The Impact of Waterpipe Tobacco Flavors on Waterpipe Smoking Intentions, Perceptions, Patterns, and Toxicant Exposure
Completed · Not applicable
Conditions studied: Smoking, Hookah, Waterpipe Smoking
In brief
The overall aim of the current study is to determine if flavorings contribute to the initiation and maintenance of waterpipe (WP) smoking and also influence how a WP is smoked, which has implications for both risk of dependence but also smokers' level of exposure to tobacco-related toxicants. A total of 94 current WP smokers (47 low dependent, 47 high dependent) will be recruited. Based on our team's previous studies we conservatively assume a 20% attrition rate; thus, we will need to recruit 94 participants to have 76 complete all four sessions. Consistent with other laboratory studies of waterpipe smoking, participants who meet the following eligibility criteria will be asked to take part in the study.
