E-cigarettes and COVID-19
A recent survey of 4,351 adolescents and young adults in the United States showed that a COVID-19 diagnosis was five times more likely among those who had ever used e-cigarettes, seven times more likely among conventional cigarette and e-cigarette uses, and nearly seven times more likely among those who had used both within the past 30 days .
Perhaps not surprisingly, adolescents and young adults with asthma who also vape may be at especially high risk for COVID-19, but the exact effect may be hard to pin down with current levels of evidence.
“Prior to the pandemic we did see both new-onset asthma and asthma exacerbations in teens who reported either vaping or dual use with tobacco products,” Dr. Cataletto said. “However, numbers were small, were confounded by the bias of subspecialty practice, and the onset of the pandemic, which affected not only face-to-face visits but the opportunity to perform pulmonary function testing for a number of months.”
Dr. King noted: “There is an emerging body of science that does indicate that there could be some respiratory risks related to e-cigarette use, particularly among certain populations. ... That said, there’s no conclusive link between e-cigarette use and specific disease outcomes, which typically requires a robust body of different science conducted in multiple settings.”
He said that e-cigarette vapors contain ultrafine particles and heavy metals that can be inhaled deeply into the lungs, both of which have previously been associated with respiratory risk, including complications from asthma.
An ounce of prevention
“When it comes to cessation, we do know that about 50% of youth who are using tobacco products including e-cigarettes, want to quit, and about the same proportion make an effort to quit, so there’s certainly a will there, but we don’t clearly have an evidence-based way,” Dr. King said.
Combinations of behavioral interventions including face-to-face consultations and digital or telephone support can be helpful, Dr. Cataletto said, but both she and Dr. King agree that prevention is the most effective method of reducing e-cigarette use among teens and young adults, including peer support and education efforts.
Asked how she gets her patients to report honestly about their habits, Dr. Cataletto acknowledged that “this is a challenge for many kids. Some are unaware that many of the commercially available e-cigarette products contain nicotine and they are not ‘just vaping flavoring.’ Ongoing education is important, and it is happening in schools, in pediatrician’s offices, at home and in the community.”
Dr. Cataletto and Dr. King reported no relevant conflicts of interest. Dr. Cataletto serves on the editorial advisory board for Chest Physician.
