Reports from Saudi Arabia have showed a relationship between patients with oral cancer and a history of smokeless tobacco usage. Thus the aim of this study was to assess the levels of awareness of smokeless tobacco users towards the health effects of smokeless tobacco usage and find out, which are common smokeless products used in Northern and Western Saudi Arabia. This is a descriptive cross sectional study conducted in Northern and Western Saudi Arabia. The study included 420 smokeless tobacco users’ volunteers living in three cities: Tabuk and Hail cities in Northern Saudi Arabia and Makkah in the Western Saudi Arabia. Out of 420 respondents, only 198 (47.2%) heard something about the health consequences of smokeless tobacco use and the remaining 222(52.8%) were completely ignored the health effects resulting from smokeless tobacco use. With regard to the smokeless tobacco type, the most common was Toombak followed by Shamma, Afdhal and Nashoog representing 127(3.2%), 65(15.5%), 64(15.2%), 44(10.4%) and 33(7.8%) in this order. Different forms of smokeless tobacco are prevalent in Saudi Arabia. Since most of the users were non-Saudi workers, work places may serve as an effective platform to deliver targeted strategies aimed at smokeless tobacco cessation.
