NCT07102290

Brief Summary

The goal of this pragmatic trial is to compare the effects of text messages on quitline enrollment by patients identified in electronic health records as unassisted tobacco users. The main question it aims to answer is: Do messages offering free counseling or free nicotine patches by text increase quitline enrollment? Researchers will compare if people receiving texts about free nicotine patches will have higher quitline enrollment than texts about free counseling. Participants will receive a text message stratified by quitline language and click on the toll-free number to access quitline services.
