4.9% of American adults living with someone 18 or under reported using e-cigarettes. That’s versus 4.2% of adults living in households without children according to study author Jenny L. Carwile, an epidemiologist at Maine Medical Center, who also pointed out that these adults tend to be older.

They say this could reflect the perception that vaping is safer than smoking combustible cigarettes because teens see the adults in their life vaping and are starting to vape at relatively young ages.

The authors also point out that, in addition to inhaling the aerosol secondhand, there’s a risk that certain chemicals in e-liquids, namely nicotine can be absorbed through the skin or even ingested. Experts warn of this particular risk among young children.

In addition to inhaling the aerosol secondhand, there’s a risk that certain chemicals in e-liquids, namely nicotine, can be absorbed through the skin or even ingested. Experts warn of this particular risk among young children. Dr. Robert Jackler, founder of Stanford Research into the Impact of Tobacco Advertising, previously told CNN that some e-liquids with high nicotine concentrations represent “a huge poisoning risk.” And with the rise in e-cig popularity has come a rise in calls to poison control centers, he added.

To help encourage adult smokers to quit, the FDA is launching a new public education campaign called “Every Try Counts.” It will target smokers aged 25 to 54 who’ve tried to quit smoking in the past year but haven’t been successful.
