As of January 15, 2023, by Presidential decree, the law in Mexico became much more restrictive of smoking, tobacco use, vaping, etc. It has been illegal to import (or perhaps even possess) vaping supplies since 2021, but in addition, now it is illegal to smoke indoors or outdoors in restaurants, markets, schools, work centers, event venues, beaches, parks, resorts, all public places, and places in the presence of minors, among many more.  

The link to the law itself is below, and it is attached herewith as a pdf:
