Quantitative comparisons between a nicotine delivery device (Eclipse) and conventional cigarette smoking.

In 1997, R. J. Reynolds introduced Eclipse, a nicotine delivery device (NDD) purported to deliver lower levels of smoke than conventional cigarettes.

Smoking topography: reliability and validity in dependent smokers.

Data from two studies were analyzed to determine whether smoking through the mouthpiece of a topography unit yields consistent measures over time and to verify that smoking through a mouthpiece results in a similar degree of smoke exposure as conventional smoking. In both studies, subjects smoked their usual brand of cigarette ad libitum. In study A, subjects (n=7) smoked through a mouthpiece on 4 separate experimental days.

Clove cigarette smoking: biochemical, physiological, and subjective effects.

Alternative tobacco products such as clove (kreteks) and bidi cigarettes have become increasingly popular among US smokers. The nicotine content of a popular clove cigarette (Djarum Special) filler averaged 7.4 mg; conventional cigarettes contained 13.

Nicotine delivery from smoking bidis and an additive-free cigarette.

The present study was conducted to determine whether smoking bidis, an additive-free cigarette, and conventional cigarettes caused similar biochemical, physiological and subjective effects. This was an open-label, within-subject design. In each session, subjects (n = 10) smoked a single cigarette: an unfiltered Natural American Spirit, an unfiltered Irie bidi, an unfiltered Sher bidi, or one of the participant's own brand.

Bidis--hand-rolled, Indian cigarettes: effects on physiological, biochemical and subjective measures.

Bidis, hand-rolled cigarettes imported from India, have become increasingly popular among US teenagers. These cigarettes are perceived as a safer, more natural alternative to conventional cigarette smoking. The present study was conducted to determine whether the acute effects of bidis and conventional cigarettes are similar.
