4. Text messaging and nicotine replacement therapy (TM+NRT): Brief advice + 12 week personalized, tailored text messaging program + 2 weeks of nicotine patches and/or lozenges mailed to subject. Rationale: As above, in order to test the effect of text messaging on medication adherence, we need to have treatment groups receiving medication and medication plus text messaging. Text messaging has been shown to increase medication adherence in other conditions and medication adherence is suboptimal among users of smoking cessation medications. Integrating text messaging within healthcare systems offers opportunities to coordinate with pharmacotherapy and this 4 group design allows us to test the effect of text messaging alone on smoking outcomes and the effect of text messaging on NRT use.
