As the country’s vaping crisis continues to grow, some smokers who picked up e-cigs to break their addictions — including youngsters enticed by fruit and mint varieties — are now putting down their digital devices in favor of their former vices: traditional cigarettes. 21-year-old Lucas McClain of Arlington, Virginia, told California Healthline that he started using Juul products in high school as an alternative to cigarettes on the premise that it was a less lethal alternative. But he bought his first pack of smokes in years last month — and now feels as if he’s going backward. “Juul made my nicotine addiction a lot worse,” McClain said. “When I didn’t have it for more than two hours, I’d get very anxious.” That some young smokers are now “going back to the product” they were trying to quit isn’t a surprise, according to Pamela Ling, a professor of medicine at the University of California-San Francisco. But it’s alarming, as tobacco smoke still contains a deadly mix of more than 7,000 chemicals, 70 of which can cause cancer, according to Centers for Disease Control and Prevention data.
