry over carboxyhaemoglobin effects had been ...
متن کاملDetermination of tar, nicotine, and carbon monoxide yields in the mainstream smoke of selected international cigarettes.
OBJECTIVE Survey of nicotine, tar, and carbon monoxide (CO) smoke deliveries from 77 cigarette brands purchased in 35 countries was conducted using a standardised machine smoking method. The goal of this study was to determine regional variations and differences in the tar, nicotine, and CO smoke yields of a cigarette brand manufactured by a leading transnational corporation and of non-US local...
