Imposing smoking ban is a global issue. We should complement Hong Kong having one of the world's lowest smoke prevalence. Joining a crime investigator from Customs and a psychiatrist, I discussed tobacco control in HK from a public administration perspective. The incumbent government forges ahead with a goal to eliminate damages of tobacco. To do so, it takes into account people's health awareness, the capacity of public healthcare system and social moral standard. However, problems such as economic recovery in the post-pandemic era, public order issues resulted by rising illicit trade, the right to choose in a free-market economy, have extended the impacts of tobacco policies to a widened spectrum. A government portrays a role to formulate rules with the premise of balancing interests within different parties and stakeholders. It should make full use of policy instruments such as regulations, public finance, administration and education to build a harmonious society.
