Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a pilot sequential multiple assignment trial (SMART) to understand the optimal timing to assess response to our smoking cessation text message intervention and to measure how adding medications alone compares to adding medications and telephone coaching for those who continue to smoke. This study aims to assess the feasibility of a SMART of a proactively offered text message intervention for smokers in primary care that compares early (4 weeks) versus late (8 weeks) assessment of treatment response and the addition of nicotine replacement therapy (NRT) alone or with telephone coaching for non-responders.
