Vape shop and consumer activity during COVID-19 non-essential business closures in the USA

Awareness and perceived behaviour changes following the New York state vaping flavour ban, 2021-2022

SIGNIFICANCE

Despite an electronic cigarette (e-cigarette) flavour ban in New York (NY) since May 2020, most youth who vape continue to report vaping restricted flavours. This study aims to examine youth awareness and perceived behaviour change associated with the NY vaping flavour ban.

METHODS

NY cross-sectional data from 2021 and 2022 ITC Youth Survey were combined and analysed (N=1014). Weighted analyses were used to describe awareness and understanding of the e-cigarette flavour ban, as well as changes in tobacco use behaviour.

RESULTS

Only 0.9% (n=8) of NY youth understood the flavour ban, in that they were both aware of the flavour ban in all stores and accurately reported that all non-tobacco flavours were banned. Awareness and understanding of the flavour ban differed by vaping status (p<0.01): respondents who had vaped in the past 12 months or 30 days were more likely (adjusted OR (aOR)=2.15, 95% CI 1.34, 3.45; aOR=2.07, 95% CI 1.17, 3.64, respectively) to be aware of the flavour ban but misunderstand the stores or flavours included. Of the majority of youth who reported awareness of a flavour ban and vaped (n=122) or smoked (n=78) in the past 12 months reported no changes in behaviour (64.0% and 69.7%, respectively).

CONCLUSIONS

Less than one-third of NY youth, regardless of vaping status, reported that an e-cigarette flavour ban was present where they live. Further, most youth who were aware of the ban misunderstood which flavours were restricted and/or that the ban applied to all stores that sold e-cigarettes. Increased enforcement and educational efforts could improve awareness and understanding of the NY e-cigarette flavour ban.

Associations between tobacco 21 and state flavour restrictions with young adult tobacco use

BACKGROUND

States have recently enacted tobacco-related age and flavour restrictions in addition to federal T21 laws. Little is known about the independent effects of these policies on young adult tobacco use.

METHODS

Linking 2011-2022 Behavioural Risk Factor Surveillance System data on 2 696 870, 18-59 years from 50 states and DC with policy data, we conducted probit regression models to evaluate the associations between state and federal T21 laws and state flavour restrictions with cigarettes, electronic nicotine delivery system (ENDS) and smokeless tobacco use. Models were adjusted for sociodemographics, additional tobacco policies, COVID-19-related factors, year and state. We tested two-way and three-way interactions between age, state T21 and federal T21 laws.

RESULTS

Although we did not find evidence that state T21 laws were associated with cigarette, smokeless tobacco or ENDS use overall, the federal T21 law was associated with lower use of all three tobacco products by 0.39-0.92 percentage points. State flavour restrictions were associated with lower use of cigarettes by 0.68 (-1.27 to -0.09) and ENDS by 0.56 (-1.11 to -0.00) percentage points, but not with smokeless tobacco. A three-way interaction revealed that state and federal T21 laws together were associated with a lower prevalence of ENDS use among 18-20 years, but there were no differences in cigarette use from both policies combined versus either alone.

CONCLUSION

State and federal T21 laws are broadly effective at reducing adult tobacco use, while state flavour restrictions specifically lower use of cigarettes and ENDS.

Derived psychoactive cannabis products and 4/20 specials: An assessment of popular brands and retail price discounts in Fort Worth, Texas, 2023

BACKGROUND

Retail sales of derived psychoactive cannabis products (DPCPs) have increased in the U.S. since passing the 2018 Farm Bill and is unregulated in most states. This study investigated the types and commonly sold brands of DPCPs as well as promotional pricing on April 20th, a day associated with cannabis use.

METHODS

On April 19-20, 2023, investigators conducted telephone surveys with 98 retail stores that sold DPCPs in Fort Worth, Texas (where the market was largely unregulated).

RESULTS

Delta-8, Delta-9, and Delta-10 THC products were widely available, with 97%, 72%, and 82% of stores selling each type, respectively. Fifteen additional DPCPs were identified, and selling blends containing multiple types of THC was common. Frequently sold brands included Cake, Medusa/Modus, Torch, Urb, Kik, Tyson, 3Chi, Casper, Hidden Hills, Esco Bars, Happi, Hometown Hero, STNR, Bomb Bars, Baked, Hi On Nature, Looper, and Space God. Overall, 45% reported having 4/20 specials discounting prices on DPCPs, smoking devices/accessories, or everything in the store. Several stores also sponsored 4/20 promotional events including free THC gummies and "live delta demos where people can test cartridges and try smoking flower in the store."

