BEIJING – With hand signals and snitches, officials in Beijing, China, hope to enforce the city’s newest smoking ban, which begins in June. The ban forbids smoking inside public places and outside certain buildings, such as hospitals and school grounds, Vice News reports.

Having seen little success with previous efforts to curb smoking, China is turning to its citizens to help enforce the ban. Citizens will be tasked with snapping photos or videos of smokers and uploading them to a WeChat public account (the Chinese version of WhatsApp). Armed with photographic evidence, officials will rush to the scene to levy fines on smokers who have enjoyed a puff or the businesses who allowed it.

Beijing also wants its citizens to use a new hand signal to indicate that a smoker must “stub that thing out now!” The city faces a monumental task in making the ban effective, given that a quarter of all Chinese smoke. If Beijing can make the ban work, it will likely be rolled out to the rest of the country.

Other attempts to reduce smoking failed spectacularly, with a 2011 ban ignored by the populace and another ban only surviving through the hosting of the 2008 Olympics. Wu Yiqun, deputy chief of the China Tobacco Control Resource Center, thinks that this time will be successful. “It has been laid out clearly that venue owners need to be responsible,” he said. “That is a big incentive to comply, rather than just having a few people walking around on the street supervising and writing tickets.”
