A new warning from the Centers for Disease Control: increasing number of people, especially young children, are being injured after coming into contact with e-cigarettes.
The problem occurs when people touch or accidentally swallow the liquid nicotine found inside e-cigarettes.
"People do not appreciate the level of toxicity that is present in this e-liquid. This is concentrated nicotine," said Dr. Tim McAfee, Centers for Disease Control Office on Smoking and Health.
As sales of e-cigarettes have risen in recent years, so have calls to poison control centers related to that concentrated nicotine, or e-juice, as it's sometimes called.
The Centers for Disease Control released a report finding just one call to a poison center related to e-cigarettes in September 2010. In February 2014, there were 215.
"The symptoms that people are reporting are predominantly nausea and vomiting and eye irritation," said Dr. McAfee.
All you have to do is touch the liquid nicotine to develop symptoms. Users "vape" the liquid and can switch out the containers of e-juice for different flavors, like cotton candy and bubble gum.
The new report offers a warning in particular for adults to keep the products away from children.
Kids under age six accounted for more half of the e-cigarette-related calls to poison centers.
A industry spokesperson says there are labels on products clearly warning users of the potency of the liquid nicotine and that more education is needed to keep e-cigarettes out of reach from children.
