Comparative Study
Differences in the design and sale of e-cigarettes by cigarette manufacturers and non-cigarette manufacturers in the USA.
Three categories of e-cigarette brands have emerged within the US market: e-cigarette brands developed by cigarette manufacturers, brands acquired by cigarette manufacturers and brands with no cigarette manufacturer affiliation. In the absence of federal regulatory oversight of e-cigarettes, we assessed differences in e-cigarette products and sales practices across these categories. ⋯ This exploratory study finds differences in e-cigarette products and sales practices across these three e-cigarette brand categories, with brands developed by cigarette manufacturers adopting a particularly distinctive product and sales strategy. Anticipated regulation of e-cigarettes in the USA may be influencing these product and sales decisions.

How electronic cigarettes and similar products (e-cigarettes) are defined affects how they are regulated, particularly whether existing laws for cigarettes apply, including sales and marketing, youth access, smoke-free and taxation laws. ⋯ Definitions separating e-cigarettes from other tobacco products are common. Similar to past 'Trojan horse' policies, e-cigarette policies that initially appear to restrict sales (eg, limit youth access) may actually undermine regulation if they establish local pre-emption or create definitions that divide e-cigarettes from other tobacco products. Comparable issues are raised by the European Union Tobacco Products Directive and e-cigarette regulations in other countries. Policymakers should carefully draft legislation with definitions of e-cigarettes that broadly define the products, do not require nicotine or tobacco, do not pre-empt stronger regulations and explicitly include e-cigarettes in smoke-free and taxation laws.

To explore among a diverse range of smokers and recent ex-smokers, particularly those from disadvantaged groups, how nicotine-containing products, particularly electronic cigarettes (e-cigarettes), are understood and experienced. ⋯ Different groups of smokers bring diverse expectations, requirements and concerns to their evaluations and therefore to the potential use of nicotine-containing products. The ambiguity around e-cigarettes in public health debates and medical practice is reflected in the positions and concerns of smokers. There is a need for both clear, up-to-date trustworthy information about their benefits and risks, and stronger regulation.

Randomized Controlled Trial Comparative Study
Electronic cigarette nicotine delivery can exceed that of combustible cigarettes: a preliminary report.
Electronic cigarettes (ECIGs) aerosolise a liquid that usually contains propylene glycol and/or vegetable glycerine, flavourants and the dependence-producing drug, nicotine, in various concentrations. This laboratory study examined the relationship between liquid nicotine concentration and plasma nicotine concentration and puffing behaviour in experienced ECIG users. ⋯ This study demonstrates a relationship between ECIG liquid nicotine concentration and user plasma nicotine concentration in experienced ECIG users. Nicotine delivery from some ECIGs may exceed that of a combustible cigarette. The rationale for this higher level of nicotine delivery is uncertain.

Comparative Study
Are lower income smokers more price sensitive?: the evidence from Korean cigarette tax increases.
The cigarette excise taxes and the price of a typical pack of cigarettes in Korea have not increased since 2005, and effective tax rate as a fraction of price and real price of cigarettes have both been falling. As smoking prevalence is higher among lower income people than among higher income people in Korea, the regressivity of cigarette excise taxes is often cited as a barrier to tobacco tax and price policy. While studies in several other high-income countries have shown that higher income individuals are less price sensitive, few studies have examined the differential impact of cigarette tax increases by income group in Korea. Most of the Korean literature has estimated the demand for cigarettes using time-series aggregate sales data or household level survey data, which record household cigarette expenditures rather than individual cigarette consumption. Studies using survey data often lack time-series variation and estimate cigarette demand using household expenditure data, while studies using time-series aggregate sales data lack cross-sectional variation. ⋯ The estimated price elasticities of different income groups imply that the cigarette tax and price increases in Korea would reduce smoking more in those with lower incomes. For a given price increase, the percentage reduction in cigarette consumption among smokers in the lowest income quartile is 2.5 times greater than among smokers in the top income quartile. The simulated tax burdens of different income groups show that the additional burden of a tax increase and the associated price rise is largely borne by higher income smokers.