CONCLUSIONS

Findings highlight the growing complexity of the DPCP market, including numerous different intoxicating compounds and blends. Policymakers, researchers, and public health professionals should consider these complexities, as well as the commonly sold brands, when developing strategies to regulate DPCPs and protect consumer safety. Pricing policies may be an especially important form of harm reduction during events associated with heavy cannabis use, including 4/20.

A qualitative study on the influence of COVID-19 on smoking behaviors through changing social and physical contexts

Globally, COVID-19 has been a major societal stressor and disrupted social and physical environments for many. Elucidating mechanisms through which societal disruptions influence smoking behavior has implications for future tobacco control efforts. Qualitative interviews were conducted among 38 adults who smoked combustible cigarettes in 2020 and 2021. The majority were women (75.7%), identified as Black (56.8%), were employed (61.3%), had a smoke-free home (66.7%) and lived in a small metro or rural (79.0%) county, primarily in rural southwest Georgia. Participants reported more time at home, increased isolation and less socializing, changed work and financial situations and altered household and family contexts. The vast majority of participants smoked more at some point during the pandemic with about half of these continuing to smoke more at the time of the interview. More time at home, multiple sources of stress and boredom were the main reasons for increased smoking. Decreases in smoking were attributed to financial strain, smoke-free home rules and nonsmoking family members, concerns about COVID-19 and less socializing with friends who smoke. Future tobacco control efforts during societal stressors such as pandemics should take into account specific psychosocial and environmental influences in attempts to minimize negative changes to smoking patterns.

IQOS marketing strategies at point-of-sales: a cross-sectional survey with retailers

BACKGROUND

The point-of-sale (POS) is adapting to marketing restrictions, societal changes and the inclusion of new products, such as heated tobacco products (eg, Philip Morris International's (PMI) IQOS device and HEETS sticks). We aimed to assess (1) PMI's influences on IQOS/HEETS POS marketing and (2) the implications of the new legislation (POS display ban and plain packaging) for retailers.

METHODS

A cross-sectional survey of 43 IQOS/HEETS POS owners/managers in five Israeli cities assessed POS and participant characteristics, marketing strategies, attitudes towards IQOS, and POS implications of the legislation and COVID-19, including industry reactions. Bivariate analysis explored differences between POS selling of the IQOS device versus POS selling of HEETS only.

RESULTS

A higher proportion of those carrying IQOS (n=15) (vs HEETS only) had special displays (100% vs 17.9%, p<0.001) and interacted with specific IQOS salespersons (73.3% vs 28.6%, p=0.013). Common promotions were financial incentives based on HEETS sales for retailers (37.5%) and price discounts on HEETS for customers (48.7%). Most indicated positive attitudes towards IQOS (72.1%; eg, 'less harmful'), opposition to the legislation (62.7%), limited government assistance to implement the legislation (62.8%), and industry provision of display cases and/or signage to comply with the legislation (67.4%).

CONCLUSION

PMI uses similar tactics to promote IQOS at POS as they previously used for combustible products, including direct promotional activities with retailers, and circumvented legislation by using special displays and signage. Governments need to ban these measures and support retailers with clear practical guidance regarding the implementation of marketing restrictions at POS.

How consumer behaviours changed in response to COVID-19 lockdown stringency measures: A case study of Walmart

Walmart is a major player in the US retail sector and was one of the grocery corporations that bucked the trend of declining retail sales at the start of the COVID-19 pandemic in 2020. Particularly in the initial stages of the pandemic, governance priorities focussed on restricting the movement of people and closing non-essential retailers and service providers to slow the spread of the virus and keep people safe. This paper investigates the impact of non-pharmaceutical interventions, in the form of lockdown stringency measures, on consumer purchasing behaviours for essential goods over the onset of the pandemic. Focussing on both instore and online sales outcomes for Walmart in the US, we examine changes between pre-pandemic trends in two different sales outcomes, sales transactions and total spend, and trends in 2020. We then employ a series of multi-level regression models to estimate the impact that imposed stringency measures had on these sales outcomes, at both national and state level. Results indicate that nationally consumers were making fewer, larger physical shopping trips and huge increases in online sales was seen ubiquitously across the country. Novel and expansive insights from such a wide-spread retailer, such as Walmart, can help retailers, stakeholders and policy makers understand changing consumption trends to inform business strategies and resilience planning for the future. Furthermore, this study highlighted the value of examining spatial trends in sales outcomes and hopes to influence greater consideration of this in future research.

COVID-19 Restrictions and Adolescent Cigarette and E-cigarette Use in California

INTRODUCTION

Shelter-in-place orders altered facilitators and barriers to tobacco use (e.g., outlet closures, restricted social gatherings). This study examined whether the duration of time in shelter in place and compliance with different shelter-in-place orders influenced adolescent cigarette and E-cigarette use and how the use may differ by demographic characteristics.

