I was just on a business trip with a colleague of mine who had just returned from another trip to Chile. This guy is a smoker, and he was so proud to show off his packs of Marlboro's he bought so cheaply there - and each one had a graphic picture of a person who had oral cancer and a huge warning from the health ministry. He laughed about it... and kept on smoking. He even bragged about the 2 extra cartons he smuggled back in his suitcase - one for his wife...
Here's a link to show what Chile has done on cigarette packaging
