Unmasking the Appeal

The persistent tactics of the tobacco industry to undermine public health make World No Tobacco Day’s 2025 theme, “Unmasking the appeal”, particularly significant. This theme aligns with the School of Public Health’s legacy of combating tobacco through science, policy and community action. Our work has transformed Hong Kong into a regional leader in tobacco control and continues to set benchmarks for effective interventions.
Since the 1990s, the School’s research has provided the scientific foundation for Hong Kong’s tobacco policies. Professor TH Lam and his team conducted critical studies demonstrating the health impacts of second-hand smoke, which became the scientific basis for the landmark indoor smoking ban in 2007. This policy achievement protects millions from involuntary exposure to tobacco smoke.
The School’s contributions extend beyond policy to practical solutions for smoking cessation. The highly successful “Quit to Win” Contest, conducted in partnership with the Hong Kong Council on Smoking and Health (COSH), represents one of our most impactful community initiatives. It has received overwhelming response from the public, and has successfully integrated scientific research and social marketing to raise public awareness on smoking hazards and smoking cessation.
Our scholars continue to break new ground in tobacco control. A recent study published in Addiction in February 2025 has demonstrated the effectiveness of an innovative chat-based smoking cessation support for employees with mental health symptoms. The randomised controlled trial found participants receiving real-time digital interventions were 37% more likely to quit smoking, with many reporting improved mental well-being. These findings highlight how accessible, personalised support can address the unique challenges faced by vulnerable populations.
As trusted advisors to the HKSAR government, we have shaped numerous tobacco control measures including graphic health warnings, taxation policies, and regulations on emerging nicotine products. Our evidence-based approach to “unmask the appeal” has consistently countered industry strategies while protecting public health interests. The School’s research has been particularly crucial in addressing new threats like e-cigarettes and heated tobacco products.
Looking ahead, the School of Public Health remains committed to achieving a smoke-free Hong Kong. We will continue to develop innovative strategies to reduce tobacco use, particularly among persistent smokers and vulnerable groups. On World No Tobacco Day 2025, we reaffirm our dedication to exposing harmful industry tactics and creating environments where tobacco-free living becomes the norm for all residents.
