Those hoping to light up a cigarette in Mexico will now be limited mostly to their homes and other private residences after a strict smoking ban went into effect this week.

Mexico has enacted a law that bans smoking entirely in all public places, including parks, beaches and hotels. Initially approved in December 2021, it's an expansion of a 2008 law that prohibited smoking in public indoor spaces, like bars and restaurants.

The new reform also bans tobacco advertising and sponsorship and the display of cigarettes in shops. It puts some new limits on e-cigarettes and vaping, as well.

The reform has drawn pushback from some smokers and has raised concerns about enforcement. But the World Health and the Pan American Health organizations praised the move, with PAHO noting that 10% of deaths in Mexico each year are attributable to tobacco use and exposure to tobacco smoke.

Mexico’s law is currently among the most robust smoking prohibitions in the world.
