Which messages (contents) promise effective communication with smokers? Which multipliers promise effective communication with smokers? Which settings promise effective communication with smokers? What communication problems arise in motivating smokers to stop smoking? Is it necessary to differentiate between target sub-groups when addressing smokers?
