Acute Pharmacokinetic and Pharmacodynamic Effects of “Tobacco-Free” Oral Nicotine Pouches in Smokers
This research is being done to learn more about the short-term effects of oral nicotine pouches, including subjective and cardiovascular effects and also to understand nicotine pharmacokinetics (or how the drug moves through your body) from nicotine pouches in comparison to tobacco cigarettes. Nicotine pouches are becoming more popular and are widely available in retail stores such as tobacco shops and gas stations. However, to date, there has not been much research done to understand the effects of these pouches in tobacco cigarette smokers.

People aged 18-65 years who are current daily tobacco smokers with an interest in quitting may join. The study will take place on the Johns Hopkins Bayview Medical Center campus at the Johns Hopkins Behavioral Pharmacology Research Unit. If you qualify and choose to take part in this study, compensation of up to $615 can be earned for completing all portions of the study procedures and following all study requirements.
Study Participation consists of:
21 experimental test sessions over the course of 6 weeks. The study will be completed in 3 phases, each lasting two weeks. Study weeks 1, 3, and 5 will be baseline weeks, during which you will smoke cigarettes as you normally would. Study weeks 2, 4, and 6 will be simulated quit attempt weeks, during which you will be asked to attempt to quit smoking cigarettes. You will be at the BPRU for up to 2 hours during each study visit, though most sessions will be about 30 minutes.
