The Washington Poison center has released its yearly summary of e-cigarette exposure calls.
According to the center, e-cigarette exposures were generally lower in 2015 than in 2014, and received a total of 156 calls.
However, children between 1 and 3 years of age are still the largest affected groups of those affected by e-cigarette exposures.
The vast majority (91 percent) of exposure cases last year happened at their own residences.
