Myth: if you can't see smoke then there is none

The poster raises awareness that hazardous substances in tobacco smoke remain in a room where someone smoked and may also be released from clothing and body of a smoker. They may persist for hours and cause harm to human health. The poster depicts two people sitting in an office with keyboards. One is a smoker, with a packet of cigarettes and a lighter beside him, and he is emitting a brown-coloured smoke.