METHODS

Shelter-in-place policy data obtained from government websites were merged with cross-sectional 2020 survey data on adolescents in California. Treatment variables included the proportion of time in shelter in place and self-reported compliance with shelter-in-place orders (for essential businesses and retail spaces and social and outdoor contexts). Multilevel logit models for dichotomous past 6-month cigarette and E-cigarette use and multilevel negative binomial regression models for past 6-month frequency of use were used. Moderation analyses were conducted on demographic measures. The sample included 1,196 adolescents (mean age=15.8 years, age range=13-19 years, 49.2% female, 50.0% White). Analyses were conducted in 2022.

RESULTS

No associations were found between the proportion of time in shelter in place and outcomes. Shelter-in-place compliance with essential business and retail space orders was associated with lower odds of using cigarettes and E-cigarettes in the past 6 months. Compliance with social and outdoor context-related orders were associated with lower odds of using E-cigarettes and fewer days using cigarettes and E-cigarettes. Being aged ≥18 years moderated the associations between essential business/retail space and social/outdoor context-related shelter-in-place compliance orders and past 6-month frequency of cigarette smoking.

CONCLUSIONS

Findings support tailored interventions for less compliant and older adolescents for future pandemic mitigation measures.

Exploring young adults' e-cigarette use behavior during COVID-19

INTRODUCTION

Changes in daily life related to COVID-19 have impacted e-cigarette use, particularly in young adults. This cross-sectional mixed-methods study explored young adults' perceptions regarding how COVID-19 influenced their e-cigarette use.

METHODS

We analyzed Fall 2020 survey data from 726 past 6-month e-cigarette users (mean age=24.15 years, 51.1% female, 35.5% sexual minority, 4.4% Black, 10.2% Asian, 12.1% Hispanic) and Spring 2021 semi-structured interview data among a subset of 40 participants (mean age=26.30 years, 35.0% female, 45.0% sexual minority, 5.0% Black, 22.5% Asian, 12.5% Hispanic). Participants were drawn from 6 metropolitan statistical areas with varied tobacco and cannabis legislative contexts.

RESULTS

Among survey participants, 44.4% also smoked cigarettes, 54.0% other tobacco products, and 60.1% used cannabis. They reported various changes in their daily lives, including changes in the nature and/or status of employment (e.g. 15.3% were laid off, 72.8% experienced household income loss). Regarding changes in e-cigarette use since COVID-19, 22.6% tried to cut down and 16.0% tried to quit. Interview participants commonly indicated that they increased their use due to stress, boredom, changes in accessibility, and/or changes to daily environment that made e-cigarette use more feasible.

CONCLUSIONS

Results highlight the importance of promoting opportunities for young adults to build relationships to decrease stress, foster a sense of belonging, and increase quality of life (e.g. increasing the accessibility to mental health and social support services, intentionally engaging young adults in pandemic-appropriate community-building and extracurricular activities). This research may help to inform future e-cigarette cessation interventions that consider the unique challenges of societal stressors, such as pandemics.

Changes in electronic cigarette use among U.S. Adults by cigarette smoking status, socciodemographics, and subjective depression, 2019-2020

E-cigarette use increased from 2017 to 2019 and then declined in 2020 among U.S. adults. It is important to understand whether the decline differed by smoking status and sociodemographic groups and whether daily e-cigarette use has subsequently changed. This study estimated e-cigarette use prevalence in 2019 and 2020 by analyzing the pooled National Health Interview Survey (n = 63,565) in 2022. Multivariable logistics regressions were performed to examine biannual change in current and daily e-cigarette use, overall and stratified by cigarette smoking status, sociodemographic factors, and subjective depression frequency. Among US adults, change in current e-cigarette use during 2019-2020 differed by smoking status (cigarette smoking status × year, p =.01) and race/ethnicity (race/ethnicity × year, p =.03). Current e-cigarette use prevalence decreased among current cigarette smokers (11.7 % to 8.0 %, p = 0.0001) but not among former or never smokers, and among Non-Hispanic White adults (5.1 % to 4.2 %, p = 0.04) and Non-Hispanic Black adults (3.4 % to 1.6 %, p = 0.0003) but not among other racial and ethnic groups. Current e-cigarette use also declined among those 25-64 years old but not among young adults 18-24 years old. Daily e-cigarette use did not significantly change during 2019-2020 in the overall sample (2.3 % to 2.0 %, p = 0.10), but declined among adults who were Non-Hispanic Black (2.4 % to 0.9 %, p = 0.0007), aged 35-44 years, and lived below the federal poverty level. Adults with monthly depressive episodes (vs without) continued to have a higher prevalence of current (7.0 % vs 3.0 %) and daily e-cigarette use (3.6 % vs 1.6 %) in 2020. Continuous monitoring of cross-population differences in adult e-cigarette use is warranted.

