Potential link between vaping and hypothyroidism: A case report

Background: Vaping has gained popularity as an alternative to traditional smoking, but its potential health effects, particularly on endocrine function, remain under-explored. This case report highlights a possible association between vaping and the development of subclinical hypothyroidism in a young adult female. Case Presentation: A 25-year-old female with a history of vaping for 30 minutes daily over the course of one year presented with symptoms of fatigue, weight gain, and dry skin. Initial thyroid function tests showed elevated TSH (5.08 uIU/mL), reduced T3 (64 ng/dL), and T4 (4.8 ug/dL), consistent with subclinical hypothyroidism. After discontinuing or reducing vaping, repeat thyroid function tests revealed an improvement in thyroid hormone levels (TSH: 4.69 uIU/mL, T3: 136.4 ng/dL, T4: 5.77 ug/dL) and symptom relief. The use of a vaping device with a lithium-ion battery raised concerns about possible lithium exposure, a known factor in thyroid dysfunction. Conclusion: This case suggests a potential reversible association between vaping and subclinical hypothyroidism, possibly exacerbated by lithium toxicity from battery leakage. Further research is necessary to understand the mechanisms behind vaping-related thyroid dysfunction and the potential role of lithium in this process.

Chemical Composition of Aerosols from the E-Cigarette Vaping of Natural and Synthetic Cannabinoids.

Vaping cannabinoids in electronic (e)-cigarette devices is rapidly increasing in popularity, particularly among adolescents, although the chemistry affecting the composition of the vape aerosol is not well understood. This work investigates the formation of aerosol mass, bioactive hydroxyquinones, and harmful or potentially harmful carbonyls from the e-cigarette vaping of natural and synthetic cannabinoids e-liquids in propylene glycol and vegetable glycerin (PG/VG) solvent at a 50 mg/mL concentration in a commercial fourth-generation vaping device. The following cannabinoids were studied: cannabidiol (CBD), 8,9-dihydrocannabidiol (H2CBD), 1,2,8,9-tetrahydrocannabidiol (H4CBD), cannabigerol (CBG), and cannabidiolic acid (CBDA). Quantification of analytes was performed using liquid chromatography coupled to accurate mass spectrometry. The addition of cannabinoids significantly increased aerosol and carbonyl formation compared with the PG/VG solvent alone. All cannabinoids in the study formed hydroxyquinones during vaping (up to ∼1% mass conversion) except for CBDA, which primarily decarboxylated to CBD. Hydroxyquinone formation increased and carbonyl formation decreased, with a decreasing number of double bonds among CBD and its synthetic analogues (H2CBD and H4CBD). During the vaping process, ∼3-6% of the cannabinoid mass can be observed as carbonyls under the study conditions. Oxidation of the terpene moiety on the cannabinoids is proposed as a major contributor to carbonyl formation. CBD produced significantly higher concentrations of formaldehyde, acetaldehyde, acrolein, diacetyl, and methylglyoxal compared with the other cannabinoid samples. CBG produced significantly higher levels of acetone, methacrolein, and methylglyoxal. Conversion of CBD to tetrahydrocannabinol (THC) was not observed under the study conditions. The chemical mechanism basis for these observations is discussed. Compared with other modalities of use for CBD and other cannabinoids, vaping has the potential to adversely impact human health by producing harmful products during the heated aerosolization process.

Marketing for Sensa: A novel "zero nicotine vapor product" from a major tobacco company.

On July 1, 2024, RJ Reynolds Vapor Company (RJRVC) introduced Sensa, the first disposable "zero nicotine vapor product" from a major tobacco company. Sensa sold more than 100,000 units as of September 10, 2024 and has been marketed through several channels. Direct-mail and magazine ads appeal to consumers' senses (e.g., "awaken your senses") and showcase Sensa's six flavor options: Berry Fusion, Berry Watermelon Fusion, Blueberry Frost, Mint Frost, Passionfruit Frost, and Watermelon Frost. Our chemical characterization of all Sensa flavors (except Berry Watermelon Fusion) found neotame (a potent artificial sweetener) and WS-23 (a synthetic coolant) in all samples, while all "Frost" flavors tested contained another synthetic coolant, WS-3. Although RJRVC states that Sensa is for "adult tobacco and vapor consumers," Sensa's resemblance to popular disposable vaping devices and youth-appealing flavors raise concerns about Sensa's appeal to young people, and limited regulations for "zero nicotine" products introduce uncertainty about product safety.

