Bhutan, where smoking is considered bad, banned the sale of tobacco in 2005, but with a thriving tobacco smuggling operation from neighboring India, the ban failed to make much of an impact.

But legislation passed in the new year, granting police powers to enter homes, is set to stub out the habit, threatening five years in jail for shopkeepers selling tobacco and smokers who fail to provide customs receipts for imported cigarettes.

Smoking in private is not illegal in the Himalayan kingdom, but as the sale of cigarettes is banned, smokers are restricted to 200 cigarettes or 150 grams of other tobacco products a month that can be legally imported. And they must provide a customs receipt when challenged by police.
