Data regarding demographic variables, smoking patterns, and knowledgeabout shisha smoking were collected in local languages. Logistic regression was performed to assess risk factors.
Results: Of 239 participants, 61.9 % were male and 99.2% revealed their smoking status. Some 57.4% weresmokers: 50.7% only cigarettes, 5.9% only shisha and 42% both.

In a univariate model, male gender, age 33-52 yearsand monthly income > MYR 4,000 increased the risk and unemployment and being a student decreased therisk. In a multivariate model, male gender increased the risk of smoking, while being a student decreased therisk, adjusting for age and income. The perception of shisha being less harmful than cigarettes was present in14.6% and 7.5% had the opinion that shisha is not harmful at all, while 21.7% said that it is less addictive thancigarettes, 39.7% said that shisha did not contain tar and nicotine, 34.3% said that it did not contain carbonmonoxide and 24.3% thought that shisha did not cause health problems.
