New study tests if menstrual cycle timing boosts Quit-Smoking success

This study tests whether starting nicotine replacement therapy (patches, gum, or lozenges) at a specific time in the menstrual cycle helps women quit smoking. About 1,200 women who smoke daily and have regular periods will be assigned to start their quit attempt during the follicular phase, luteal phase, or at their usual time. The goal is to see if cycle-timed quitting leads to higher abstinence rates.
