How to report a problem with tobacco?

If you experience a problem with any tobacco product, such as an unexpected health or safety issue, report it online using the Safety Reporting Portal.

You can also report problems with the components and parts of tobacco products. The FDA website has more information on what to include in a report.

Is the FDA concerned about respiratory illnesses?

The FDA remains deeply concerned about these respiratory illnesses and deaths and is working closely with the CDC, as well as state and local public health partners, to investigate them as quickly as possible.

While some cases in each of the states are similar and appear to be linked to vaping product use, more information is needed to determine what is causing the respiratory illnesses.

Does the CDC test vaping?

CDC will conduct aerosol emissions testing of e-cigarette, or vaping, products. FDA is analyzing e-liquids for the presence of a broad range of chemicals. Analysis of both aerosol emissions and e-liquids will complement each other, and together will help improve our understanding of exposures among case patients associated with the lung injury outbreak.

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

What is the term for the accumulation of endogenous cellular lipid material from epithelial injury?

The fine cytoplasmic vacuoles encountered in the macrophages actually represent the accumulation of endogenous cellular lipid material from epithelial injury, a process referred to as endogenous lipoid pneumonia. Endogenous lipoid pneumonia is seen in a variety of settings including acute lung injury, obstructed airways, and infections [23–25].

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.

Is vaping a lung disease?

Although lung diseases caused by vaping have been reported since the modern invention of the electronic cigarette , in the summer of 2019, patients began to present to health care centers at epidemic levels with an acute respiratory illness relating to vaping, which the Center for Disease Control termed E-cigarette or vaping product use-associated lung injury (EVALI). This review discusses electronic nicotine delivery systems as well as the etiology, clinical presentation, imaging findings, pathologic features, treatment, and long-term consequences of EVALI. We conclude with the practical impact EVALI has had on the practice of pathology.

Data from patients who did undergo bronchoscopy has so far failed to identify the mechanism causing lung injuries.