Perceptions and Cultural Practices of Vaping Among Lesbian, Bisexual, and Queer Women in Australia

Abstract Background The rising prevalence of vaping poses new challenges and opportunities for health policy and public health interventions. Given that, historically, smoking has been more prevalent among lesbian, bisexual, and queer (LBQ) women than other women, this study explores LBQ women’s perceptions and experiences of vaping. Methods Sixty LBQ women and some non-binary people (aged 18–72) participated in in-depth qualitative interviews between May and July 2023, providing insights into the emerging prevalence and nature of vaping within LBQ women’s communities. Thematic analysis techniques were employed to identify key themes, including (1) risk perceptions and social stigma, (2) gendered perceptions of vaping, and (3) experiences of vaping-related harms. Results Results highlight gendered perceptions of vaping among LBQ women, with participants describing vaping as a feminine practice, influenced by flavour choices and the visual aesthetics of vape devices. Despite perceiving vaping as more socially acceptable than smoking, some participants expressed a sense of embarrassment about vaping, while others reported substantial challenges and health concerns. Conclusion Concerns about vaping-related harms, addiction, and the evolving social dynamics of vaping contribute to LBQ women’s engagement with this emerging practice. Understanding these dynamics is crucial for developing targeted harm reduction strategies and support services tailored to LBQ women’s unique needs in the evolving landscape of vaping. Policy Implications Health and social policy may require specific responses to address higher rates of vaping among LGBTQ populations, including LBQ women.

“I’m committed, not addicted.”: College students’ identity and communication about vaping

Objective Vaping is a relatively new phenomenon, and trends in social vaping behaviors are developing. The current study describes and explains how communication surrounding vaping shapes different aspects of a college student’s identity. Participants Twenty-seven male and female college students at a large Midwestern university were recruited to participate in five focus groups. Methods Focus group findings were interpreted through the lens of the communication theory of identity. Results College students’ communication of identity was manifest in the personalization of vaping devices, selling vaping devices as a relational activity, the social aspects of vaping addiction, the facetious language surrounding vaping, and perceptions of vaping tricks as “cringe.” Conclusions The findings revealed narrow perceptions of acceptable identities for users of vaping devices. Participants avoided labels of “being addicted” and leveraged discursive strategies such as humor, facetious language, othering, and re-framing behavior to fit a desirable identity.

Patterns and perceptions of vaping among adults living in social housing: a representative survey in Great Britain, 2023

BackgroundVaping products are effective for helping people to stop smoking and may therefore offer a potential means to reduce high rates of smoking in socioeconomically disadvantaged groups. This study aimed to examine current patterns and perceptions of vaping among people living in social housing in Great Britain compared with those living in other housing types.MethodsData were from the Smoking Toolkit Study; a nationally-representative survey conducted in 2023 (n = 23,245). Logistic regression tested cross-sectional associations between living in social (vs. other) housing and current vaping among adults; vaping frequency, device type, nicotine concentration, and source of purchase among current vapers; use of vaping products as a smoking cessation aid among past-year smokers who tried to quit; and harm perceptions of vaping products relative to cigarettes among current smokers.ResultsCurrent vaping prevalence was twice as high among adults living in social housing (19.4%) compared with those in other housing types (10.4%; OR = 2.07, 95%CI = 1.84–2.33). This was partly explained by differences in sociodemographic characteristics and smoking status; after adjustment, the odds of being a current vaper were 33% higher (ORadj=1.33, 95%CI = 1.14–1.54). Among vapers, there were no notable differences by housing tenure in vaping frequency, main device type used, usual nicotine concentration, usual source of purchase, or use as a smoking cessation aid. However, current smokers living in social housing were more likely to think vaping is more harmful than cigarettes (31.6% vs. 21.8%; ORadj=1.61, 95%CI = 1.30–1.99).ConclusionsIn Great Britain, adults who live in social housing are more likely to vape than those who live in other housing types, even after accounting for their younger age and higher smoking rates. However, misperceptions about the relative harms of vaping products and tobacco are common among smokers living in social housing. Interventions addressing these misperceptions could help encourage more people living in social housing to switch from smoking to vaping and reduce smoking-related health inequalities.Pre-registrationThe study protocol and analysis plan were pre-registered on Open Science Framework (https://osf.io/n3mvs/).

