Dear Dr. Roach: My teens keep smoking all these flavored, ethereal wand vapors. They claim it tastes good and even try tricks with the vapor. Im a concerned parent as I hear these are dangerous magic cigarettes. I would like to know more about them and get your advice on how to deal with these unruly teens. H.R.
Answer: Vaping has become increasingly prevalent, with 1.7 million high school students (and almost 11 million overall adults in the U.S.) using these devices. One popular brand is called JUUL, but they also are called vape pens, e-cigarettes or e-hookahs. They are essentially drug delivery devices for nicotine, an addictive and highly toxic substance. (Not all liquids used for vaping contain nicotine, although some labeled nicotine free were found to have nicotine. Cannabis also may be used in a vaping device.)
