Smoking room is often supported by tobacco company to reduce socio-political pressure from indoor smokefree policy. In Korea, smoke free policy is not comprehensive because smoking is still allowed in several indoor spaces. In addition, smoking room is allowed by law for some facilities. According to guideline of smoking room, secondhand smoke must not be infiltrated to non-smoking area by complete sealing and/or separate ventilation. However, smoking room is usually not completely sealed. Many previous studies of PM2.5 measurement demonstrated that secondhand smoke in smoking room was infiltrated to adjacent nonsmoking area. Smoking area can have extremely high PM2.5 concentration. Even when smoking room was highly ventilated, PM2.5 in smoking room was up to 325 ㎍/㎥. Although PM2.5 concentrations in nonsmoking area were slightly decreased with various separation types, the levels were significantly higher than the US ambient air quality standard of 35 ㎍/㎥. Various monitoring demonstrated that complete sealing required by law was not achieved in smoking area. Effectiveness of smoke free policy was reduced by presence of smoking room. Various evidences determined ineffectiveness of smoking room. Therefore, smoking room should not be allowed with comprehensive indoor smoke free policy.