Effects of Very Low Nicotine Content Cigarettes and Nicotine Vaping Device Characteristics on Choices to Smoke, Vape, or Abstain in Early Young Adults.

A national nicotine reduction policy could reduce the public health toll of smoking. However, reducing nicotine in cigarettes may lead to changes in the use of other tobacco products such as nicotine vaping devices, particularly among young people. Product use outcomes may depend on characteristics of available nicotine vaping devices. We aimed to determine the impact of cigarette nicotine content, vaping device nicotine concentration, and vaping device flavors on choices to smoke, vape, or abstain. Early young adults (ages 18-20 inclusive, N=80) who reported smoking daily and vaping nicotine at least twice in their lifetime participated in a laboratory study. Participants received either Very Low Nicotine Content (VLNC; 0.4mg nicotine/g of tobacco) or Normal Nicotine Content (NNC; 15.8mg/g) cigarettes. First, participants chose between their assigned cigarette or abstaining. Subsequently, participants chose between 2 cigarette puffs, 2 vape puffs, or abstaining. Vaping device nicotine concentration (3mg vs. 18mg/ml) and flavor (tobacco vs. non-tobacco) were manipulated within-subjects. When only cigarettes were available, there were no differences between the VLNC and NNC groups on cigarette choices. When the nicotine vaping device was concurrently available, the VLNC group made fewer choices to smoke than the NNC group. Non-tobacco flavors and lower vaping device nicotine concentration were associated with fewer choices to smoke. Nicotine vaping device availability reduced choices to smoke VLNC cigarettes, and vaping devices with lower nicotine and non-tobacco flavors led to the fewest choices to smoke. Regulators should consider that the availability and characteristics of alternative tobacco products can moderate the product standard's impact. The U.S. Food and Drug Administration may enact a reduced nicotine product standard that would affect all commercially-available cigarettes. One important population affected by this policy would be early young adults who smoke. We aimed to determine the impact of cigarette nicotine content, vaping device nicotine concentration, and vaping device flavors on choices to smoke, vape, or abstain. Lower nicotine in cigarettes, along with non-tobacco flavors and lower nicotine concentration in the vaping device, were associated with the fewest choices to smoke. Regulators should consider that the availability and characteristics of alternative tobacco products can moderate the product standard's impact.

A Systematic Literature Review on the Composition, Health Impacts, and Regulatory Dynamics of Vaping.

This comprehensive review deals with the multifaceted aspects of electronic cigarettes (e-cigarettes), examining their composition, health implications, regulatory challenges, and market dynamics. E-cigarettes, also known as vaping devices, function by warming a solution of liquid containing flavors, nicotine, and various other compounds to produce an aerosol for users to inhale. This review underscores the evolution and widespread adoption of e-cigarettes since their introduction in 2003, highlighting their appeal as alternatives to traditional tobacco smoking. The essential parts of e-cigarettes are the battery, heating element, e-liquid (or e-juice), and mouthpiece. Propylene glycoland vegetable glycerinare common ingredients in e-liquids, along with nicotine and other flavors. Concerns over the health impacts of e-cigarettes have grown, particularly in light of incidents like the e-cigarette or vaping-associated lung injuryoutbreak in 2019 linked to vaping-associated lung injuries. Evidence suggests that while e-cigarettes may pose fewer risks than conventional cigarettes, they are not without health consequences, including potential respiratory and cardiovascular effects. Regulatory efforts worldwide have struggled to keep pace with the rapid evolution of e-cigarettes, exacerbated by their diverse flavors and marketing strategies that appeal to youth. The review discusses global regulatory responses, including bans and restrictions, to curb youth uptake and address public health concerns. Furthermore, the rise of a black market for e-cigarettes poses additional challenges to effective regulation and tobacco control efforts. In conclusion, while e-cigarettes offer potential harm reduction benefits for adult smokers seeking alternatives to traditional tobacco products, their widespread availability and evolving landscape necessitate vigilant regulatory oversight to protect public health, especially among youth. Future research should continue to explore the long-term health impacts and efficacy of e-cigarettes as smoking elimination aids, informing evidence-based policies and interventions.

