ClinConnect Summary

This clinical trial is studying the best way to help people quit using both cigarettes and e-cigarettes. Researchers want to find out if quitting both products at the same time (called "concurrent treatment") is more effective than quitting cigarettes first and then e-cigarettes later (called "sequential treatment"). All participants will receive a medication called varenicline, which helps reduce cravings and the pleasure people get from smoking, along with counseling and support resources to aid their quitting journey.

To be eligible for the study, participants should be between 18 and 74 years old, have been smoking cigarettes and using e-cigarettes for at least three months, and currently smoke at least five cigarettes a day. They must also be interested in quitting both products and be ready to set a quit date. However, individuals who are pregnant, breastfeeding, or using other tobacco products frequently may not be able to join. Throughout the trial, participants can expect support and guidance as they work towards quitting smoking and using e-cigarettes, which can ultimately improve their health.
