Скачать или смотреть Teens falling victim to the JUUL effect

Doctors are seeing an increase in vaping among teens and even middle schoolers.

Dr. Beth Ebel, a UW Medicine pediatrician and researcher with the Harborview Injury Prevention and Research Center, says vaping with products that have nicotine "predisposes you to cigarette smoking later on."

Nicotine, once derived from tobacco plants to kill insects, works by altering the nervous system. "We've used it, refined it, concentrated it, and now we have a pure form of one of the most addictive substances known," Ebel says.

One JUUL pod has 20 cigarettes worth of nicotine. Ebel suggests parents learn about vaping and have a discussion with their kids.
