Most respondents had good knowledge about shisha (59.2%). Poor knowledge about shisha (adjusted odds ratio [aOR] 2.37, 95% CI 1.57-3.59)], living in a hostel (aOR 2.00, 95% CI 1.29-3.11), friends' use of shisha (aOR 5.41, 95% CI 3.03-10.43) and alcohol consumption (aOR 1.91, 95% CI 1.24-2.94) were associated with shisha smoking. The prevalence of shisha smoking among university students in Buea is high; about one-quarter of the students have poor knowledge about its harmful health effects.
