What this trial studies

Researchers will run a randomized experiment with about 1,185 adults who currently smoke menthol cigarettes and are at least 21 years old. Participants are randomized to one of three groups (menthol ban plus quit campaign, menthol ban alone, or control) and complete two in-person shopping visits about one week apart at an experimental UNC Mini Mart stocked with tobacco and everyday items. Between visits, participants receive text-message ads matched to their assigned group, and investigators record in-store purchases and collect computer-based survey data. The primary outcomes are changes in tobacco purchasing behavior and related self-reported measures.

Who should consider this trial

Good fit: Ideal candidates are English-speaking adults (21+) who currently smoke menthol cigarettes, have purchased menthol cigarettes in a store in the past month, can attend two in-person shopping visits, can complete computer surveys, and can receive images by text message.

Not a fit: People who do not smoke menthol cigarettes, are under 21, are pregnant or breastfeeding, or are already enrolled in another quit-smoking study are not eligible and unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, pairing a menthol ban with supportive quit-smoking messages could reduce purchases of menthol cigarettes and help more smokers quit.

How similar studies have performed: Prior policy analyses and advertising interventions suggest menthol restrictions and quit campaigns can reduce smoking, but combining them in a randomized simulated-store experiment is relatively novel.
