Vaping, may also have harmful psychological effects with a strong association between vaping, major depression and suicidal behavior as reported in a large new study [22]. The likely contributing culprit, nicotine. Prevalence of lung disease attributable to vaping is likely under reported as cases brought to the CDC are some of the most severe. For now EVALI remains a diagnosis that is made after exclusion of other conditions and needs to be reported to the CDC.
What are the ingredients in vape?
The ingredients of vape that are suspected of contributing to the development of vaping-related illnesses are THC and vitamin E acetate. THC is an ingredient used in many vape products, and many patients experiencing vape-related complications have admitted to using THC-containing products in the past, leading the FDA to believe that THC may play a role in the vape-related illness outbreak. The FDA has issued a public warning to stop using THC-containing vape products, as the compound may be contributing to lung illnesses related to vaping. Specifically, vitamin E acetate is most commonly used as an additive in THC-containing vape/e-cigarette products; vitamin E acetate is an oily chemical added to THC vaping liquids used to thicken or dilute them. A vape-related injury concerning a teenage boy in Canada has recently gained the media’s attention as well. The 17-year-old boy vaped “intensively,” adding THC to his devices. He initially showed symptoms aligning with bronchiolitis (lung condition normally caused by a bacterial or viral infection), but many patients that have vape-related illnesses in the United States have experienced damage to the alveoli; this type of injury was not found. Instead, his case aligned more with an injury called “popcorn lung,” an ailment most commonly seen in factory workers of microwave popcorn plants nearly 20 years ago. This new vape-related case calls for further exploration into the toxicity of vape liquid, as the patient’s condition could have been caused by the THC added to the vaping devices, or the chemical that affected factory workers in the past - diacetyl. Diacetyl is present in many e-cigarette flavors [14]. The American Lung Association has called for the FDA to require that diacetyl and other hazardous chemicals be removed from e-cigarette cartridges.
What is the purpose of vaping?
Vaping was initially marketed as a smoking cessation aid to help with cessation of cigarette smoking. E-cigarettes first took public attention in the mass media for unexpectedly blowing up, causing burns and severe facial damage [6]. In the past decade, a number of alternative vaping products have rapidly gained consumer demand, especially in, adolescents, due to the belief that they are much safer (lower nicotine content) than traditional cigarettes, choice of advertisements different flavors and ease of access to electronic nicotine delivery systems (such as e-cigarettes and vape pens). Except for menthol, the use of flavor additives has been banned from traditional cigarettes, whereas e-cigarettes are marketed in over 7,000 different flavors. Many of those flavors are found in candy and popular soft drinks and, because adolescents are familiar with such flavors, e-cigarettes are appealing to them. Tobacco smoking is associated with vascular endothelial dysfunction in a causative and dose-dependent manner [7]. Data from 5,400 smokers and 2,025 former smokers have found that the average number of cigarettes smoked per day by people who regularly used e-cigarettes fell by 4.4 over about two years, compared with only 2.7 for those who did not use e-cigarettes. Sixty-seven percent more e-cigarette users than non-users quit smoking altogether. However, there were 70% more relapses among former smokers who used e-cigarettes than among those who did not use the devices [8].
When were electronic cigarettes invented?
Electronic cigarettes were first developed in China in the early 2000s and introduced to the US market in 2007 [5]. In the US, the product experienced explosive growth, with the number of electronic cigarette users doubling every year between 2008 and 2012. While traditional cigarettes are smoked through combustion, e-cigarettes are "vaped," and the resultant aerosols potentially contain a reduced number of potentially toxic chemicals, such as nicotine and flavorings such as diacetyl and cinnamaldehyde, as well as byproducts such as formaldehyde and acrolein caused by the potential overheating of propylene glycol, and glycerin.
Does vaping affect the lungs?
The evidence on how vitamin E acetate affects the lungs of vape users is notable because vitamin E acetate has been acknowledged as a majorly harmful chemical that may be contributing to vape-related illnesses and deaths. Lung scans have revealed different outlines of lung parenchyma suggesting possible different processes in injury. One pattern points to lipoid pneumonia which can occur with lipid containing ingredients or oils aerosolized into the airways causing inflammation and compromised function [17]. The respiratory epithelium has a complicated network of extracellular membranes essential for breathing and survival. Surfactant membranes form a stable monolayer at the air-liquid interface, reducing the surface tension at the air-liquid interface, therefore stabilizing the lung against collapse and helping lungs expand. Oil in the lung interferes with this ordered/disordered lipid phase coexistence in lung surfactant with alterations in phase coexistence [18]. The American Medical Association has made calls for a ban on vaping products, and Washington state has now banned vape products containing vitamin E acetate, thought to be linked to illness [19-20]. Although the substance is not banned in the United States and has not been officially declared as a deadly substance, many states are making advances to ban the use of the chemical in vape products. States like Massachusetts are considering a ban on flavored tobacco and vape products, and in New York, Manhattan is expected to become the largest city to ban all vaping flavors except tobacco. Other states that have already banned the use of vitamin E acetate in vape products include Colorado and Ohio. Greater public awareness of this deadly condition helps with implementing comprehensive, population-based interventions for this preventable disease.
