Nh. Caskey et al., RAPID SMOKING OF MENTHOL AND NONMENTHOL CIGARETTES BY BLACK-AND-WHITESMOKERS, Pharmacology, biochemistry and behavior, 46(2), 1993, pp. 259-263
White subjects took significantly more puffs of cigarette smoke before
stopping than did black subjects in a modified, controlled-dose rapid
smoking procedure. Paradoxically, however, no racial differences were
detected for changes in carbon monoxide levels, or changes in cardiov
ascular variables (systolic and diastolic blood pressure, and heart ra
te). Due to the cooling and topical anesthetic properties of menthol,
it was hypothesized that menthol and regular cigarette smokers would t
ake more puffs from menthol cigarettes than from regular cigarettes be
fore stopping in the controlled-dose rapid smoking procedure. However,
no difference was observed for the number of puffs taken from regular
as opposed to menthol cigarettes (cigarette type condition) and no di
fferences were found for Cigarette Preference (regular smokers vs. men
thol smokers).
