The new Tourism Law prohibits smoking inside all hotels in Macao. All guests in all hotels and commercialised resorts will need to wear nicotine-dispensing masks, undergo heat checks and give a special Macao Health Code upon request. All resorts and hotels have strict prohibitions against smoking, as it is considered a dangerous "recreational addiction". The move, aimed at curbing the island's increasing rate of smoking, has caused several airlines to stop air travel to Macau. Other international carriers, however, have not given up on their flights to the small region.
