Can a tailored approach help smokers quit for good?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Episodic use of NRT in the last 7 days may be considered if the participant agrees to only use study medication once randomized * Certain medications may be exclusionary and others are precautionary, to be evaluated on a case-by-case basis by study physician (See Exclusionary/Precautionary Medication List, Appendix 5) * Daily use of opioids for 30 days or more on phone screen or at screening is exclusionary, however as needed (PRN) use is allowed (i.e., 3 out of 7 days per week or less or if more frequent use in less than a month's duration) * History of hypersensitivity or allergic reaction to varenicline, NRT, or any component of these formulations as determined by the medical team * Self-report of a history or current diagnosis of schizophrenia or bipolar disorder unless cleared by study physician * Current substance use disorder (Drug Abuse Screening Test \[DAST\] score \> 3 or use \>0 in the past year and refuses to refrain from use for the duration of the study; Alcohol Use Disorders Identification Test \[USAUDIT\] score \> 24) * Individuals who report depressive symptoms in the moderately severe or severe range on the Patient Health Questionnaire - Mood Module (PHQ-9) (scores of 15 or above); or who report current suicidal ideation on the PHQ-9 * Individuals who report anxiety symptoms in the severe range on the Generalized Anxiety Disorder Scale (GAD-7) (scores of 15 or above); or meet criteria for panic syndrome on the PHQ Panic module * Psychiatric hospitalization within 1 year of screening date * Any otherwise not specified medical or psychiatric condition, illness, disorder, or concomitant medication that could compromise participant safety or treatment, as determined by the principal investigator and/or study physician * Participant considered by the investigator as unsuitable candidate for full participation in both the treatment and follow-up phases of the study
