Drinking Age/Smoking Rules
Mexico's nationwide drinking age is 18. Bars here check IDs at the door if they have any doubts about your age. Consumption of alcohol or the possession of an open beverage container is not permitted on public sidewalks, streets, or beaches (outside of licensed establishments), or in motor vehicles, whether moving or stationary.
Smoking is prohibited in all enclosed businesses, including bars and restaurants. Lighting up is allowed at outdoor-seating areas provided by such venues, but not indoors.
