Summary

This study tests Quitxt, a bilingual text and chat program designed to help young Latino adults (ages 18-29) quit smoking. About 1,200 participants will be randomly assigned to receive Quitxt or standard quit-smoking texts. Researchers will check if they've quit at 1, 3, and 6 months using self-reports and saliva tests.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Quitxt text messaging or chat program
What this could lead to
If it works, this could provide an effective, scalable way to help young Latino adults quit smoking, reducing cancer and chronic disease risks.
What could go wrong
This is a behavioral intervention trial, not a drug. Results depend on participant engagement, and the effect may be modest. The study is still recruiting, so outcomes are uncertain.
