For World Smoke-Free Day we made a very special radio advertisement, in which we used two announcers, one a smoker and the other a non-smoker, to read the same text at the same time. The idea behind this is that the people who heard it can realize first-hand that a smoker has reduced lung capacity, among other conditions that he may suffer from. The mention became a topic of conversation on the country's radio media and the recording of the experience became one of the viral news of the week.
