Summary

Characterize effects of relighting on smoke toxicant deliveries and subjective smoking measures. This will be a within-subject comparison in a single experimental group of 30 smokers who report engaging in relighting behaviors. We will assess smoking intensity for relit and non-relit (i.e., smoked continuously without relighting) cigarettes in the natural environment and will conduct in-clinic measurements of smoking topography and subjective responses for relit and non-relit cigarettes. Information on relighting patterns and smoking topography collected from each participant will be used to compare machine-measured smoke yields of key harmful constituents when their usual cigarettes are smoked with and without relighting. Hypothesis: Relit cigarettes will produce higher levels of toxicants than non-relit cigarettes.
