Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Participants were stratified by language (English, Spanish) by LADHS, then randomly assigned to one of two groups. The randomization assignment was generated by a statistician from Kick It California, and text messages were assigned to groups and delivered by LADHS.
Group 1 received a text message offering free quitline coaching. Group 2 received a text message offering free nicotine patches. The texts were sent April-May 2022 and were in English or Spanish according to patient preference. All messages contained a toll-free number to access services, which could be called directly from the text message link, but for tracking purposes different numbers were used.
The quitline, Kick It California, offered coaching to all enrolled participants. The quitline also mailed a 2-week supply of nicotine patches to all enrolled participants unless contraindicated, regardless of which text offer they received. To ensure equitable access, a second text was sent to all participants in June 2022 offering free NRT.
