Fifty private practitioners and their office staff members were randomly assigned to one of four groups: participants received a protocol for smoking management and a lecture on the consequences and management of smoking, or in addition, had nicotine gum freely available to patients, had stickers attached to their charts, or had gum and reminders. The percentage of patients in each group who had quit smoking a year later was 7.7, 16.3, 8.6, and 16.9, respectively, indicating a significant main effect for the gum conditions. The availability of nicotine gum also significantly increased the amount of time that patients reported they received smoking cessation counseling from the dentists and office staff.
