NCT ID NCT05515354
First seen Mar 29, 2026 · Last updated Jun 14, 2026 · Updated 13 times
Summary
This study tests whether starting a quit attempt during the first half of the menstrual cycle (follicular phase) makes it easier for women to stop smoking. About 1,200 women who smoke daily and have regular periods will use nicotine patches or gum and be randomly assigned to quit in the follicular phase, luteal phase, or without cycle timing. The goal is to see if cycle-aligned quitting boosts long-term success.
