The percentage of US adults ages 18 to 24 who used e-cigarettes increased from 5.2% in 2017 to 7.6% in 2018, while e-cigarette use was not significantly different among middle-aged and older adults, according to a study in JAMA Internal Medicine. Researchers also found rising e-cigarette use among men, former cigarette users, non-Hispanic Asians and those whose family incomes were four or more times above the poverty level.
