Can a phone app help Spanish-Speaking smokers kick the habit?
NCT ID NCT07754448
First seen Aug 10, 2026 · Last updated Sep 16, 2026 · Updated 3 times
Summary
This pilot study tests a new smartphone app designed to help Spanish-speaking smokers quit, comparing it to proven printed booklets and a text-messaging program. About 120 Hispanic/Latinx adults who smoke at least five cigarettes a week will use one of the three approaches. The goal is to see if the app is easy to use, acceptable, and worth testing in a larger trial.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A smartphone app for smoking cessation, compared with printed booklets and a text-messaging program
- What this could lead to
- If the app proves usable and acceptable, it could offer a scalable, culturally tailored tool to help Spanish-speaking smokers quit.
- What could go wrong
- This is a small pilot focused on feasibility, not quitting success. The app may not be more effective than existing methods, and long-term abstinence is not the primary measure.
