Vietnam is among the countries with the highest smoking prevalence among male adults, as well as high prevalence of secondhand smoke exposure at indoor places. In many countries, including Vietnam, exposure to tobacco smoking is greatest in restaurants/bars and hotels. This study aims to analyze the compliance of hotels and restaurants to smoke-free environment regulations before and after an intervention.Methods:   Direct observations were done at the receptions, conference rooms, designated smoking areas, restaurants, and lobbies of 140 hotels and the dining rooms, kitchens, and toilets of 160 restaurants before and after an intervention. The intervention was a training course conducted by police officers followed by 3 monthly supervision visits by police officers. Compliance with smoke-free enviornment regulations was observed and assessed to generate a compliance score for each location and overall. Tobit regression was used to examine the relationship between compliance scores and the intervention and other variables such as hotel and restaurant characteristics.Results:   Before the intervention, the highest compliance rates were found for “no tobacco advertisement” and “no cigarette selling” regulations (95%-100%) in almost all sites in hotels and restaurants. The lowest compliance rates were found for “having nonsmoking signs.” The rate of compliance with all regulations was only 5% for hotels and 0.06% of restaurants. Improvement after intervention was clearly observed, in the rate of compliance with all regulations by more hotels (15.7%) and overall compliance scores of hotels and restaurants.Conclusions:   The intervention with participation of the police officers proved to be effective in improving compliance with smoke-free regulations. It is recommended to continue this intervention in the same areas as well as to expand the intervention to other areas.
