    Abstract:
    BACKGROUND AND AIMS: Concurrent alcohol use and waterpipe (WP) smoking is common among young adults. WP smokers are more than twice as likely to use alcohol as non-users and frequently consume alcohol immediately before and during a WP smoking session. It is unclear what impact alcohol has on WP smoking patterns and resultant exposure to tobacco-related toxicants. The current research aimed to understand the association between alcohol consumption and WP smoke exposure among WP lounge patrons. METHODS: Seventy-one lounge patrons (66.2% male; Mage=27.03, SD=5.32) completed pre- and post-WP session self-report measures and biomarkers of smoking (expired carbon monoxide; eCO) and alcohol consumption (breath alcohol concentration; BrAC) upon entering and exiting the WP lounge. RESULTS: After controlling for number of bowls and charcoals smoked, greater consumption of alcohol was associated with greater smoke exposure among WP lounge patrons (p<0.05), such that a 0.1 unit increase in BrAC was associated with an eCO increase of 19.44ppm. This relationship was mediated by time spent in the WP lounge. CONCLUSIONS: Concurrent alcohol use resulted in greater eCO, likley due to participants spending a greater amount of time in the WP lounge and experiencing longer sustained exposure to secondhand smoke. These findings illustrate a need for further research on the impact of alcohol consumption on WP smoking to assess the potential need for regulation of these products in WP lounges.
