E-cigarette susceptibility among U.S. middle and high school students: National Youth Tobacco Survey Data Trend Analysis, 2014-2018.

Youth e-cigarette use has rapidly increased in the last few years. Susceptibility is a validated measure associated with future tobacco use. We examined trends in e-cigarette susceptibility across five years (2014-2018) of the National Youth Tobacco Survey among youth e-cigarette never users.

State-by-State Examination of Overdose Medical Amnesty Laws.

Introduction: Timely medical attention could decrease mortality following drug or alcohol overdose events, but overdose victims and witnesses often delay or fail to seek professional help because they fear police involvement. Statutes that provide immunity from criminal action can have an important impact on seeking timely treatment.

Methods: We systematically collected and reviewed medical amnesty laws (MALs; commonly known as "Good Samaritan laws") that are designed to encourage bystanders and others to contact authorities for assistance during overdose emergencies.

Adults' Perceptions of Nicotine Harm to Children.

Background: Given the changing landscape of tobacco products in recent years, the array of products through which children could be exposed to nicotine has grown substantially. Thus, it is particularly important to understand adults' perceptions of the harms of nicotine to children and to identify any sociodemographic factors related to inaccurate risk perceptions.

Methods: Data were drawn from 2015 to 2016 US nationally representative surveys ( = 11 959).

'No, the government doesn't need to, it's already self-regulated': a qualitative study among vape shop operators on perceptions of electronic vapor product regulation.

While the market share of electronic vapor products (EVPs), sold primarily through vape shops and other outlets, has increased rapidly, these products remained largely unregulated until 2016. This study, conducted prior to announcement of the deeming regulations, provides insights into vape shop operator attitudes toward potential government regulations of EVPs. In 2015, we conducted 37 in-person interviews of vape shop operators across nine US cities.

Affect, risk perception, and the use of cigarettes and e-cigarettes: a population study of U.S. adults.

Background: Tobacco companies argue that the decision to smoke is made by well-informed rational adults who have considered all the risks and benefits of smoking. Yet in promoting their products, the tobacco industry frequently relies on affect, portraying their products as part of a desirable lifestyle. Research examining the roles of affect and perceived risks in smoking has been scant and non-existent for novel tobacco products, such as electronic cigarettes (e-cigarettes).

Use of Nicotine in Electronic Nicotine and Non-Nicotine Delivery Systems by US Adults, 2015.

Nicotine in electronic nicotine and non-nicotine delivery systems (ENDS/ENNDS) may present a risk of harm to those with cardiovascular disease and the fetuses of pregnant women. We assessed the extent to which adult users of ENDS/ENNDS used these products with nicotine. We obtained data for this study from a national probability survey of 6051 US adults that was conducted in August and September 2015.

A Qualitative Study of Vape Shop Operators' Perceptions of Risks and Benefits of E-Cigarette Use and Attitude Toward Their Potential Regulation by the US Food and Drug Administration, Florida, Georgia, South Carolina, or North Carolina, 2015.

Introduction: Approximately 8,500 vape shops in the United States sell a variety of electronic nicotine delivery systems (ENDS). This study examined vape shop operators' perceptions of benefits and risk of ENDS use, what they perceive to be the reasons for ENDS use, their source of product information, what information they shared with customers, and the impact of existing and future regulation of ENDS on its use and on their business.

Methods: We conducted qualitative interviews with 20 vape shop operators located in Florida, Georgia, South Carolina, and North Carolina in spring 2015.
