Testing how synthetic nicotine is processed in regular e-cig users
This Phase 1 study tests how a synthetic nicotine product is absorbed and how the body responds (so researchers can better understand nicotine effects and handling). You may be able to join if you’re generally healthy and regularly use e-cigarettes, but you’ll need to avoid certain medicines and nicotine products during the study.

What taking part in a nicotine dependence study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
