There is a tendency of waterpipe smokers to advance their practice toward concurrent use (poly-tobacco use) of other tobacco products and nicotine delivery systems. This study investigated poly-tobacco use among waterpipe smokers, and its effect on their quit intention. Descriptive cross-sectional design was utilized to recruit a convenience sample of university students who used waterpipe in three East Mediterranean countries. Using an internet-based survey, data were collected regarding participants' demographics, use of alternative tobacco products and nicotine delivery systems, and waterpipe quitting profile.
