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 relative appeal (abuse liability) of novel tobacco products, how the appeal is modulated by relative price, user type, and how novel products may substitute for one another.

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. Therefore, a priori knowledge of substitutability across novel and widely used tobacco products may forecast the impact of policies on product switching. This study will use a novel method, the Experimental Tobacco Marketplace (ETM), to characterize the relative substitutability and appeal (abuse liability) of tobacco products (e.g., conventional cigarettes, nicotine vaping products \[NVP\], heated tobacco products \[HTP\], and nicotine pouch products \[NPP\]), and how the appeal is modulated by relative price and user type. Exclusive cigarette smokers and dual cigarette/NVP users, stratified by age, will complete multiple scenarios in the ETM.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

Participants will complete seven Experimental Tobacco Marketplace conditions. Conventional cigarette price will be parametrically increased, and the purchasing of alternative products measured. Alternative products (i.e. nicotine vaping products, heated tobacco products and nicotine pouches) will be available at different prices in separate conditions (i.e., ½ market price, market price, and 2x market price).
