A shopping centre in Shenzhen, China has sparked global conversation after introducing a unique way to enforce its no-smoking policy. The mall has installed toilet cubicle doors made of special frosted glass that turns transparent when cigarette smoke is detected.
The technology works by using sensors to pick up smoke particles. Under normal conditions, the glass remains opaque, ensuring privacy for users. However, if someone lights up inside the stall, the system cuts power to the glass within seconds, making it clear and exposing the smoker to anyone nearby.
This bold move comes as part of a broader effort to curb smoking in public spaces, which remains a challenge despite strict regulations. Smoking in restrooms has long been a problem in many countries, and traditional signage or fines often fail to deter rule breakers.
Reactions online have been mixed. Some applaud the innovation as a clever way to enforce health rules, while others argue it raises privacy concerns. Critics question whether such measures could lead to embarrassment or even safety issues, while supporters say it’s a necessary step to protect non-smokers from second-hand smoke.
The shopping centre has not disclosed whether similar technology will be rolled out in other locations, but the idea has already generated significant buzz on social media. Whether this becomes a trend or remains a one-off experiment, it’s clear that malls are thinking outside the box when it comes to public health compliance.
