Clinical manifestations of EVALI in adolescents and the impact of e-cigarettes on the respiratory disease

In recent years there has been a significant increase in the popularity of electronic cigarettes among adolescents and young adults worldwide. E-cigarettes have reached the market without the extensive preclinical toxicology testing or long-term safety studies required for conventional therapeutics and medical devices. Their effectiveness as a smoking cessation intervention, their impact at the population level and whether they are less harmful than combustible tobacco products are highly controversial. Studies show measurable adverse biological effects on organ and cell health in humans, animals and in vitro. E-cigarette use also increases the risk of respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma. There is a serious risk of complications associated with e-cigarette use, such as EVALI (E-cigarette or Vaping Product Use-Associated Lung Injury) - serious lung damage associated with, especially for adolescents. This paper reviews the effects of e-cigarettes on respiratory health.

How is nicotine vaping product (e-cigarette) use monitored in primary care electronic health records in the United Kingdom? An exploratory analysis of Clinical Practice Research Datalink (CPRD)

BackgroundElectronic health records (EHRs) could identify long-term health effects of nicotine vaping. We characterised the extent to which vaping is recorded in primary care EHRs in the UK, on a population level.MethodsWe performed descriptive analysis of Clinical Practice Research Datalink (CPRD), primary care electronic health records of 25% of the UK population (~ 16 million patients). Patients aged ≥ 18 years whose vaping status was recorded using medical codes between 2006 and 2022 were identified. We reported the frequency of vaping codes; their distribution by patient age, gender, and ethnicity; trends in vaping recording over time (including interrupted time series analyses); and transitions in patient smoking status.ResultsSeven medical codes indicated current or former vaping, from 150,114 patients. When their vaping status was first recorded, mean patient age was 50.2 years (standard deviation: 15.0), 52.4% were female, and 82.1% were White. Of those recorded as currently vaping, almost all (98.9%) had records of their prior smoking status: 55.0% had been smoking, 38.3% had stopped smoking, 5.6% had never smoked. Of those who were smoking prior to being recorded as vaping, more than a year after the vaping record, over a third (34.2%) were still smoking, under a quarter (23.7%) quit smoking, 1.7% received a ‘never smoked’ status, and there was no smoking status for 40.4%. The ‘e-cigarette or vaping product use-associated lung injury’ (EVALI) outbreak was significantly associated with a declining trend in new records of current vaping between September 2019 and March 2020; and an immediate significant increase in new records of former vaping, followed by a declining trend.ConclusionsFew patients are being asked about vaping. Most who vape had smoked, and many quit smoking after starting vaping. To enable electronic health records to provide stronger evidence on health effects, we recommend improved completeness, accuracy and consistency.

Cannabis Vape Product Sales in California Following CDC's Initial Advisory About Lung Injuries.

Introduction: The 2019 outbreak of e-cigarette or vaping product use-associated lung injury (EVALI) is believed to have been caused by vitamin E acetate, an additive used in some cannabis vaporizer products. Previous studies have primarily focused on changes in sales of electronic nicotine delivery systems following the initial advisory issued by the Centers for Disease Control (CDC) on August 17, 2019. The present study is intended to examine variation by age groups in sales of regulated cannabis vape products in the state of California before, during, and after the outbreak. Methods: Weekly sales revenue of cannabis vape products (from January 1, 2018, to December 31, 2020) was obtained from a sample of recreational cannabis retailers licensed in California. An interrupted time series analysis, using AutoRegressive, Integrated, Moving Average methods, was employed to estimate changes in the sales and market share of cannabis vape products in the weeks following the CDC advisory. Results: The total volume of regulated cannabis vape product sales increased substantially over the 3-year study period (2018-2020). Sales and market share of cannabis vape products, however, declined in both young and older adults immediately following the advisory, rebounding to pre-EVALI levels only for the young adults. For sales, the potential EVALI effect following the CDC's advisory equates to an 8.0% and 2.2% decline below expected levels in the older and young adults, respectively. Conclusions: The differential age effect on sales may reflect concerns regarding health effects of cannabis vaping products and greater awareness of the outbreak among older adults. Findings highlight the importance of informing consumers about health risks associated with using cannabis vape products acquired from regulated versus illicit sources.

