Adolescents who use e-cigarettes are much more likely to smoke conventional cigarettes, a study released by the U.S. Centers for Disease Control and Prevention found.
The results show 43.9 per cent of sixth- through 12th-graders who had used e-cigarettes said they intended to light up tobacco cigarettes during the next year, compared with 21.5 per cent who had never used the electronic nicotine delivery systems.
Overall, more than 263,000 adolescents who had never smoked before used e-cigarettes in 2013, up from 79,000 in 2011, the CDC reported in a study in the journal Nicotine and Tobacco Research. The data come from the agency's national youth tobacco surveys for 2011-2013.
