Abstract: Tobacco smoking is one of the biggest public health threats to the world, not only harmful for the smokers but also for the second-hand smokers. This study aims to assess the awareness on passive smoking among smokers’ villagers in Sg Pelek, Sepang, Selangor. A cross sectional study was done by using simple random sampling. Respondents that fulfill the inclusion & exclusion criteria were interviewed with validated questionnaires and data were analyze using SPSS. The prevalence of smoking was 13.9%. The awareness on passive smoking among smokers was 42.4% and 57.1% of them still smoke in front of others despite of having the awareness. In order to make the public places in Malaysia as smoke free zones, an integrated effort needs to be initiated by various authorities. The perception of secondhand smoke health effects among Malaysians should also be instilled.