Vaping lung damage (review)

The review presents data from meta-analyses and original studies on the study of the vapers disease electronic cigarette or vaping product use-associated lung injury (EVALI) a new nosological form in patients with acute and subacute respiratory diseases caused by the consumption of electronic nicotine delivery vehicles, or vaping. The number of users are growing in around the world, especially among young people. According to a 2022 meta-analysis, the global prevalence of vaping use was 23%, including 16% in women and 22% in men. Prevalence of electronic nicotine delivery systems among cigarette smokers reached 43%, while on different continents, except for Asia, during the life it was approximately the same: in America 24%, Europe 26%, Asia 16%, Oceania 25%. Vaping rates among children aged 15 to 17 are almost four times (21.3%) higher than those aged 1214 (5.4%). Two-thirds (66.1%) of children aged 12 to 17 using electronic nicotine delivery devices were also smokers, while they started with vapes. Nicotine cartridges used by 89.3% of teen vapers aged 15 to 19 years. Vaping lung diseases have been reported since invention e-cigarettes, but the number of cases increased sharply at the end of September 2019, and by February In 2020, the number of hospitalized patients in the United States reached 2807, with 68 confirmed deaths. Most of the cases are male adolescents and men aged 1334 years. The review discusses the etiology, clinical picture, imaging findings, pathological EVALI features. When examining patients with EVALI, computed tomography revealed images characteristic of acute lung injury and pneumonia, as well as those resembling non-fibrous hypersensitivity pneumonitis, acute eosinophilic pneumonia. The article discusses the main differences between these diseases and the computed tomography picture of COVID-19. Before EVALI, vaping was associated with a wide range of pulmonary manifestations, including lipoid pneumonia, acute respiratory distress syndrome and diffuse alveolar hemorrhage. Although the overall prevalence of EVALI has declined sharply compared to with a peak in September 2019, other chemicals may appear that cause various pulmonary diseases associated with vaping. EVALI is a new nosological form in patients with acute and subacute respiratory diseases caused by lung damage due to the use of electronic means delivery of nicotine. The appearance of radiographic images in EVALI is diverse: from bilateral opacities in the lungs to reveal centrilobular nodules resembling non-fibrous hypersensitivity pneumonitis. When interpreting acute lung injury in young people, the possibility of EVALI should be considered.

Cardiopulmonary Impact of Electronic Cigarettes and Vaping Products: A Scientific Statement From the American Heart Association.

Vaping and electronic cigarette (e-cigarette) use have grown exponentially in the past decade, particularly among youth and young adults. Cigarette smoking is a risk factor for both cardiovascular and pulmonary disease. Because of their more limited ingredients and the absence of combustion, e-cigarettes and vaping products are often touted as safer alternative and potential tobacco-cessation products. The outbreak of e-cigarette or vaping product use-associated lung injury in the United States in 2019, which led to >2800 hospitalizations, highlighted the risks of e-cigarettes and vaping products. Currently, all e-cigarettes are regulated as tobacco products and thus do not undergo the premarket animal and human safety studies required of a drug product or medical device. Because youth prevalence of e-cigarette and vaping product use was as high as 27.5% in high school students in 2019 in the United States, it is critical to assess the short-term and long-term health effects of these products, as well as the development of interventional and public health efforts to reduce youth use. The objectives of this scientific statement are (1) to describe and discuss e-cigarettes and vaping products use patterns among youth and adults; (2) to identify harmful and potentially harmful constituents in vaping aerosols; (3) to critically assess the molecular, animal, and clinical evidence on the acute and chronic cardiovascular and pulmonary risks of e-cigarette and vaping products use; (4) to describe the current evidence of e-cigarettes and vaping products as potential tobacco-cessation products; and (5) to summarize current public health and regulatory efforts of e-cigarettes and vaping products. It is timely, therefore, to review the short-term and especially the long-term implications of e-cigarettes and vaping products on cardiopulmonary health. Early molecular and clinical evidence suggests various acute physiological effects from electronic nicotine delivery systems, particularly those containing nicotine. Additional clinical and animal-exposure model research is critically needed as the use of these products continues to grow.

