Beyond characterizing flavors: Effects of odorless constituents (sensory additives, solvents, and synthetic nicotine) on tobacco product use behaviors from adolescence to adulthood

The NIH-funded project investigates the effects of odorless additives in tobacco products on nicotine addiction and use behaviors from adolescence to adulthood, aiming to inform FDA regulatory decisions.

Description

This project aims to determine how odorless constituents such as sweeteners, synthetic cooling agents, solvents, and synthetic nicotine alter the sensory and addictive properties of nicotine at different ages, and how early intermittent exposure to these constituents affects nicotine use behaviors in adulthood. The study uses adolescent and adult rodents to assess sensory and addictive effects, examines dopamine release, and evaluates interactive effects of these constituents on nicotine use behaviors. The outcomes will inform the FDA about the impact of odorless chemicals on nicotine addiction and the transition from adolescent to adult tobacco use.
