Vaping is linked to a substantially increased risk of COVID-19 among teenagers and young adults, according to a new study led by researchers at the Stanford University School of Medicine.

The study, which will be published online Aug. 11 in the Journal of Adolescent Health, is the first to examine connections between youth vaping and COVID-19 using U.S. population-based data collected during the pandemic.

Among young people who were tested for the virus that causes COVID-19, the research found that those who vaped were five to seven times more likely to be infected than those who did not use e-cigarettes.

"Teens and young adults need to know that if you use e-cigarettes, you are likely at immediate risk of COVID-19 because you are damaging your lungs," said the study's senior author, Bonnie Halpern-Felsher, PhD, professor of pediatrics.

Young people who had used both cigarettes and e-cigarettes in the previous 30 days were almost five times as likely to experience COVID-19 symptoms, such as coughing, fever, tiredness and difficulty breathing as those who never smoked or vaped. This may explain why they were also more likely to receive COVID-19 testing, said Halpern-Felsher, especially given that in May, many regions limited COVID-19 testing to people with symptoms. Depending on which nicotine products they used and how recently they had used them, young people who vaped or smoked, or both, were 2.6 to nine times more likely to receive COVID-19 tests than nonusers.

Among the participants who were tested for COVID-19, those who had ever used e-cigarettes were five times more likely to be diagnosed with COVID-19 than nonusers. Those who had used both e-cigarettes and conventional cigarettes in the previous 30 days were 6.8 times more likely to be diagnosed with the disease. The researchers did not find a connection between COVID-19 diagnosis and smoking conventional cigarettes alone, perhaps because the prevalent pattern among youth is to use both vaping devices and traditional cigarettes. Other research has shown that nearly all nicotine-using youth vape, and some also smoke cigarettes, but very few use cigarettes only, Halpern-Felsher said.
