Nicotine pouches under the microscope: do they hook new users?
NCT ID NCT07128329
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study at Johns Hopkins University is testing nicotine pouches (like Zyn) in 120 adults—60 regular smokers and 60 people who rarely use nicotine. Participants will use the pouches in two lab sessions while researchers measure how much nicotine gets into the blood, how appealing the product feels, and any withdrawal symptoms. The goal is to help the FDA understand the potential impact of these products on both users and non-users.
