This document discusses social smoking among young adults aged 18-25. It defines social smoking as non-daily smoking driven by social influences. Three-quarters of social smokers are at high risk of becoming regular smokers, and over half of regular smokers started as social smokers. Previous public health campaigns have aimed to educate social smokers that they are still smokers and at risk of addiction. This document proposes a new public health campaign using television, posters, bar coasters, social media and cigarette package warnings to educate young adult social smokers about the health risks and addiction risks of social smoking.
