This would be useful for deposition dose-range studies of different cigarettes types, for example.
After pooling the results obtained with the two research cigarettes types, slopes with statistically significant increases were only seen for the nicotine-based yields of formaldehyde, propionalde-hyde, and styrene (Table 3).
Both high and denicotinized cigarettes improved performance on the spatial processing task, but there was no statistically significant differential drug (Cigarette type) effect.
Remarkably, cigarette conditioning, aging, and cigarette type (depending on the ingredients added to the tobacco during processing, and the tobacco growing conditions) may have a profound effect the size of the particulates emitted during cigarette burning.
Some surveys likewise provide information on cigarette type preference (menthol versus non-menthol) among youth at different stages or trajectories of smoking, based on number of days smoked during the past month and/or cigarettes smoked per day.

Only one cigarette type was smoked during any exposure session (four cigarettes per session).
These shares are used to calculate the numbers of illicit cigarettes, by cigarette type.
Differences by cigarette type were rarely significant for age and time period groupings, due to variations, particularly for COPD, between countries within cigarette type.
i Preference order for cigarette type – handrolled any, both, mainly, only.
