Nearly 11 Million US Adults Are Using E-Cigarettes A new study says roughly 10.8 million U.S. adults are currently using e-cigarettes. The study adds more than half of them are under 35 years old, and one in three users are vaping daily. Research shows that 5.9% of men reported current e-cigarette use compared with 3.7% of women. The study goes on to say that people with chronic medical problems are also more likely to vape than individuals
without health issues. Overall, 1.4 percent of people in the study who never smoked traditional cigarettes used e-cigarettes. E-cigarettes containing nicotine can be addictive like traditional cigarettes. Even without nicotine, research says ingredients in e-liquids could be linked to serious breathing problems.
