The non-smoking in public places law was passed last November. Clean Air, the organisation that fights passive smoking, asked us to create a campaign raising awareness of the change in the law and its results. We decided to show the change from an interesting amusing angle, not a didactic one. A fascinating insight that we learnt while working on the project was that since the new law was passed, something had changed in places like cafes and restaurants: having a conversation with a smoker would never be the same as before.