Is vaping dangerous?
CDC has detected vitamin E acetate as a chemical of concern among people with the lung injury. Vitamin E acetate is a condensing agent in vaping products, and all injured lung fluid samples appear to harbor this agent. The mysterious outbreak is identified in individuals vaping within the 90 days, ranging over a few days to developing over several weeks. There is growing evidence that vaping is hazardous to your health including immediate health dangers such as death from respiratory causes, long term health effects, cardiovascular events, depression which increases the risk of suicidal thoughts and suicide. This review article summarizes the growing knowledge of acute respiratory complications associated with vaping.
Does vaping cause lung injury?
The New York Times recently reported an analysis of lung fluid samples from 29 patients with vaping-related illnesses (including two who died), and the analysis suggests that vitamin E acetate is a "very strong culprit" in causing lung injuries. The lung fluid samples were collected from patients across the United States so that these findings may have implications nationwide. Moreover, Dr. Anne Schuchat, principal deputy director of the CDC, explained, “For the first time, we have detected a potential toxin of concern, vitamin E acetate, from biological samples from patients… The analysis provided evidence of vitamin E acetate at the primary site of injury in the lungs” [15]. Vitamin E acetate is sticky, giving it the ability to remain in the lungs. THC was also reported to be found in 82% of samples from 28 patients, which was remarkable as THC tends to leave the lungs quickly [16].

What is an end vape?
ENDS, also known as E-cigarettes and vaping devices, were originally developed as a replacement device for conventional tobacco cigarette smokers [1]. However, their success in the arena of smoking cessation has been very limited, and they remain unapproved as cessation tools due to a lack of data demonstrating efficacy relative to currently approved nicotine replacement therapies [2]. The aerosols produced by E-cigarettes are known to cause a variety of deleterious health effects, although more research and long-term studies are still needed [2]. E-devices have rapidly evolved since entering the international market in 2013, with vape pens, box mods, and pod-based devices being the most commonly used vaping devices in 2020 [3]. Although E-cigarettes are used in conjunction with conventional tobacco by many cigarette smokers (dual users), their sole use in young adults and adolescents has skyrocketed [4]. This is concerning as use of tobacco products had been declining worldwide for over 50 years, and now, a new generation of nicotine addicts is being created through these novel vaping devices through the use of appealing flavors and packaging [5]. Even more concerning is that children and teenagers who use E-cigarettes are more likely to smoke conventional tobacco [6].
What is the difference between evali and lipoid pneumonia?
a, bThe histologic distinction between exogenous lipoid pneumonia and electronic cigarette or vaping-associated lung injury (EVALI) is dramatic and distinctive. Exogenous lipoid pneumonia shows numerous lipid vacuoles a, most of which are much larger than individual cells. There is associated fibrosis in which many of the droplets are embedded. Occasional macrophages contain lipid droplets within their cytoplasm. However, the droplets are much larger and more variable (arrow) compared to EVALI, H&E, × 100. Larger lipid vacuoles are surrounded by several multinucleated giant cells and a foreign body giant cell reaction (arrowhead) b, a feature not seen in EVALI, H&E, × 200
Is vaping a respiratory disease?
In the summer of 2019, an acute, mysterious, and deadly respiratory illness related to vaping emerged, primarily in young patients, in the USA. Cases increased dramatically and peaked in late September 2019. The Center for Disease Control and Prevention (CDC) termed the disease causing this epidemic E-cigarette or vaping product use-associated lung injury (EVALI). Prior to EVALI, vaping had been associated with a variety of different pulmonary presentations ranging from lipoid pneumonia to diffuse alveolar hemorrhage, but at low numbers. In this review, we discuss electronic nicotine delivery systems (ENDS) as well as the etiology, clinical presentation, imaging findings, pathologic features, treatment, and long-term consequences of EVALI. We conclude with a discussion on the practical impact EVALI has had on the practice of pathology.