Is nicotine vaporization a better alternative to traditional cigarette smoking? E-cigarettes harmful effects summary and the management of EVALI based on the latest literature

Introduction: Electronic cigarettes are battery-powered devices that allow users to inhale vapor produced by heating a liquid (e-liquid) containing nicotine and other substances. The first such devices were introduced in China in 2003, and subsequently approved for use in the European Union in 2006 and the United States in 2007. The number of e-cigarette users is constantly growing, with the largest increases observed in the 18-24 age group. Various modifications led to the emergence of a new disease entity in 2019 called EVALI (e-cigarette or vaping product use-associated lung injury).
 Aim of the study: To summarize the current state of knowledge about harmful substances contained in e-cigarettes and to systematize the latest methods of management in cases of suspected EVALI.
 Methods and materials: A literature review was conducted using PubMed, Google Scholar, and ScienceDirect, including publications from the last 8 years, using the following keywords: "E-cigarette," "Electronic cigarette," "EVALI," "THC," "Vitamin E."
 Results: Electronic cigarettes contain a number of substances harmful to health. E-cigarettes have not been approved as nicotine replacement therapy. The presence of vitamin E breakdown products in the respiratory tract of EVALI patients has been confirmed. Vitamin E was primarily used to increase the volume of e-liquids containing THC.
 Conclusions: Electronic cigarettes should not be used due to the numerous harmful substances they contain. When using e-cigarettes, both the devices and the e-liquids should be purchased from reputable sellers approved in the respective country. EVALI is a potentially fatal disease, and prompt diagnosis facilitates treatment

A Large Lung Abscess in an Electronic Cigarette User: To Drain or Not to Drain

A lung abscess is a walled necrotizing infection involving the lung parenchyma, characterized by a cavitary lesion filled with fluid. It is usually caused by microbial infection with aspiration of oropharyngeal contents being the most common mechanism for primary lung abscesses. Secondary lung abscesses occur in the presence of predisposing lung conditions like bronchial obstruction, vascular or septic emboli or impaired host defenses. Lung abscesses caused by electronic cigarette use have gained relevance in the recent years since the outbreak of EVALI, that is, e-cigarette or vaping product use-associated lung injury, in 2019. First-line therapy involves prompt initiation of antibiotics given their success rate in the treatment of lung abscess in the current potent antibiotic era. Percutaneous aspiration and catheter drainage is considered a second line approach due to concerns for potential complications including catheter blockage necessitating repeat procedures, pneumothorax, hemothorax, hemoptysis, need for surgical intervention, infection of pleural space and bronchopleural fistula. We describe a case of a 21-year-old female with a history of electronic cigarette use presenting with a large left upper lobe lung abscess (14.5 x 8.5 x 13.3 cm) treated successfully with broad-spectrum antibiotics alone resulting in clinical and radiologic improvement.

US researchers call for FDA action to avoid another EVALI outbreak.

Researchers are calling for tighter US Food & Drug Administration (FDA) regulation of vaping products to avoid another outbreak of e-cigarette or vaping product use-associated lung injury (EVALI). EVALI hospitalised thousands of Americans starting in 2019, most of them teenagers or young adults, leaving many survivors with damaged lungs and persisting pulmonary dysfunction.

Bronchoalveolar Lavage (BAL) and Pathologic Assessment of Electronic Cigarette or Vaping Product Use-associated Lung Injury (EVALI): The EVALI-BAL Study, A Multicenter Cohort.

