In Costa Rica, smoking of any kind (even e-cigarettes) is forbidden in rooms (including room balconies) and public areas, by Government Law #9028.
In March 2012, Costa Rica passed one of the strictest smoking regulations in the world. This legislation has banned smoking in buses, taxis, trains and their terminals, workplaces, public buildings, hotels, restaurants, bars, casinos, and all enclosed public-access buildings, granting no exceptions (no separate "smoking areas" are permitted). Violators will be fined a minimum of 180.000 colons (US$355).
