Where Do People Vape? Insights from Twitter Data

Disparities in Smokefree and Vapefree Home Rules and Smokefree Policy Attitudes Based on Housing Type and Cigarette Smoking Status, United States, 2019

This study examined variations in cigarette smoking status, home smoking and vaping rules, and attitudes toward smoking rules among U.S. adults. We analyzed data from the 2019 U.S. Census Bureau's Current Population Survey Supplements (n = 40,296 adults) and calculated weighted prevalence estimates of adult cigarette smoking based on housing type. In 2019, multi-unit housing (MUH) residents who currently smoked were predominantly residents of privately rented housing (66.9%), followed by privately owned (17.6%) and public housing (15.5%). MUH residents who currently smoked had the highest proportions of allowing smoking (26.7%) or vaping (29.1%) anywhere inside their homes and were least likely to support rules allowing smoking inside all MUH apartments or living areas. In the adjusted models, MUH residents with a current smoking status were 92% less likely to have a complete smoking ban. More than one in four MUH residents with a current smoking status allowed all smoking inside the home and supported allowing smoking inside all MUH apartment or living areas, reinforcing how MUH residents may be at higher risk of experiencing secondhand smoke or aerosol exposure, or incursions within their places of residence. Our results can inform the development, implementation, and sustainment of strategies to reduce exposures from tobacco and nicotine products in all living environments.

What Lessons Can Be Learned for the Agroecological Transition From the Use of Social Media in Preventive Medicine?

In agriculture, web-based social media are increasingly used to share knowledge concerning best practices. One goal of agroecology is to reduce the use of synthetic chemical inputs. Agroecology represents a contrast with intensive agriculture in that it better manages interactions with life forms. It is crucial to help people share their knowledge to accomplish the agroecological transition. This paper proposes an analogy between the use of social media to facilitate (1) caring for plants in the context of agroecology and (2) preventing human diseases in the context of medicine. The authors created a bibliography of scientific publications related to social media use in preventative medicine to identify best practices for social media use (and the associated drawbacks) that can be applied to develop social media dedicated to agroecology.

Exposure to secondhand aerosol from electronic cigarettes at homes: A real-life study in four European countries

Electronic cigarette (e-cigarette) use emits potentially hazardous compounds and deteriorates indoor air quality. Home is a place where e-cigarettes may frequently be used amid its increasing prohibition in public places. This study assessed the real-life scenario of bystanders' exposure to secondhand e-cigarette aerosol (SHA) at home. A one-week observational study was conducted within the TackSHS project in four countries (Greece, Italy, Spain, and the United Kingdom) in 2019 including: 1) homes of e-cigarette users living together with a non-user/non-smoker; and 2) control homes with no smokers nor e-cigarette users. Indoor airborne nicotine, PM2.5, and PM1.0 concentrations were measured as environmental markers of SHA. Biomarkers, including nicotine and its metabolites, tobacco-specific nitrosamines, propanediol, glycerol, and metals were measured in participants' saliva and urine samples. E-cigarette use characteristics, such as e-cigarette refill liquid's nicotine concentration, e-cigarette type, place of e-cigarette use at home, and frequency of ventilation, were also collected. A total of 29 e-cigarette users' homes and 21 control homes were included. The results showed that the seven-day concentrations of airborne nicotine were quantifiable in 21 (72.4 %) out of 29 e-cigarette users' homes; overall, they were quite low (geometric mean: 0.01 μg/m3; 95 % CI: 0.01-0.02 μg/m3) and were all below the limit of quantification in control homes. Seven-day concentrations of PM2.5 and PM1.0 in e-cigarette and control homes were similar. Airborne nicotine and PM concentrations did not differ according to different e-cigarette use characteristics. Non-users residing with e-cigarette users had low but significantly higher levels of cotinine, 3'-OH-cotinine and 1,2-propanediol in saliva, and cobalt in urine than non-users living in control homes. In conclusion, e-cigarette use at home created bystanders' exposure to SHA regardless of the e-cigarette use characteristics. Further studies are warranted to assess the implications of SHA exposure for smoke-free policy.

Vaping and COVID-19: Insights for Public Health and Clinical Care from Twitter

This study describes key topics of discussions on Twitter at the intersection of vaping and COVID-19 and documents public reactions to announcements from authoritative health agencies. Twitter posts containing vaping and COVID-19-related terms were collected from 1 December 2019 to 3 May 2020 (n = 23,103 posts). Text classifiers and unsupervised machine learning were used to identify topics in posts. Predominant topics included COVID-19 Respiratory Health (18.87%), COVID-19 Susceptibility (17.53%), Death (10.07%), Other COVID-19 Health Effects (9.62%), and Severity of COVID-19 (7.72%), among others. Public conversations on topics, such as Severity of COVID-19, Transmission, Susceptibility, Health Effects, Death, and Smoking cessation, were shaped by announcements from U.S. and international health agencies. Armed with the insights from this study, medical providers should be prepared to discuss vaping-related health risks with their patients in the era of COVID-19. Misconceptions around vaping as a protective behavior from, and an effective treatment against, COVID-19 should also be corrected.

