As the use of e-cigarettes has risen dramatically in the United States in recent years, so have calls to poison centers about them, yet most parents are unaware of potential dangers.
The devices are used like cigarettes but instead of tobacco, they vaporize a liquid mixture of nicotine, glycerin and glycol ethers. If ingested, a teaspoon of this "e-liquid" can be lethal to a child, and smaller amounts can cause nausea and vomiting that may necessitate a trip to the emergency room. In a few cases, exposure to skin has also sickened children.