Protonitazene detection in two cases of opioid toxicity following the use of tetrahydrocannabinol vape products in Australia

Introduction Protonitazene is an opioid belonging to the 2-benzylbenzimidazole structural class. We describe two cases of opioid toxicity involving the reported inhalation of a delta-9-tetrahydrocannabinol vape product in which protonitazene was detected. Case reports Case 1 was a young male found unconscious after the reported use of a delta-9-tetrahydrocannabinol vape. He suffered two subsequent apnoeic episodes requiring bag-valve-mask ventilation before eventual recovery. Only protonitazene was detected in blood at a concentration of 0.74 µg/L. Case 2 was a young male who died shortly after being found unresponsive. The postmortem femoral blood concentrations of protonitazene and delta-9-tetrahydrocannabinol were 0.33 µg/L and 2 µg/L, respectively. Analysis of a pod vaping device found in the decedent’s hand and a separate e-liquid bottle labelled as delta-9-tetrahydrocannabinol showed a mixture of protonitazene and delta-9-tetrahydrocannabinol. Discussion The opioid effects of protonitazene are mediated through β-arrestin2 and mu opioid receptor signalling pathways. Benzimidazole opioids are lipophilic and, when mixed with a suitable solvent, can be used in a vape device. It is anticipated that naloxone would have provided effective reversal of toxicity in our cases. Conclusions Novel routes of opioid administration, like vaping, may appear relatively innocuous in comparison to intravenous administration, but opioids may still be absorbed at high concentrations, resulting in severe opioid toxicity or death.

Conditions Leading to Ketene Formation in Vaping Devices and Implications for Public Health.

The outbreak of e-cigarette or vaping use-associated lung injury (EVALI) in the United States in 2019 led to a total of 2807 hospitalizations with 68 deaths. While the exact causes of this vaping-related lung illness are still being debated, laboratory analyses of products from victims of EVALI have shown that vitamin E acetate (VEA), an additive in some tetrahydrocannabinol (THC)-containing products, is strongly linked to the EVALI outbreak. Because of its similar appearance and viscosity to pure THC oil, VEA was used as a diluent agent in cannabis oils in illicit markets. A potential mechanism for EVALI may involve VEA's thermal decomposition product, ketene, a highly poisonous gas, being generated under vaping conditions. In this study, a novel approach was developed to evaluate ketene production from VEA vaping under measurable temperature conditions in real-world devices. Ketene in generated aerosols was captured by two different chemical agents and analyzed by gas chromatography-mass spectrometry (GC-MS) and liquid chromatography with tandem mass spectrometry (LC-MS/MS). The LC-MS/MS method takes advantage of the high sensitivity and specificity of tandem mass spectrometry and appears to be more suitable than GC-MS for the analysis of large batches of samples. Our results confirmed the formation of ketene when VEA was vaped. The production of ketene increased with repeat puffs and showed a correlation to temperatures (200 to 500 °C) measured within vaping devices. Device battery power strength, which affects the heating temperature, plays an important role in ketene formation. In addition to ketene, the organic oxidant duroquinone was also obtained as another thermal degradation product of VEA. Ketene was not detected when vitamin E was vaped under the same conditions, confirming the importance of the acetate group for its generation.

Method Development and Validation of an Aerosol Sampling Technique for the Analysis of Nicotine in Electronic Cigarette Aerosols.

Because of the increasing popularity of e-cigarettes, monitoring the e-cigarette market has become important for national health authorities to guarantee safety and quality. In the EU, the Tobacco Products Directive requires emission studies for e-cigarette products. The absence of industry guidelines for studying these emissions and the lack of proper validation in the literature led us to develop and validate a method using the total error approach for the determination of nicotine in e-cigarette aerosols. A commercial vaping device was used to generate aerosols, which were then collected on Cambridge filter pads and measured for nicotine concentration by UHPLC-DAD after extraction. The method was successfully validated by generating accuracy profiles, which show that the β-expectation tolerance intervals remained below the acceptance limits of ±20%. Within-run repeatability and intermediate precision were considered acceptable since the highest RSD value obtained was below 5%. The method was applied to 15 commercial e-liquids. A complete validation of a method for the analysis of e-cigarette emissions is presented, including several parameters that impact the accuracy and reproducibility. Similar systematic approaches for method development and validation could be used for other e-cigarette emission analysis methods to ensure the reliability of the measurements.

