According to the National Youth Tobacco Survey, more than 20% of US high schoolers vaped in 2018—an alarming increase of 78% over the previous year. Preliminary data from this year’s survey suggest a continued rise in youth e-cigarette use. Recent studies suggest that young people who vape are more likely to become smokers. Public health officials warn of an epidemic, the full consequences of which are not yet known. But the most dangerous aspect of vaping might not be what it does to the body, but rather what it does to the body politic.