Associations between living in localities with e-cigarette sales restrictions and e-cigarette use change among young adults in Los Angeles County

INTRODUCTION

Local e-cigarette sales restrictions (ESRs) may impact e-cigarette use. This study examined the associations between living in localities with various ESR policies and changes in e-cigarette use among young adults in Los Angeles (LA) County, California, USA.

METHODS

Data were from a cohort of LA County young adults (18-21 years; n=2100) who completed two waves of surveys (Fall 2018-Summer 2019 and Summer-Fall 2020). Local flavoured (n=9) and comprehensive (n=2) ESRs in LA County implemented between June 2019 and May 2020 were identified, coded and merged with the baseline data. Multivariable logistic regressions were used to examine the associations between living in ESR localities and e-cigarette use at follow-up, controlling for covariates and stratified by cigarette smoking at baseline.

RESULTS

Overall, 20.9% and 14.3% of participants lived in localities with flavoured and comprehensive ESRs, respectively. Participants who were non-Hispanic, had higher socioeconomic statuses and were currently using e-cigarettes were generally more likely to live in ESR localities than their counterparts. The associations between living in ESR localities and e-cigarette use at follow-up were not found among baseline non-e-cigarette users regardless of their cigarette smoking status; a positive relationship was found among baseline e-cigarette users who also smoked cigarettes but not among non-smokers.

DISCUSSION

Participants who lived in localities with various ESR policies were different in their baseline e-cigarette use and socioeconomic backgrounds. Future research examining the potential impact of ESRs on e-cigarette use change should consider the localities' overall sociodemographic and tobacco-using characteristics and individuals' cigarette smoking histories.

"I don't know whose mouth has been on this": youth nicotine and cannabis vaping practices in the context of the COVID-19 pandemic

Early COVID-19 safety protocols urged physical and social distancing, resulting in minimal contact with others. As social contexts are central to vaping among youth, we used semi-structured interviews to describe how youth who vape are making sense of their use practices and adaptations. The qualitative analyses revealed changes in vaping frequency and access, social isolation shaping substance- and product-specific use, and motivations and outcomes of dual use of nicotine and cannabis which were closely linked to the pandemic. The findings indicate variation of youth vaping experiences within the early stages of the pandemic that should be attended to in future studies.

Tobacco product use and the risks of SARS-CoV-2 infection and COVID-19: current understanding and recommendations for future research

Heterogeneity in the clinical presentation of SARS-CoV-2 infection and COVID-19 progression underscores the urgent need to identify individual-level susceptibility factors that affect infection vulnerability and disease severity. Tobacco product use is a potential susceptibility factor. In this Personal View, we provide an overview of the findings of peer-reviewed, published studies relating tobacco product use to SARS-CoV-2 infection and COVID-19 outcomes, with most studies focusing on cigarette smoking in adults. Findings pertaining to the effects of tobacco product use on the incidence of SARS-CoV-2 infection are inconsistent. However, evidence supports a role for cigarette smoking in increasing the risk of poor COVID-19 outcomes, including hospital admission, progression in disease severity, and COVID-19-related mortality. We discuss the potential effects of tobacco use behaviour on SARS-CoV-2 transmission and infection, and highlight the pathophysiological changes associated with cigarette smoking that could promote SARS-CoV-2 infection and increased disease severity. We consider the biological mechanisms by which nicotine and other tobacco product constituents might affect immune and inflammatory responses to SARS-CoV-2 infection. Finally, we identify current knowledge gaps and suggest priorities for research to address acute and post-acute health outcomes of COVID-19 during and after the pandemic.

The COVID‑19 pandemic and the consumption of tobacco and nicotine-containing products: a literature review

The fight against the COVID‑19 pandemic has led to the implementation of unprecedented measures in countries, including self-isolation, which have had a significant impact on people’s behavior and could lead to a change in the consumption of tobacco and nicotine-containing products. This article provides an overview of studies evaluating smoking behavior change and its impact on the prevalence of tobacco and nicotine use in the community at the start of the pandemic.