Vaping Frequency in Young Users: The Role of Gender and Age Among Regular Users

Background: Vaping is popular among adolescents and emerging adults; however, little is known about regular vaping patterns in older adolescents and emerging adults. Objective: The current study explored whether gender and age are associated with nicotine-based vaping frequency to ascertain ascertaining which subgroups of youth are most at-risk for frequent use. Methods: In a cross-sectional survey, participants using nicotine-based vaping devices (N=535, age range 16-24) reported frequency measured as vaping days in a week, number of episodes during which participants vaped, and puff numbers for each episode. A two-way multivariate analysis of variance was used to test the effects and interactions of gender and age groups on the three frequency outcomes. Results: Emerging adults and males vaped more frequently than their older adolescent and female counterparts, respectively. Specifically, emerging adults vaped more days per week in comparison to older adolescents, whereas males vaped more days per week and had more vaping episodes per day relative to females. Further, emerging adult males had more vaping episodes in comparison to other subgroups, and adolescent females as well as emerging adult males took more puffs per episode in comparison to emerging adult females. Conclusion: Vaping differences among subgroups suggests the need for policies to reduce regular nicotine vaping targeted toward specific gender and age groups.

An Internet Snapshot Survey Assessing the sale of Synthetic Cannabinoid Receptor Agonists for use with Electronic Vaping Devices

IntroductionSynthetic cannabinoid receptor agonists (SCRAs) are associated with significant toxicity and are increasingly used in electronic vaping devices. We assessed the availability of SCRA vaping products to UK purchasers on the surface web.MethodsAn internet snapshot survey was performed between October 2022 and January 2023 on ‘google.com’ using the search terms “buy c-liquid vape”, “buy herbal incense vape liquid”, “buy cannabis vape liquid”, “buy hashish vape liquid”, “buy K2 vape liquid”.Results62 websites selling 128 SCRA vaping brands were identified. Most were purportedly based in the USA (41 websites, 66%) and most sold other controlled substances. Purchase incentives offered included discreet packaging (38, 61%), discounts for bulk purchase (34, 55%) and tracked delivery (30, 48%). Many websites stated SCRA products were: not for human consumption (41, 66%), for research purposes only (15, 24%), or legal (28, 45%). Websites sold a median (IQR) of 16 (7–25) SCRA vaping brands. Almost all were bottles of vaping liquid (1220/1225, 99.6%). The most common bottle size was 5mL (60%), the median (IQR) total volume of SCRA liquid per sale was 50mL (10–200mL). Median (IQR) price was £3.39/mL (£2.01/mL– £5.29/mL). Price decreased with increasing volume purchased (£6.58/mL for ≤ 5mL, £1.60/mL for > 200mL).ConclusionSCRA vaping products are easily obtainable online, in both small and bulk quantities. Information provided to purchasers on safety and legality is lacking or misleading. Further studies are needed to confirm the chemistry of these products. Policymakers should consider steps to limit the potential harm caused by the purchase and use of these products.

