Electronic Cigarette Use Among U.S. Adults, 2018.

In 2018, an estimated 8.1 million U.S. adults were current electronic cigarette (e-cigarette) users (1). E-cigarette use is a public health concern (2), and it has been linked to a recent outbreak of lung injury and deaths among adults (3). Although the potential long-term health risks of e-cigarettes are not yet as well-known as they are with cigarettes, e-cigarettes usually contain nicotine, and nicotine is highly addictive (2). Moreover, the most common tobacco product combination among adults is e-cigarettes and cigarettes (4). This report examines e-cigarette use among U.S. adults aged 18 and over by selected sociodemographic characteristics and in relation to cigarette smoking status.
