E-Cigarette Use and Depression Among American Indian Adults Who Smoke.

Objective: This study examined the association of e-cigarette use status and history of depression among American Indian (AI) adults who smoke.

Method: We conducted a secondary data analysis using survey data from 375 AI adult smokers collected in 2016 at a tribally operated healthcare facility in northeast Oklahoma. Multivariable logistic regression was used to estimate the association between e-cigarette use and self-reported history of depression while adjusting for potential confounders.

The impact of non-tobacco e-cigarette flavoring on e-cigarette uptake, cigarette smoking reduction, and cessation: A secondary analysis of a nationwide clinical trial.

Introduction: The impact of e-cigarette flavoring on e-cigarette uptake and switching to e-cigarettes among adults who smoke is critical to e-cigarette regulation in the United Sates. The purpose of this secondary analysis was to assess the impact of e-cigarette flavoring choice on e-cigarette uptake and changes in cigarette smoking in a large nationwide trial of e-cigarette provision in the United States.

Methods: A free four-week supply of e-cigarettes was provided with minimal instructions to use to adults who smoke (N = 427).

E-Cigarette switching and financial incentives to promote combustible cigarette cessation among adults accessing shelter services: A pilot study.

Background: Smoking prevalence among U.S. adults experiencing homelessness is ≥70 %.

E-cigarette market share by nicotine claims.

Background: Nicotine forms (salt vs. freebase) and isomers (synthetic vs. tobacco-derived) are key characteristics of e-cigarettes that manufacturers manipulate, and "tobacco-free" claims may have served to attract new consumers and increase their intention to use.