Methods. The review included 31 published studies with data on smoking from more than 250,000 people from 24 countries that examined the following aspects of the problem: the association of smoking with COVID‑19 outcomes, identification of factors influencing smoking behavior at the beginning of the COVID‑19 pandemic, changing prevalence of tobacco and nicotine consumption at the start of the COVID‑19 pandemic, tobacco company actions during the pandemic, impact of misinformation about the association of smoking with COVID‑19 on consumers of tobacco and nicotine products, government actions to reduce the sale of tobacco and nicotine products during the pandemic time.

Findings. All researchers identified mixed responses from consumers of tobacco and nicotine-containing products early in the pandemic. In equal proportions, smokers increased their tobacco/nicotine intake or reduced their smoking intensity. To a lesser extent, consumers quit smoking, but there were respondents who reported starting smoking due to the COVID‑19 pandemic.

Conclusion. Monitoring the prevalence of consumption of tobacco and nicotine-containing products and the causes influencing it in the early periods of the COVID‑19 pandemic made it possible to identify additional effective measures, the implementation of which can prevent the growth of tobacco and nicotine consumption in such situations.

The Reshaping of the E-Cigarette Retail Environment: Its Evolution and Public Health Concerns

E-cigarette use represents a public health controversy in the US and globally. Despite the potential of e-cigarettes to support cigarette cessation, their use increases health risks and risk for addiction, particularly in young people. Various federal, state, and local laws have impacted tobacco retail in general and e-cigarettes in particular. In the US, 2019–2020 federal laws increased in the minimum legal sales age for tobacco to 21 and banned flavored cartridge-based e-cigarettes. Many states and localities were early adopters of Tobacco 21 and implemented more comprehensive flavor restrictions than the federal ban. Meanwhile, cannabis retail is increasingly being legalized in the US—while cannabis-based product regulation has notable gaps at the federal, state, and local levels. These regulatory complexities have impacted specialized retailers selling e-cigarettes, including “vape shops” that exclusively sell e-cigarettes, “smoke shops” that sell e-cigarettes and other tobacco (and potentially CBD/THC and other un- or under-regulated products), and online retail. This commentary outlines public health concerns related to: (1) youth access; (2) consumer exposure to a broader range of tobacco products and marketing in retail settings where they may seek products to aid in cigarette cessation (i.e., such broad product exposure could hinder cessation attempts); (3) consumer exposure to un-/under-regulated products (e.g., delta-8-THC, kratom); and (4) federal, state, and local regulations being undermined by consumer access to prohibited products online and via the mail. These concerns underscore the need for ongoing surveillance of how retailers and consumers respond to regulations.

Assessment of worker chemical exposures in California vape shops

E-cigarettes are battery-operated devices that heat a liquid mixture to make an aerosol that is inhaled, or vaped, by the user. Vape shops are retail environments designed to fulfill customer demand for diverse e-liquid flavors and hardware options, which create unique worker exposure concerns. To characterize exposures to vape shop workers, especially to flavoring chemicals associated with known respiratory toxicity, this study recruited vape shops from the San Francisco Bay Area. In six shops, we measured air concentrations for volatile organic compounds, formaldehyde, flavoring chemicals, and nicotine in personal and/or area samples; analyzed components of e-liquids vaped during field visits; and assessed metals on surface wipe samples. Interviews and observations were conducted over the course of a workday in the same six shops and interviews were performed in an additional six where sampling was not conducted. Detections of the alpha-diketone butter flavoring chemicals diacetyl and/or 2,3-pentanedione were common: in the headspace of purchased e-liquids (18 of 26 samples), in personal air samples (5 of 16), and in area air samples (2 of 6 shops). Two exceedances of recommended exposure limits for 2,3-pentanedione (a short-term exposure limit and an 8-hr time-weighted average) were measured in personal air samples. Other compounds detected in the area and personal air samples included substitutes for diacetyl and 2,3-pentanedione (acetoin and 2,3-hexanedione) and compounds that may be contaminants or impurities. Furthermore, a large variety (82) of other flavoring chemicals were detected in area air samples. None of the 12 shops interviewed had a health and safety program. Six shops reported no use of any personal protective equipment (PPE) (e.g., gloves, chemical resistant aprons, eye protection) and the others stated occasional use; however, no PPE use was observed during any field investigation day. Recommendations were provided to shops that included making improvements to ventilation, hygiene, use of personal protective equipment, and, if possible, avoidance of products containing the alpha-diketone flavoring chemicals. Future research is needed to evaluate the long-term health risks among workers in the vape shop retail industry and for e-cigarette use generally. Specific areas include further characterizing e-liquid constituents and emissions, evaluating ingredient health risks, evaluating the contributions of different routes of exposure (dermal, inhalation, and ingestion), and determining effective exposure mitigation measures.