E-cigarette or vaping-use related acute lung injury (EVALI) is a spectrum of radiographic and histologic patterns consistent with acute to subacute lung injury. However, limited data exist characterizing bronchoalveolar lavage (BAL) findings. The goal of this study is to further define the pathologic findings from BAL and biopsy samples of subjects with EVALI across 7 institutions. A multicentered registry of patients admitted with EVALI who underwent flexible bronchoscopy with BAL+/-transbronchial biopsy from July 2019 to April 2021 was compiled for retrospective evaluation from 7 academic institutions throughout the United States. Radiographic and cytopathologic findings and frequencies were correlated with the substance vaped. Data from 21 subjects (42.9% women) who were predominantly White (76.2%) with a median age of 25 years (range, 16 to 68) with EVALI were included in this study. Sixteen patients (76.2%) reported use of tetrahydrocannabinol; the remainder used nicotine. BAL was performed in 19 of the 21 subjects, and transbronchial lung biopsy was performed in 7 subjects. BAL findings revealed neutrophilic predominance (median, 59.5%, range, 3.1 to 98) in most cases. Ten BAL samples demonstrated pulmonary eosinophilia ranging from 0.2% to 49.1% with one subject suggesting a diagnosis of acute eosinophilic pneumonia associated with the use of e-cigarettes. Lipid-laden macrophages were noted in 10 of 15 reports (66.7%). Transbronchial biopsy most frequently demonstrated patterns of organizing pneumonia (57.1%). EVALI-associated BAL findings typically demonstrate a spectrum of nonspecific inflammatory changes, including neutrophilia, lipid-laden macrophages, and in some cases eosinophilia.

The E-cigarette or Vaping Product Use-Associated Lung Injury Epidemic: Pathogenesis, Management, and Future Directions: An Official American Thoracic Society Workshop Report.

E-cigarette or vaping product use-associated lung injury (EVALI) is a severe pulmonary illness associated with the use of e-cigarettes or vaping products that was officially identified and named in 2019. This American Thoracic Society workshop was convened in 2021 to identify and prioritize research and regulatory needs to adequately respond to the EVALI outbreak and to prevent similar instances of disease associated with e-cigarette or vaping product use. An interdisciplinary group of 26 experts in adult and pediatric clinical care, public health, regulatory oversight, and toxicology were convened for the workshop. Four major topics were examined: 1) the public health and regulatory response to EVALI; 2) EVALI clinical care; 3) mechanisms contributing to EVALI; and 4) needed actions to address the health effects of EVALI. Oral presentations and group discussion were the primary modes used to identify top priorities for addressing EVALI. Initiatives including a national EVALI case registry and biorepository, integrated electronic medical record coding system, U.S. Food and Drug Administration regulation and enforcement of nicotine e-cigarette standards, regulatory authority over nontobacco-derived e-cigarettes, training in evaluating exogenous exposures, prospective clinical studies, standardized clinical follow-up assessments, ability to more readily study effects of cannabinoid e-cigarettes, and research to identify biomarkers of exposure and disease were identified as critical needs. These initiatives will require substantial federal investment as well as changes to regulatory policy. Overall, the workshop identified the need to address the root causes of EVALI to prevent future outbreaks. An integrated approach from multiple perspectives is required, including public health; clinical, basic, and translational research; regulators; and users of e-cigarettes. Improving the public health response to reduce the risk of another substantial disease-inducing event depends on coordinated actions to better understand the inhalational toxicity of these products, informing the public of the risks, anddeveloping and enforcing regulatory standards for all e-cigarettes.

