Public support for national comprehensive smoke-free legislation and its setting-specific components: a multijurisdiction cross-sectional survey in China
While prompted support for national comprehensive smoke-free legislation in China is nearly universal, actual support for specific settings varies significantly, with notably lower approval for hospitality and entertainment venues and among current smokers, highlighting the need to distinguish between general and setting-specific backing in future policy assessments.

Imagine a public health goal that sounds simple: keep smoke out of indoor spaces where people gather. This idea is rooted in the understanding that breathing someone else's tobacco smoke, known as secondhand smoke, causes real harm to non-smokers. A third, less visible danger, called thirdhand smoke, lingers on clothes and furniture long after a cigarette is extinguished. For decades, health experts have argued that the only way to fully protect people is to ban smoking entirely in indoor public places, workplaces, and on public transport, without making exceptions for special smoking rooms. While many countries have passed such laws, the question remains: do people actually agree with these strict rules in every single situation? It is one thing to say "yes" to a general idea, but another to say "yes" when it means no smoking in a bar, a hotel, or a cinema.
In late 2022, researchers in China set out to measure exactly how much support exists for this kind of total ban. They conducted a large survey across 48 different cities and regions, asking thousands of adults a series of questions. First, they gave everyone a clear definition of what a comprehensive smoke-free law means: a complete ban on smoking indoors with no special rooms allowed. After reading this, nearly everyone, about 98 percent, said they supported the idea. However, the researchers wanted to know if that support held up when people thought about specific places. They asked the same supporters to rate their feelings about banning smoke in 13 different indoor settings, ranging from schools and hospitals to restaurants and entertainment venues.
The results revealed a clear pattern. Support remained very high for places where children learn or where people seek medical help, such as schools, universities, and hospitals. It was also strong for government buildings and shopping malls. But the numbers dropped noticeably when the question turned to places associated with leisure and socializing. Support for a total ban was lowest in bars, karaoke venues, and cinemas, where only about three-quarters of supporters agreed with the rule. It was also lower in hotels and restaurants compared to other settings. While a large majority of people wanted smoke-free environments overall, a significant portion hesitated when that meant changing the atmosphere in hospitality and entertainment spots.
The study also looked at how knowledge and habits influenced these opinions. People who clearly understood the dangers of secondhand and thirdhand smoke were more likely to support a ban in all 13 settings. Current smokers were less likely to support a complete ban across all venues compared to those who had never smoked. Interestingly, the researchers found that many people who supported a total ban in all 13 indoor locations still agreed to the idea of having a managed "smoking room" in public places. This finding was tricky to interpret because the question did not specify whether the room would be indoors or outdoors. If people imagined an outdoor area, their agreement made sense; if they imagined an indoor room, it suggested a gap between supporting the general law and accepting the strictest version of it.
Ultimately, the research shows that while the public in China is overwhelmingly in favor of smoke-free laws in principle, that support is not uniform across every type of building. The enthusiasm for protecting public health is strongest in places dedicated to work, learning, and care, but it softens in places designed for relaxation and entertainment. The study suggests that to build a truly comprehensive law, policymakers need to understand that winning general approval is different from winning approval for every specific detail. By measuring support for the big picture and the specific parts separately, the researchers provided a more honest and complete map of where the public stands, showing that the path to total protection requires addressing the specific concerns people have about their favorite social spaces.