The Impact of Recent Tobacco Regulations and COVID-19 Restrictions and Implications for Future E-Cigarette Retail: Perspectives from Vape and Vape-and-Smoke Shop Merchants

BACKGROUND

Tobacco regulations and COVID-19 state orders have substantially impacted vape retail. This study assessed vape retailers' perspectives regarding regulations and future retail activities.

METHODS

In March-June 2021, 60 owners or managers of vape or vape-and-smoke shops (n = 34 vs. n = 26) in six US metropolitan areas completed an online survey assessing: (1) current and future promotional strategies and product offerings; and (2) experiences with federal minimum legal sales age (T21) policies, the federal flavored e-cigarette ban, and COVID-19-related orders. Quantitative data were analyzed descriptively; qualitative responses to open-ended questions were thematically analyzed.

RESULTS

Most participants had websites (65.0%), used social media for promotion (71.7%), offered curbside pickup (51.7%), and sold CBD (e.g., 73.3% vape products, 80.0% other); many also sold other tobacco products. Knowledge varied regarding state/local policies in effect before federal policies. Participants perceived tobacco regulations and COVID-19 orders as somewhat easy to understand/implement and perceived noncompliance consequences as somewhat severe. Qualitative themes indicated concerns regarding regulations' negative impacts (e.g., sales/customer loss, customers switching to combustibles), insufficient evidence base, challenges explaining regulations to customers, and concerns about future regulatory actions.

CONCLUSIONS

Surveillance of tobacco retail, consumer behavior, and regulatory compliance is warranted as policies regarding nicotine and cannabis continue evolving.

Smoking and E-Cigarette Use Among U.S. Adults During the COVID-19 Pandemic

INTRODUCTION

With concerns about tobacco use being a risk factor for severe disease from COVID-19, understanding nicotine- and tobacco-use patterns is important for preventive efforts. This study aims to understand changes in combustible cigarette and E-cigarette use among U.S. adults.

METHODS

In August 2020, a cross-sectional survey of a nationally representative sample of adults aged ≥18 years in the National Opinion Research Center's AmeriSpeak Panel who reported past 6-month use of combustible cigarettes or E-cigarettes was conducted. Multivariable logistic regression assessed the factors associated with increased product use and quit attempts since hearing about COVID-19.

RESULTS

A total of 1,024 past 6-month cigarette smokers/E-cigarette users were surveyed. Among cigarette smokers, 45% reported no change in cigarette smoking, and 33% reported increased cigarette smoking since hearing about COVID-19. Higher stress was associated with increased cigarette smoking. Among E-cigarette users, 41% reported no change in E-cigarette use, and 23% reported increasing E-cigarette use. A total of 26% of cigarette smokers and 41% of E-cigarette users tried to quit because of COVID-19. Higher perceived risk of COVID-19 was associated with attempts to quit combustible cigarettes (AOR=2.37, 95% CI=1.59, 3.55) and E-cigarettes (AOR=3.14, 95% CI=1.73, 5.70).

CONCLUSIONS

Cigarette and E-cigarette use patterns varied in response to the COVID-19 pandemic. Most cigarette smokers and E-cigarette users perceived product use as increasing COVID-19‒related health risks, and this was associated with attempts to quit. Some cigarette smokers, especially those reporting higher stress, increased product use. Proactive provision of cessation support to smokers and E-cigarette users may help mitigate the stress-related increases in product use during the COVID-19 pandemic.

Decreases in smoking and vaping during COVID-19 stay-at-home orders among a cohort of young adults in the United States

In Spring 2020, most US states and territories implemented stay-at-home orders to slow transmission of the novel coronavirus SARS-CoV2, the cause of COVID-19. Little is known about the impact of stay-at-home orders on tobacco and nicotine use including among young adults. The current study examined participants (N = 1727) completing three recent survey waves from a longitudinal cohort of young adults recruited in 2010 from North Carolina and Virginia, USA: Wave 13 (Spring 2019), Wave 14 (Fall 2019), and Wave 15 (Spring 2020) to assess changes in cigarette and e-cigarette use. We conducted logistic regression analyses to compare the odds that participants reported smoking or vaping in Wave 14 relative to Wave 13 to establish if there was a trend of use pre-pandemic. Then, we conducted logistic regression analyses to compare the odds that participants reported smoking or vaping in Wave 15 relative to Wave 14 to determine the impact of COVID-19 stay-at-home orders. When comparing the odds of reporting tobacco use at Wave 14 to Wave 13, no differences emerged (p > 0.05). However, when comparing tobacco use at Wave 15 to Wave 14, participants had 40% lower odds of reporting past 30-day cigarette use (p = 0.02) and 50% lower odds of reporting past 30-day e-cigarette use (p < 0.01). The current study provides initial evidence that young adults may have reduced their tobacco and nicotine use during the stay-at-home orders. However, more work is needed to determine the long-term impact of the COVID-19 pandemic on tobacco use and cessation in this population.