For or Against Tobacco Control: Sponsored Tobacco Advocacy Messages on Facebook and Instagram

INTRODUCTION

This study explores sponsored tobacco advocacy messages on Facebook and Instagram by: (1) Examining differences in message performance metrics, funding sources, and audience characteristics of anti- and protobacco messages in the United States, and (2) Characterizing audience exposure to anti- and protobacco message themes across different age-groups and by gender.

METHODS

The analysis sample consisting of 375 tobacco-advocacy related messages on Instagram and/or Facebook in the United States from May 29, 2020 to July 26, 2020 was obtained from the Facebook Ad Library Application Programming Interface. Chi-square tests compared differences in anti- and protobacco messages by potential reach, impressions, approximate spend ($), social media platform type, average duration of delivery, type of funding sources, and audience age and gender exposure. Percentage distribution of message themes and audience exposure by age and gender were also examined.

RESULTS

Antitobacco messages (n = 334, 89.07%) exceeded protobacco messages (n = 41, 10.93%) overall. Antitobacco messages had lower potential reach, received a lower proportion of impressions, and spent a lower proportion of money per message. Protobacco advocacy was funded primarily by the tobacco industry and advocacy groups. A small fraction of antitobacco advocacy messages reached young adults and men. Among protobacco advocacy messages, a majority of messages highlighting tobacco regulations, addiction, citizen advocacy, flavors, and impact on economy reached mostly men.

CONCLUSION

Results illustrate important gaps in current sponsored antitobacco advocacy efforts, demonstrate the feasibility of monitoring sponsored tobacco advocacy on these platforms, and offer insights for future antitobacco advocacy campaigns.

IMPLICATIONS

Future antitobacco advocacy efforts on social media may consider more focused efforts in reaching young adults and men and in leveraging strategic social media analytics to improve their overall potential reach and impressions.

Topics of Nicotine-Related Discussions on Twitter: Infoveillance Study

BACKGROUND

Cultural trends in the United States, the nicotine consumer marketplace, and tobacco policies are changing.

OBJECTIVE

The goal of this study was to identify and describe nicotine-related topics of conversation authored by the public and social bots on Twitter, including any misinformation or misconceptions that health education campaigns could potentially correct.

METHODS

Twitter posts containing the term "nicotine" were obtained from September 30, 2018 to October 1, 2019. Methods were used to distinguish between posts from social bots and nonbots. Text classifiers were used to identify topics in posts (n=300,360).

RESULTS

Prevalent topics of posts included vaping, smoking, addiction, withdrawal, nicotine health risks, and quit nicotine, with mentions of going "cold turkey" and needing help in quitting. Cessation was a common topic, with mentions of quitting and stopping smoking. Social bots discussed unsubstantiated health claims including how hypnotherapy, acupuncture, magnets worn on the ears, and time spent in the sauna can help in smoking cessation.

CONCLUSIONS

Health education efforts are needed to correct unsubstantiated health claims on Twitter and ultimately direct individuals who want to quit smoking to evidence-based cessation strategies. Future interventions could be designed to follow these topics of discussions on Twitter and engage with members of the public about evidence-based cessation methods in near real time when people are contemplating cessation.

Public Support for E-Cigarette-related Policies among a Nationally Representative Sample of US Adults

Background:

The wide availability of flavored e-cigarettes and broad use of e-cigarettes in public places may contribute to the rapidly increasing rates of use among youth and young adults in the U.S. However, policies at the federal, state and local levels can address these factors.

Objective:

Assess public support for 5 e-cigarette-related policies and evaluate response patterns by demographics, tobacco use, e-cigarette harm perceptions, geographic region, and strength of state-level clean indoor air policies.

Methods:

Data were collected Oct-Dec 2018 from a nationally representative online panel of U.S. adults (n = 3211). We measured support for 5 policies: (1) a ban on the sale flavored e-cigarettes; (2) requiring tobacco products, like e-cigarettes, be kept out of view in stores where adolescents shop; and prohibiting e-cigarette use in (3) all public places; (4) restaurants; and (5) bars. Weighted, adjusted logistic regressions modeled variation in policy support.

Results:

A majority of respondents (63.3%) supported a flavor ban, with no differences in support by smoking status. Most respondents supported keeping tobacco products out of view (78.0%) and prohibiting e-cigarette use in indoor public places (82.9%), restaurants (86.5%), and bars (76.1%). In the adjusted models, current e-cigarette users had significantly lower odds of policy support compared to never users. We observed no differences in support by geographic region or strength of state-level clean indoor air policies.

Conclusion:

Results suggest high levels of public support to regulate e-cigarette flavors, marketing, and use in public places. Targeted messaging may be needed to increase support among current e-cigarette users.

Vaping: An Emerging Health Hazard

Electronic cigarettes (e-cigarettes) are electronic devices designed to vaporize chemical compounds. The device is made up of a mouthpiece, liquid tank, a heating element, and a battery. E-cigarette use may pose health risks in the form of cardiovascular and respiratory diseases. These health risks have implications to not only the primary user, but the aerosols can also cause secondhand and thirdhand injuries to others in the vicinity. Acute lung injury may also be associated with the use of e-cigarettes, but the underlying cause remains unknown. Clinicians, including hospitalists, pulmonologists, intensivists, medical examiners, pathologists, and the like, should report possible cases as the medical community continues to assess the health risks of e-cigarette use.