Ecigarette or Vaping Product Use Associated Lung Injury (EVALI) Reports to NPDS Implicated New Marijuana Substances

Context: Beginning Aug-2019, the Centers for Disease Control and Prevention (CDC) initiated investigation of e-cigarette or Vaping Product Use-Associated Lung Injury (EVALI). We examined all National Poison Data System (NPDS) EVALI cases through 31-Mar-2020 for substances, treatments, clinical effects, and medical outcome. We also examined all NPDS eCig exposures for earlier reports of EVALI. Methods: We extracted all exposures coded to EVALI product code 7322608 (E-Cigarette Associated Pulmonary Illness) and all single substance exposures to any of 6 NPDS eCig generic codes (GCs). We examined substance, patient characteristics, and exposure details on the severity of EVALI via multivariate analyses. We developed an EVALI clinical score (ECS) based on the EVALI clinical effects (CEs) and treatments weighted by the % of cases for each finding. We used ECS to search for EVALI candidate cases from 2001 to 31-Mar-2020. Descriptive statistics and change over time via linear and quadratic regression, and multivariate analyses were via (SAS JMP, 12.0.1). Discussion: Through 31-Mar-2020, PCs reported 822 EVALI cases. The EVALI profile over time 15-Aug - 12-Sep-2019 for 196 cases was described by an exponential increase with a doubling time [95% CI] of 8.31 [8.24, 8.37] days. Age: median [min, max] was 22 [1, 77] years, Male: 64.9%, Chronic 50.3%. Medical Outcomes included Death 1.95%, Major 17.9%, and Moderate 57.1%. Multivariate analysis of the first 107 EVALI cases as of 14-Sep-2019 implicated Marijuana Products (p=0.0007). Similar analyses of all 822 cases confirmed Marijuana (p<0.00001), Chronicity (p=0.00031), and Age (p=0.0152) contributing to CE score. Of the 23,252 eCig exposures (23,463 - 211 EVALI cases), 133 (0.567%) had an ECS > median and 370 (1.57%) scored > 25%tile of EVALI cases (EVALI-25+). The time course of these 370 eCig cases showed a distinct increase (inflection) ~16- Aug-2019. Conclusions: The first 107 NPDS EVALI case scores were related to marijuana product exposure. This was confirmed via similar analyses for all 822 cases. The numbers of EVALI-25+ cases show a distinct increase in Aug-2019, suggesting EVALI was a newly emerging phenomenon. Our analysis should encourage public health agencies to utilize NPDS, especially in data collection.

Cholesterol enhances the negative impact of vaping additives on lung surfactant model systems.

Aims: Vaping has given rise to e-cigaretteor vaping productuse-associatedlung injury. Model lung surfactant films were used to assess the impact of vape additives (vitamin E, vitamin Eacetate, tetrahydrocannabinol, cannabidiol). This work builds upon our previous findings, by incorporating cholesterol, to understand the interplay between the additives and the sterol in surfactant function. Materials & methods: Compression-expansion cycles of lipid monofilm at the air-water interface and Brewster angle microscopy allowed elucidating the effects of vape additives. Results & conclusion: Vape additives at 5mol% inhibited proper lipid packing and reduced film stability. Cholesterol enhanced the additive effects, resulting in significantly destabilized films and altered domains. The observed impact could signify dysfunctional lung surfactant and impaired lung function.

Vaping additives cannabinoid oil and vitamin E acetate adhere to and damage the human airway epithelium.

E-cigarette, or vaping product use-associated lung injury (EVALI), is a severe respiratory disorder that caused a sudden outbreak of hospitalized young people in 2019. Using cannabis oil containing vaping products, including vitamin E acetate contaminants, was found to be strongly associated with EVALI. However, the underlying tissue impacts of the condition are still largely unknown. Here, we focused on the vehicle cannabinoid oil (CBD oil) and contaminant vitamin E acetate (VEA) effects on airway epithelial cells. Primary human bronchial epithelial (HBE) cultures were exposed to e-liquid aerosols that contained CBD oil and VEA in combination or the common e-liquid components PG/VG with and without nicotine. Cell viability analysis indicated dramatically increased cell death counts after 3 days of CBD exposure, and this effect was even higher after CBD + VEA exposure. Microscopic examination of the cultures revealed cannabinoid and VEA depositions on the epithelial surfaces and cannabinoid accumulation in exposed cells, followed by cell death. These observations were supported by proteomic analysis of the cell secretions that exhibited increases in known markers of airway epithelial toxicity, such as xenobiotic enzymes, factors related to oxidative stress response, and cell death indicators. Overall, our study provides insights into the association between cannabinoid oil and vitamin E acetate vaping and lung injury. Collectively, our results suggest that the adherent accumulation of CBD oil on airway surfaces and the cellular uptake of both CBD oil- and VEA-containing condensates cause elevated metabolic stress, leading to increased cell death rates in human airway epithelial cultures.