What matters: non-pharmaceutical interventions for COVID-19 in Europe

OBJECTIVES

The purpose of this study is to describe the situation of COVID-19 in European countries and to identify important factors related to prevention and control.

METHODS

We obtained data from World Health Statistics 2020 and the Institute for Health Metrics and Evaluation (IHME). We calculated the Rt values of 51 countries in Europe under different prevention and control measures. We used lasso regression to screen factors associated with morbidity and mortality. For the selected variables, we used quantile regression to analyse the relevant influencing factors in countries with different levels of morbidity or mortality.

RESULTS

The government has a great influence on the change in Rt value through prevention and control measures. The most important factors for personal and group prevention and control are the mobility index, testing, the closure of educational facilities, restrictions on large-scale gatherings, and commercial restrictions. The number of ICU beds and doctors in medical resources are also key factors. Basic sanitation facilities, such as the proportion of safe drinking water, also have an impact on the COVID-19 epidemic.

CONCLUSIONS

We described the current status of COVID-19 in European countries. Our findings demonstrated key factors in individual and group prevention measures.

Self-reported changes in cannabis vaping among US adolescents and young adults early in the COVID-19 pandemic

Cannabis vaping may increase susceptibility to COVID-19 infection and related outcomes; however, little is known about the impact of the pandemic on cannabis vaping among US young populations. This study examined self-reported changes in cannabis vaping since the pandemic and factors associated with changes. A national, cross-sectional survey was conducted among 4,351 US adolescents and young adults (13–24 years old) in May 2020. Of those, 1,553 participants who reported ever vaping cannabis were included in the analytic sample. Binary outcome was self-reported increase in cannabis vaping (more hours/times of vaping in a day) vs. no change/quitting/reducing/switching. Weighted logistic regression examined associations between independent variables (i.e., risk perceptions of vaping, cannabis dependence, and stress/anxiety) and the outcome, controlling for sociodemographic factors. Overall, 6.8% reported increasing cannabis vaping since the pandemic, 37.0% quitting or reducing vaping in general, and 42.3% no change. Participants were more likely to report increased cannabis vaping if they perceived “Vaping is safer than smoking cigarettes” (Adjusted Odds Ratio [AOR] = 3.66; 95%CI = 1.43–9.38), reported more dependence on cannabis vaping (AOR = 1.59; 95%CI = 1.11–2.27), and were female (AOR = 2.80; 95%CI = 1.23–6.36). Those perceiving “Vaping cannabis can cause lung injuries” were less likely to increase cannabis vaping (AOR = 0.37; 95%CI = 0.18–0.76). Findings indicate that adolescent and young adult ever-cannabis vapers were more likely to report decreasing vaping generally than increasing cannabis vaping and most did not change use during the early pandemic. Educational campaigns should address potential health risks of cannabis vaping and focus on lung health to reduce use among young people during and following the pandemic.

Turning over a new leaf: Vape shop closings, openings and transitions in six U.S. Metropolitan statistical areas

This study characterizes vape shop closings, openings, and changes in product mix in six U.S. metropolitan statistical areas with different tobacco and marijuana policies. With concern for higher rates of marijuana use among those who vape nicotine, the presence of marijuana-related terms in store names was also assessed. A census of stores that were classified online as vape shops/stores or vaporizer stores were telephoned in April-May 2018 (n = 739) and July-September 2019 (n = 919) to verify whether vape products and other tobacco products (OTP) were sold. We computed the percent of stores that closed, opened, and started/stopped selling OTP. Multilevel models tested whether these events varied by store type and by neighborhood demographics. Within 16 months, 11.5% of 739 stores had closed and 29.8% of 919 stores at follow-up had opened. Closings were more likely among vape-only than vape + OTP stores (AOR = 2.51, 95% CI = 1.47,4.29); vape-only stores were less likely to open (AOR = 0.46, 95% CI = 0.34,0.62). Regardless of store type, the odds of a store opening increased as the proportion of non-Hispanic/Latino White residents in the census tract increased (AOR = 1.47, 95% CI = 1.18,1.85). Overall, 2.0% of stores (vape-only and vape + OTP) had marijuana-related names at baseline and 3.5% at follow-up. The observed change (1.6% to 5.8%) was greatest in Oklahoma City, where the state legalized medical marijuana between baseline and follow-up. More stores were opening than closing in six U.S. metropolitan statistical areas before statewide sales restrictions on flavored tobacco and COVID-19. Uniform licensing is recommended to define vape shops and track their location and sales practices.

