Summary

This trial will test if Metabolism-Informed Smoking Treatment, which tailors medication selection to nicotine metabolism, is more effective than usual care.

Who is the study for?
This trial is for daily smokers over 18 with a regular healthcare provider, who are willing to try quitting smoking after hospital discharge. They must be able to use nicotine replacement or varenicline, have phone access, a permanent address, and prescription coverage. Those too ill, in hospice care, not cognitively able to participate or already in another smoking study can't join.
What is being tested?
The MIST RCT is testing tailored smoking cessation treatments based on how fast individuals metabolize nicotine. Participants will receive either standard Nicotine Replacement Therapy or Varenicline guided by their Nicotine Metabolite Ratio (NMR), along with automated follow-up calls and tobacco coaching.
What are the potential side effects?
Possible side effects include nausea, headaches, difficulty sleeping and unusual dreams with Varenicline; skin irritation from patches and mouth/throat issues from lozenges/gum for Nicotine Replacement Therapy.

2Treatment groups
Experimental Treatment
Active Control
Group I: MIST (Metabolism-Informed Smoking Treatment)Experimental Treatment4 Interventions
At hospital discharge, participants randomized to the MIST precision care arm will receive a prescription for medication (either varenicline or NRT). Post discharge, participants will receive automated phone calls via TelASK to promote continued engagement. Medication prescriptions will be informed by nicotine metabolism (i.e., NMR result) such that faster metabolizers are prescribed varenicline and slower metabolizers are prescribed NRT.
Group II: Usual CareActive Control3 Interventions
At hospital discharge, participants randomized to the Usual Care arm will receive a prescription for medication (either varenicline or NRT). Post discharge, participants will receive automated phone calls via TelASK to promote continued engagement. Medication prescription will not be informed by nicotine metabolism.
