The purpose of this study is to better understand what happens when someone attempts to quit smoking.

Investigators will provide participants with nicotine patches, smoking cessation treatment that will include brief counseling sessions (10-15 minutes each), and text messages sent to their provided study phone throughout the day. These messages will be short (1-3 minutes long) and will ask participants to do things like focus on the present moment, pay attention to their breathing, and be aware of their current thoughts. Participants will be asked to wear equipment throughout the day that will measure their physiology and smoking behavior. Mobile Health (mHealth) is a general term for the use of mobile phones and other wireless technology in medical care.

The key outcome and hypothesized mechanisms (i.e., lapse and stress) will be measured objectively and automatically using AutoSense. AutoSense is a type of human sensing technology that allows investigators to detect smoking behavior and stress objectively through a chest strap and wrist bands worn by participants. Ecological momentary assessment (EMA) will assess acute precipitants such as negative affect, craving, self-efficacy, motivation, alcohol consumption, etc. Questionnaires will assess other predictors and mechanisms.