Perceived Susceptibility to and Seriousness of COVID-19: Associations of Risk Perceptions with Changes in Smoking Behavior

During the COVID-19 pandemic, studies have documented increased and decreased cigarette smoking among adults. Individual differences in the perceived susceptibility and seriousness of the virus, for people who smoke in general and for oneself personally, may relate to changes in smoking. Using the Health Belief Model (HBM) as a theoretical framework, we examined associations with self-reported increasing and decreasing smoking a lot during the COVID-19 stay-at-home period. Adults in 30 large U.S. cities who smoked cigarettes daily completed an online survey between 14 July and 30 November 2020. The analytic sample (N = 2768) was 54.0% male and 68.3% white with 23.7% reporting increasing and 11.3% decreasing smoking (6% reported both). Younger age, a diagnosis of COVID-19, and greater pandemic-related stress were associated with greater odds of both increased and decreased smoking. Increased smoking also was associated with heavier nicotine dependence, greater desire to quit, and greater perceived susceptibility and lower perceived seriousness of COVID-19 for people who smoke, while pandemic-related job-loss, lower nicotine dependence, and greater self-efficacy were associated with decreased smoking. Among respondents who had not contracted COVID-19 (n = 2418), correlates were similar with the addition of greater perceived personal susceptibility to COVID-19 associated with both increased and decreased smoking, while greater perceived personal seriousness of COVID-19 was associated with increased smoking. Findings for risk perceptions were largely in directions that contradict the HBM. Circumstances surrounding behavior change during the pandemic are complex and may be especially complex for nicotine addiction.

Longitudinal Tracking of Vape Shop Compliance With State Business Regulations Within Southern California Ethnic Neighborhoods During the COVID-19 Pandemic

The overall aim of this study is to examine vape shop business operations during COVID-19 among a cohort of 88 vape shops in the Greater Los Angeles area in Southern California, located in ethnically diverse communities. A total of six web- and/or phone-based assessments were conducted over a 12-week period (April 1, 2020-June 10, 2020), extending from the mandated closure of nonessential businesses (Stage 1; Assessments 1-3) to the reopening of nonessential sectors (Stage 2; Assessments 4-6), to evaluate business operations (open and closure statuses). The proportion of vape shops found to be noncompliant with the Governor's executive order (i.e., open) during Stage 1 gradually increased from 54 (61.4%) at Assessment 1 (week of April 1, 2020) to 58 (65.9%) at Assessment 3 (week of April 29, 2020). Moreover, vape shops located in Hispanic/Latino and Korean/Asian communities (vs. those in non-Hispanic White and African American communities) were more likely to stay open both during and after the shutdown at Assessments 1 and 6. More specifically, vape shops located in Hispanic/Latino communities were significantly more likely to offer walk-in service during Assessment 1 (during the shutdown), and vape shops in Hispanic/Latino and Korean/Asian were significantly more likely to offer walk-in service during Assessment 6 (after the re-opening). This study demonstrates high rates of noncompliance with shutdown orders among vape shops located in ethnic communities, thus suggesting higher contextual risk factors of COVID-19 exposure among certain ethnic communities.

Aerial Transmission of the SARS-CoV-2 Virus through Environmental E-Cigarette Aerosols: Implications for Public Policies

We discuss the implications of possible contagion of COVID-19 through e-cigarette aerosol (ECA) for prevention and mitigation strategies during the current pandemic. This is a relevant issue when millions of vapers (and smokers) must remain under indoor confinement and/or share public outdoor spaces with non-users. The fact that the respiratory flow associated with vaping is visible (as opposed to other respiratory activities) clearly delineates a safety distance of 1-2 m along the exhaled jet to prevent direct exposure. Vaping is a relatively infrequent and intermittent respiratory activity for which we infer a mean emission rate of 79.82 droplets per puff (6-200, standard deviation 74.66) comparable to mouth breathing, it adds into shared indoor spaces (home and restaurant scenarios) a 1% extra risk of indirect COVID-19 contagion with respect to a "control case" of existing unavoidable risk from continuous breathing. As a comparative reference, this added relative risk increases to 44-176% for speaking 6-24 min per hour and 260% for coughing every 2 min. Mechanical ventilation decreases absolute emission levels but keeps the same relative risks. As long as direct exposure to the visible exhaled jet is avoided, wearing of face masks effectively protects bystanders and keeps risk estimates very low. As a consequence, protection from possible COVID-19 contagion through vaping emissions does not require extra interventions besides the standard recommendations to the general population: keeping a social separation distance of 2 m and wearing of face masks.
