Amid all the bad news of the COVID-19 pandemic, one bright spot was the relative resilience of young people. Then came a survey of more than 4,000 people aged 13 to 24 conducted in May: Users of e-cigarettes were five times more likely to be diagnosed with COVID-19 than non-users. 

Since one in five 18- to 29-year-olds reports vaping regularly, the link to COVID-19 triggered a call in Congress for the FDA to clear e-cigarette products from the market for the duration of the coronavirus crisis.
