Tobacco prevention research traditionally focuses upon cigarette smoking, but there is also a need to implement and evaluate the usefulness of waterpipe tobacco smoking (WTS) interventions since it is considered less harmful than cigarettes. This study aimed to assess the impact of an educational intervention on WTS knowledge of health professional students in three academic health institutions in Bahrain.

Conclusions: Our educational intervention with health professional students improved their knowledge about the health effects of WTS. Medical and nursing institutions may consider using various methods such as informative videos and expert lectures to include in their teaching curricula as part of WTS prevention strategies.
