E-cigarettes are often promoted as a safer alternative to traditional tobacco cigarettes or even as a cessation tool. The perception that these devices are safer than cigarettes has led to a surge in their use. A 2016 report from the US Surgeon General, for example, noted that 1 in 6 teens now uses e-cigarettes, even as use of traditional cigarettes has dropped in this age group.

Preliminary studies suggest that e-cigarettes may be associated with heart risks. In an e-cigarette, nicotine is heated …
