ClinConnect Summary
This clinical trial is examining the withdrawal symptoms experienced by people who regularly use e-cigarettes when they stop using them for a period of time. The researchers want to better understand how nicotine, the addictive substance in e-cigarettes, affects these withdrawal symptoms. The trial is currently looking for participants between the ages of 21 and 55 who have been using nicotine-containing e-cigarettes daily for at least six months and are generally in good health. Participants should also be interested in reducing their e-cigarette use.
If you join the study, you will go through a monitored period where you will stop using e-cigarettes, and researchers will observe how you feel during this time. They will check your health and conduct some tests to make sure you are eligible and safe to participate. This study aims to help improve support for people trying to quit e-cigarettes, so your experience could contribute to better understanding and treatment options in the future.
