Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will investigate the effects of narratives on demand for low and high ventilated cigarettes and substitution for alternative products in the Experimental Tobacco Marketplace.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

An important aim of tobacco control is to reduce demand for the most harmful products. One product feature that could be changed to benefit public health is cigarette filter ventilation. A recent review examined the effects of cigarette filter ventilation and concluded that filter ventilation, by changing how a cigarette burns, yields more mutagens and carcinogens, and results in greater puff volume and possibly depth of inhalation, which has led to increases in peripheral lung adenocarcinomas. This study will use a novel method, the Experimental Tobacco Marketplace (ETM), to compare the impact of a narrative and a factsheet on the negative consequences of filter ventilation on tobacco product purchases. High-ventilated cigarette smokers will complete multiple scenarios in the ETM.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

Participants will complete five ETM conditions, which include six trials assessing different cigarette prices: a) high-ventilated cigarette alone, b) low-ventilated cigarette alone, c) high- and low-ventilated cigarette with high-ventilated cigarettes increasing in price, d) high- and low-ventilated cigarette with low-ventilated cigarettes increasing in price, and e) usual, high- and low-ventilated cigarette with usual cigarettes increasing in price.

Participants
Participants will be provided with study cigarettes (commercially available) however the brand will not be provided to them.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.
