While cigarette puffing style, measured by smoking topography, is highly variable between individuals, smoking behavior or style tends to vary relatively little within individuals. Recent research has demonstrated that certain situational factors may produce variation in smoking topography, including location of smoking. Smoking topography directly observed by researchers in a laboratory may differ from that indirectly observed via portable measurement devices at participants' homes. The introduction of clean indoor air laws may also influence smokers' puffing styles, as smokers modify their smoking topography to ensure a quicker, more efficient smoking style. The goal of this analysis was to examine whether directly observed laboratory measures are representative of indirectly observed smoking behavior and to examine the influence of smokers' preference for indoor or outdoor home smoking on puffing style. Overall, participants smoked more intensively in the directly observed setting than when in the indirectly observed setting in terms of total volume intake, inter-puff interval, and total time spent smoking. This difference was most pronounced among individuals who reported smoking indoors when at home. The data suggest that adherence to an indoor home smoking policy may further influence an individual's smoking behavior.
