What this research studies

You would be an adult smoker (21+) taking varenicline and may also be randomly assigned to use nicotine lozenges and a smartphone-based medication adherence program. The trial uses a factorial design so participants can receive one, both, or neither of the additional supports. The smartphone program provides reminders and tips to help with taking medication and handling cravings, and researchers will track your smoking status with follow-up visits and biochemical tests. The study aims to see whether adding lozenges and phone support improves quit rates compared with varenicline alone.

Who could benefit from this research

Good fit: Adults aged 21 or older who smoke, want help quitting, are willing to take varenicline, and have access to a smartphone are ideal candidates.

Not a fit: People who cannot take varenicline, are under age 21, or do not have smartphone access may not be eligible or benefit from this program.

Why it matters

Potential benefit: If successful, this approach could help more people quit by reducing cravings and improving use of medication.

How similar studies have performed: Meta-analyses show that varenicline plus the nicotine patch can boost quit rates, but varenicline combined with nicotine lozenges has not been tested in randomized trials and the smartphone adherence approach is relatively new.