E-Cigarette Aerosol Alters Pulmonary Surfactant Function

Introduction: E-cigarette (EC) and vaping use continue to remain popular, particularly in young populations despite several clinical reports of vaping associated lung injury. One of the first compounds that EC aerosols comes into contact within the lungs during a deep inhalation is pulmonary surfactant. A complex mixture of lipids and proteins, surfactant reduces surface tension in the lungs maintaining compliance and preventing collapse. Currently, information on how EC aerosols impacts pulmonary surfactant remains limited, particularly in the in vivo scenario. We hypothesized that exposure to EC aerosol will impair the surface tension reducing ability of surfactant. Methods: In vitro EC aerosol exposure : Bovine Lipid Extract Surfactant (BLES) was used as a model surfactant in a direct exposure syringe system. BLES (2ml) was placed in a syringe (30ml) attached to an EC. The generated aerosol was drawn into the syringe and then expelled, repeated 30 times. In vivo EC aerosol exposure : Male and female Wistar rats were exposed to vehicle or menthol flavoured EC aerosol. Rats were exposed for 15 minutes for either a single or multiple (up to 8) exposures, with control animals receiving room air. Animals were euthanized and bronchoalveolar lavage was performed to collect surfactant. Analyzing surfactant function: Samples underwent dynamic compression and expansion, and biophysical analysis after exposure, completed using a constrained drop surfactometer (CDS). Results: Significant increases in minimum surface tensions were observed after exposure to EC aerosol across 20 compression/expansion cycles. Surfactant function was altered in vitro independent of vaping device, temperature, or inclusion of nicotine. Vehicle aerosol exposure produced alterations in surfactant properties, however addition of menthol flavouring significantly increased surface tensions compared to control and vehicle exposure. Preliminary in vivo studies indicate that aerosol exposure is well-tolerated by both male and female animals. Further experiments will analyze the function of surfactant isolated from these animals. Discussion: EC aerosols alter surfactant function through increases in minimum surface tension in vitro. This effect was more pronounced with menthol flavoured EC aerosol. It is anticipated that our in vivo experiments will corroborate these findings. Ultimately, impairment of surfactant due to EC aerosol exposure may contribute to lung dysfunction and susceptibility to further injury. Western University, NSERC, OGS.

The e-cigarette assessment for youth-Revised (EAsY-R): Preliminary results of a pilot study of measure refinement via cognitive interviewing.

The prevalence of youth vaping has, in a relatively short time, become an "epidemic." In the wake of such labeling by the Surgeon General, a number of important examinations of vaping have been conducted. These have largely focused on high school and college-age youth as this demographic shows the greatest prevalence of use. Nonetheless, no measure has been made available which might allow for the comprehensive assessment of quantity and frequency of vaping among this age group, thus aiding in standardization across settings. The current study utilized cognitive interviews with high school and college-age youth who use vaping devices to inform the preliminary development of such an assessment. The sample consists of eight students between the ages of 15 and 24 (Mage = 18.75, SD = 2.73, 62.5% female, 75.0% Hispanic/Latino/a/x, 100.0% White). Interviewing and measure refinement were conducted in a two-phase iterative fashion. Suggestions made during cognitive interviews resulted in the refinement of assessed content type, updated categories and pictures of vaping devices, as well as updated and age-relevant terminology. Further, instructions were streamlined, and assessment items and multiple-choice options were refined to maximize clarity and to minimize participant confusion. The result of this study, the E-Cigarette Assessment for Youth Revised, is a unique tool for standardizing examinations of the quantity and frequency of vaping behaviors among high school students and college-age youth.

ALARMING CONCERNS SURROUNDING THE RISING TREND OF ELECTRONIC NICOTINE DELIVERY SYSTEM (ENDS).

The surge in popularity of Electronic Nicotine Delivery Systems (ENDS), commonly known as e-cigarettes or vaping devices, has become a matter of urgent concern for public health officials, clinicians, and researchers. While initially marketed as a safer alternative to traditional tobacco products, mounting evidence suggests that the rapid adoption of ENDS poses serious health risks, especially among the youth. This editorial highlights some of these pressing concerns, urging the medical community to prioritize research and advocacy to address the potential long-term consequences of ENDS use.

Prevalence of Adverse Respiratory Symptoms Among E-Cigarette Users in Saudi Arabia – A Cross-Sectional Study

ABSTRACT Electronic cigarettes, frequently referred to as e-cigarettes, have emerged as a controversial and rapidly growing phenomenon in the realm of tobacco and nicotine consumption worldwide. This study reports the prevalence of respiratory symptoms among e-cigarette users. This study also helps to understand the potential harmful effects and importance of quitting e-cigarette smoking. An observational cross-sectional study was carried out in Saudi Arabia. The study period was from September 2022 to August 2023. The sample size was 447 participants. Among recent e-cigarette users in this Saudi study, usage varied, with 44.1% using 1–5 days, 33.6% using 6–30 days, and 22.4% using e-cigarettes previously but not in the previous month. Vape devices were predominant (42.7%). There were significant associations emerged between e-cigarette use frequency and symptoms such as fatigue, breathlessness, and shortness of breath. E-cigarette use was notably linked to asthma-related symptoms, underscoring its concerning impact on respiratory health (P < 0.05). E-cigarette consumption has a significant impact on respiratory effects and specifically asthma-related symptoms among this Saudi population.