E-cigarette or vaping product use-associated lung injury: A review of clinico-radio-pathological characteristics.

Aggressive, albeit false marketing of electronic nicotine delivery systems (ENDS) or vaping devices as safer alternatives to cigarette smoking, combined with lack of regulations, has led to its mass adoption, especially among youth. A sudden increase in acute lung injuries was noted in 2019 which was linked to ENDS. It was termed by the Centers for Disease Control and Prevention (CDC) as electronic cigarette or vaping product use-associated lung injury (EVALI). Analysis of bronchoalveolar lavage fluid samples linked EVALI to vitamin E acetate (VEA), which is used as a diluting agent for marijuana oils. Patients with EVALI present with a combination of non-specific respiratory, gastrointestinal, and systemic symptoms. Laboratory results may show elevated inflammatory biomarkers. EVALI is a diagnosis of exclusion and must meet the following criteria: i) history of vaping within last 90 days, ii) abnormal chest imaging, iii) negative evaluation for infection, and iv) no other plausible diagnosis. A spectrum of computed tomography (CT) chest findings has been reported in EVALI, ranging from diffuse alveolar damage to organizing pneumonia, characterized by bilateral ground-glass opacities, consolidation, and septal thickening. A similar spectrum is seen on histopathology, characterized by lipid-laden alveolar macrophages, with varying degrees of infiltrative inflammatory cells and fibrin deposition. Early and accurate identification of the EVALI pattern can help optimize patient care. For example, in diffuse alveolar damage (DAD), a lower threshold for ventilation support and corticosteroid may improve outcomes. Here, we review the etiopathogenesis, clinical management, histopathology, and imaging features of EVALI.

The Knowledge and Attitude about New Generation Tobacco Products among Physicians.

Health hazards of e-cigarettes including "e-cigarette or vaping product use-associated lung injury" are better understood today. Just as e-cigarettes, heated tobacco products release toxic emissions. We aimed to determine the knowledge and attitude about new generation tobacco products among physicians who were the members of an organization for health care professionals, the majority of whom are pulmonologists. In this cross-sectional study, a self-administered online questionnaire-based survey was conducted among the physicians from April to October 2019. The survey included questions about demographics (gender, age, graduation date from medical institution, and academic title), their smoking status, their knowledge and attitudes toward new generation tobacco products, and additionally about whether new generation tobacco products can be used to aid in smoking cessation. Among the 506 members who responded to the survey, 56.7 % were female; the mean age was 42.4 ± 10.9 years (20-74). About 74.5% were pulmonologists, 5.5% were thoracic surgeons, and 20% were other physicians. Among the responders, the frequency of those who have not heard of new generation tobacco products before was determined as 9.5%, 24.5%, and 41.3%. At least 58.9% of participants lacked the knowledge necessary to discuss these products with their patients and the rate reached 76.7% for the heated tobacco product. To the question of whether new generation tobacco products can be used in smoking cessation, 68.4% responded "I never agree that they can be used." Non-current smokers (P = .003), elders (P = .001), those who had training on smoking cessation assistance (P = .001), and those who had experience in smoking cessation assistance (P = .009) were significantly more prevalent in the group who answered: "I never agree that they can be used." Physicians must become considerably more knowledgeable about the new generation tobacco products and hazards. Otherwise, these new tobacco products may pose new threats to national and global tobacco control efforts.

