Puffing topography as a determinant of smoke exposure.

摘要: Abstract Puffing topography variables were measured in a well-characterized, male population smoking their own brand of cigarette. Of the puffing variables, interpuff interval appeared to be primary determinant blood concentrations smoke constituents; however, preliminary data homogeneous according nicotine yield cigarette suggest that total puff volume per may also significant levels constituents. Smokers low cigarettes partially compensated for these lower yields by increasing puffed Observed differences associated with increased daily consumption and cumulative history consistent higher exposure Further, although both alcohol coffee are present history, is uniquely However, multiple regression analyses, neither nor histories added significantly prediction constituents over obtained topography.
