Pack size, reported cigarette smoking rates, and public health.

The relation between packs containing 25 or 20 cigarettes each and self-reports of daily cigarette intake was examined in surveys of smoking habits from the United States and Canada. More Canadian than US smokers report smoking 25 cigarettes per day (19.3 per cent vs 2.1 per cent). As market share of packs of 25 increases across six regions in North America, reports of smoking 25 cigarettes per day increase. Even if smoke exposure remains constant, smoking statistics are likely to be influenced by pack size.

Physiological predisposition toward becoming a cigarette smoker: experimental evidence for a sex difference.

In two experiments, nonsmoking females whose urine was acidified were more willing after smoking one cigarette to volunteer to smoke additional cigarettes than were females whose urine was made alkaline. Males did not exhibit this effect. The results indicate that physiological factors that influence nicotine intake during the early smoking experiences of nonsmokers help determine who becomes a cigarette smoker, at least for females. These results may help us interpret recent increases in smoking among teenage females.

A color-matching technique for monitoring tar/nicotine yields to smokers.

We describe a technique that enables individuals to detect the number of puffs taken on a filter cigarette by comparing the "color" of the spent filter to a color scale that simulates the appearance of filters exposed to low-, standard-, or high-yield smoking-machine regimens. Average ratings of filters by 11 subjects correlated almost perfectly with the number of standard puffs to which the filters had been exposed. (Am J Public Health 1982; 72:597-599.)

Have tar and nicotine yields of cigarettes changed?

In official assays of the tar and nicotine yields of 12 popular brands of cigarettes, smoking machines took fewer puffs, on the average, in 1974 than in 1969. The decline in puffs appears to have been a major cause of the reported reductions in tar and nicotine yields during this period.

The misuse of 'less-hazardous' cigarettes and its detection: hole-blocking of ventilated filters.

Smokers of low-yield, ventilated-filter cigarettes sometimes defeat the purpose of the smoke-dilution holes by occluding them with fingers, lips, or tape. Blocking the holes is shown to have large effects on the delivery by these cigarettes of toxic products (nicotine, tar, and carbon monoxide). Techniques for detecting this misuse of "less hazardous" cigarettes are discussed, with particular emphasis on the distinctive signs of hole-blocking which are left in the spent filters.
