In this TV ad, pervasive dark smoke curls around guests at a wedding reception revealing the actual amount of smoke emitted by a single cigarette. And the smoker's well-intentioned attempts to blow or waft smoke away from non-smokers does not reduce the potential risk of second-hand smoke to health. The ads make this "invisible killer" visible in this family celebration. The TV commercial is supported by press, online and outdoor advertising from March 5. The ads will run until April 8, coinciding with National No Smoking Day on March 14.
