The document discusses designing effective warning messages for cigarette packs. It questions whether current warnings adequately inform smokers of health risks and whether the warnings are visible, legible, easily understood, and frightening enough. The document recommends that good warnings be large, preferably covering 50% of the pack, very visible with black on white or white on black text and images, and have a clear, simple message about specific diseases and risks. Possible warning content and rotating multiple messages are discussed, along with using pictures and packaging inserts to provide more information. Group work is suggested to design new warning concepts.
