Narrative PWLs included a photo showing the lived experiences of individuals affected by alcohol-related cancer (e.g., a headshot of a man with a misshapen jaw) and a text warning statement (e.g., WARNING: Drinking alcohol can cause oral cancer). The warnings focused on oral, esophageal, and laryngeal cancers, respectively.