The inverse association of state cannabis vaping prevalence with the e-cigarette or vaping product-use associated lung injury.

The e-cigarette or vaping product-use-associated lung injury (EVALI) epidemic was primarily associated with the use of e-cigarettes containing tetrahydrocannabinol (THC)- the principal psychoactive substance in cannabis, and vitamin-E-acetate- an additive sometimes used in informally sourced THC-containing e-liquids. EVALI case burden varied across states, but it is unclear whether this was associated with state-level cannabis vaping prevalence. We, therefore, used linear regression models to assess the cross-sectional association between state-level cannabis vaping prevalence (obtained from the 2019 behavioral Risk Factor Surveillance System) and EVALI case burden (obtained from the Centers for Disease Control and Prevention) adjusted for state cannabis policies. Cannabis vaping prevalence ranged from 1.14%(95%CI, 0.61%-2.12%) in Wyoming to 3.11%(95%CI, 2.16%-4.44%) in New Hampshire. EVALI cases per million population ranged from 1.90(0.38-3.42) in Oklahoma to 59.10(19.70-96.53) in North Dakota. There was no significant positive association but an inverse association between state cannabis vaping prevalence and EVALI case burden (Coefficient, -18.6; 95%CI, -37.5-0.4; p-value, 0.05). Thus, state-level cannabis vaping prevalence was not positively associated with EVALI prevalence, suggesting that there may not be a simple direct link between state cannabis vaping prevalence and EVALI cases, but rather the relationship is likely more nuanced and possibly reflective of access to informal sources of THC-containing e-cigarettes.

Analysis of state portrayals of the risks of e-cigarette use and the cause of the EVALI outbreak

IntroductionIn August 2019, an outbreak of “e-cigarette or vaping product use-associated lung injury” (EVALI) prompted many states and health organizations to warn against the use of electronic cigarettes, or e-cigarettes, due to the presumed link between e-cigarette use and the illness. However, it was later shown that vitamin E acetate, a component of some illicit vaporizable THC products, was the causative agent in this outbreak.MethodsWe conducted a series of cross-sectional surveys of the websites of all state departments of health to determine how they communicated the risk of e-cigarette use during and after the EVALI outbreak. We then paired this analysis with data from the 2016 through 2020 Behavioral Risk Factor Surveillance System to measure changes in cigarette and e-cigarette use.ResultsWebsite data from 24 states was available for analysis at all three time points of interest, and BRFSS data was only available for 8 of these states. We found that by January 2020, a majority of the states surveyed did not list vaporizable THC use as a cause of EVALI; however, differences in state messaging did not appear to be associated with changes in e-cigarette and cigarette use.ConclusionsGiven the number of states that did not appear to update their messaging regarding the cause of EVALI, we believe that states should re-evaluate this messaging to accurately communicate the risks of e-cigarette use.

The Complexity in the Diagnosis and Treatment of Symptoms in Electronic Cigarette Users during the COVID-19 Pandemic

The issue with the overlapping clinical symptoms from an electronic cigarette (e-cigarette) or vaping product use-associated lung injury (EVALI) and coronavirus disease 2019 (COVID-19) sometimes leads to incorrect diagnosis and, consequently, wrong treatment regimen. The purpose of this review is to study the burden of vaping-associated health consequences on the diagnosis and treatment of COVID-19 in young adults and adolescents with a misconception of e-cigarettes as a safer alternative to smoking. The online reference databases, including PubMed, Google Scholar, Web of Science, Medline, and Centers for Disease Control and Prevention (CDC), were used in the literature search, as we analyzed the complexity of timely diagnosis and treatment in the current COVID-19 era with the use of e-cigarettes. This study briefly describes the dysbiosis of the oral microbiome in e-cigarette users that could potentially aggravate the COVID-19 symptoms and lead to the complexity of timely diagnosis and treatment. Additionally, the patient case reports with a history of vaping and symptoms similar to COVID-19 disease are reviewed.
