Communicating risk differences between electronic and combusted cigarettes: the role of the FDA-mandated addiction warning and a nicotine fact sheet.

ABSTRACT: INTRODUCTION:The US Food and Drug Administration requires e-cigarettes to carry a nicotine addiction warning. This research compared the effects of messages communicating comparative risk of electronic and combusted cigarettes (CR messages) with and without the mandated warning and tested the effects of showing a nicotine fact sheet (NFS) before exposure to CR messages with warning. METHOD:In an online experiment, 1528 US adult smokers were randomised to one of four conditions: (1) three CR messages, (2) three CR messages in condition one with an addiction warning, (3) an NFS followed by the three messages in condition 2 and (4) control messages. Outcomes included message reactions and perceived effectiveness, e-cigarette-related and cigarette-related beliefs and behavioural intentions and nicotine-related beliefs. RESULTS:CR messages with and without an addiction warning did not differ. The NFS condition produced higher odds of correctly understanding the risk of nicotine and stronger beliefs that switching to e-cigarettes could reduce health risks (response efficacy) than other treatments. Compared with control, all messages made it more likely for people to report e-cigarettes are less harmful than cigarettes and increased response efficacy and switch intentions to e-cigarettes. Only NFS condition increased correct beliefs about the risk of nicotine and self-efficacy about switching to e-cigarettes. CONCLUSION:Including an addiction warning on CR messages did not reduce intentions to switch to e-cigarettes. Communicating accurate risk of nicotine together with CR messages and addiction warning increased smokers' self-efficacy beliefs about switching completely to e-cigarettes, making it a potentially promising antitobacco communication strategy.

<h4>Introduction</h4>The US Food and Drug Administration requires e-cigarettes to carry a nicotine addiction warning. This research compared the effects of messages communicating comparative risk of electronic and combusted cigarettes (CR messages) with and without the mandated warning and tested the effects of showing a nicotine fact sheet (NFS) before exposure to CR messages with warning.<h4>Method</h4>In an online experiment, 1528 US adult smokers were randomised to one of four conditions: (1 ...[more]

Project description:IntroductionEffective August 2018, the U.S. Food and Drug Administration (FDA) required that nicotine addiction warnings be placed on ads for nicotine containing e-liquids. As per FDA comments, this provision pertains to visual ads communicated via social media, raising questions about compliance within the large e-liquid promotion community on Instagram.Aims and methodsThis study examines use of warnings on promotional Instagram posts before and after provisions took effect on August 10, 2018. Netlytic was used to gather a sample of 500 promotional #eliquid and #ejuice posts from: May 2017, October 2017, March 2018, August 2018, and September 2018. The 1500 prewarning and 1000 postwarning posts were coded using content analysis. Changes in products and marketing strategies were also considered. Post volume was tracked monthly between May 2017 and February 2020.ResultsIn the prewarning period, nicotine warning statements were absent on all posts. Following August 10, 2018, FDA compliant warnings were present on 13.6% of posts. Among US-based posts, 36.4% used the warnings, with warnings more common on posts made by e-liquid brands (52.3%) and posts promoting e-liquids with nicotine (40.0%). Promotional strategies and products did not significantly change. The share of posts made by US Instagram users decreased by 11%, although total post volume continued to grow.ConclusionsMany e-liquid promotion posts on Instagram remained noncompliant with nicotine warnings after FDA provisions took effect. The large volume of international users also limited the impact of FDA-mandated warnings on the social media environment.ImplicationsFurther guidance and enforcement are needed to ensure that US e-liquid marketers on visual social media platforms adhere to current provisions, particularly for individual social media users who are sponsored by industry. The inherently global span of social media also indicates the importance of a shared approach to marketing regulations. Further work is needed to assess enforcement strategies viable for the social media environment.

Project description:ImportanceA national policy is under consideration to reduce the nicotine content of cigarettes to lower nicotine addiction potential in the United States.ObjectiveTo examine how smokers with psychiatric disorders and other vulnerabilities to tobacco addiction respond to cigarettes with reduced nicotine content.Design, setting, and participantsA multisite, double-blind, within-participant assessment of acute response to research cigarettes with nicotine content ranging from levels below a hypothesized addiction threshold to those representative of commercial cigarettes (0.4, 2.3, 5.2, and 15.8 mg/g of tobacco) at 3 academic sites included 169 daily smokers from the following 3 vulnerable populations: individuals with affective disorders (n = 56) or opioid dependence (n = 60) and socioeconomically disadvantaged women (n = 53). Data were collected from March 23, 2015, through April 25, 2016.InterventionsAfter a brief smoking abstinence, participants were exposed to the cigarettes with varying nicotine doses across fourteen 2- to 4-hour outpatient sessions.Main outcomes and measuresAddiction potential of the cigarettes was assessed using concurrent choice testing, the Cigarette Purchase Task (CPT), and validated measures of subjective effects, such as the Minnesota Nicotine Withdrawal Scale.ResultsAmong the 169 daily smokers included in the analysis (120 women [71.0%] and 49 men [29.0%]; mean [SD] age, 35.6 [11.4] years), reducing the nicotine content of cigarettes decreased the relative reinforcing effects of smoking in all 3 populations. Across populations, the 0.4-mg/g dose was chosen significantly less than the 15.8-mg/g dose in concurrent choice testing (mean [SEM] 30% [0.04%] vs 70% [0.04%]; Cohen d = 0.40; P < .001) and generated lower demand in the CPT (α = .027 [95% CI, 0.023-0.031] vs α = .019 [95% CI, 0.016-0.022]; Cohen d = 1.17; P < .001). Preference for higher over lower nicotine content cigarettes could be reversed by increasing the response cost necessary to obtain the higher dose (mean [SEM], 61% [0.02%] vs 39% [0.02%]; Cohen d = 0.40; P < .001). All doses reduced Minnesota Nicotine Withdrawal Scale total scores (range of mean decreases, 0.10-0.50; Cohen d range, 0.21-1.05; P < .001 for all), although duration of withdrawal symptoms was greater at higher doses (η2 = 0.008; dose-by-time interaction, P = .002).Conclusions and relevanceReducing the nicotine content of cigarettes may decrease their addiction potential in populations that are highly vulnerable to tobacco addiction. Smokers with psychiatric conditions and socioeconomic disadvantage are more addicted and less likely to quit and experience greater adverse health impacts. Policies to reduce these disparities are needed; reducing the nicotine content in cigarettes should be a policy focus.
