harm of electronic cigarettes

Radiologists have identified lung diseases caused by smoking vapes and other e-cigarettes.

The American Journal of Roentgenology has published a study of the effects of vaping, hookah, e-cigarettes and other nicotine delivery systems by a group of researchers from the University of California, San Francisco. 

The study was carried out based on observation of 19 clinical cases with computed tomography and a review of the literature describing 15 pulmonary pathologies. All of them meet the definition of a case of pulmonary injury from the use of electronic cigarettes, which is characterized by “pathological changes identified in the framework of radiological studies”. As a result, the following diseases were identified, caused by the use of electronic nicotine delivery systems (ENDS):

hypersensitivity pneumonitis;

diffuse alveolar bleeding;

acute eosinophilic pneumonia;


lipoid pneumonia;

giant cell interstitial pneumonia.

Diseases are manifested mainly by coughing, shortness of breath, bloody bronchoalveolar secretions and progressive respiratory failure. CT scans of smokers showed foci of various types of darkening: ground-glass opacity, nodular compaction and other signs of lung damage. After cessation of antigen inhalation on CT, noticeable improvements were observed.

Electronic nicotine delivery systems were originally intended to replace traditional cigarettes. Unfortunately, they have not become a safe alternative to smoking. It is now known that an electronic cigarette is as harmful as a regular one. A highly dispersed vapour, or aerosol, formed in a vape is a suspension of liquid droplets in the air. Aerosols contain metals such as cobalt. Even within the framework of this study, a case of a rare pathology was discovered – pneumoconiosis, caused by trace amounts of cobalt in an e-cigarette. “Juices” also contain other harmful substances – diacetyl, aldehydes and alcohols, and when creating mixtures, complex and very dangerous compounds arise.

If signs of pulmonary disease are found, an e-cigarette lover should consult a doctor and think about quitting the habit.
