"Smoker" and "Vaper" identity in people who use both cigarettes and E-cigarettes: Changes over time and associations with smoking behaviors.

Background: Individuals who use both cigarettes and e-cigarettes may have multiple nicotine product use self-identities, each of which may be associated with patterns of use, including cessation.

Objectives: This study examined changes in "smoker" and "vaper" identities and product use behaviors over one year among adults who used both cigarettes and e-cigarettes. We hypothesized that stronger baseline vaping identities would be associated with higher odds of smoking cessation, and stronger baseline smoking identities would be associated with continued cigarette use.

Prior Authorization Requirements and Medicaid Enrollees' Use of Tobacco Cessation Medications, Colorado, 2023.

Despite tobacco cessation medications being a first-line treatment for quitting smoking, a majority of Medicaid programs require health care providers to obtain prior authorization before prescribing them. We examined the impact of Colorado's Medicaid program removing its prior authorization requirement for these drugs on their use and estimated the additional number of Coloradoans who used these therapies in 2023 because of the policy change. The findings indicate that these requirements decrease low-income people's use of these medications.

Pleasure and Satisfaction as Predictors of Future Cigarette and E-cigarette Use: A Novel Two-Stage Modeling Approach.

Introduction: Subjective experience of e-cigarettes may be an important factor in helping people who use combustible cigarettes switch completely to e-cigarettes to reduce harm from smoking. This paper describes a novel two-stage analysis using pleasure and satisfaction responses from ecological momentary assessments (EMA) of both cigarette and e-cigarette use to predict future cigarette and e-cigarette tobacco use.

Aims And Methods: This observational study included adult users of cigarettes and e-cigarettes who provided 7 days of EMA, capturing cigarette and e-cigarette use, followed by biweekly reports of cigarette and e-cigarette use over 1 year.

Smoking cessation, harm reduction, and biomarkers protocols in the PhenX Toolkit: Tools for standardized data collection.

The use of standard protocols in studies supports consistent data collection, improves data quality, and facilitates cross-study analyses. Funded by the National Institutes of Health, the PhenX (consensus measures for otypes and eposures) Toolkit is a catalog of recommended measurement protocols that address a wide range of research topics and are suitable for inclusion in a variety of study designs. In 2020, a PhenX Working Group of smoking cessation experts followed a well-established consensus process to identify and recommend measurement protocols suitable for inclusion in smoking cessation and smoking harm reduction studies.
