E-cigarettes with Higher Nicotine Associated with Regular Smoking in Teens


Published Date : Oct 24, 2017

A new U.S. study published in JAMA Pediatrics has revealed that teens using e-cigarettes or those who vape could increase the odds of developing a regular smoking habit, if the e-liquid contains higher nicotine concentrations. Adam Leventhal, co-author of the study and Health, Emotion, and Addiction Laboratory director at the University of Southern California, has suggested that the connection between vaping e-cigarettes and smoking traditional cigarettes later among youth may be blamed on nicotine in e-cigarettes.

Leventhal has said that it is a matter of concern for teens continuously exposed to nicotine, even via e-cigarettes, because the ingredient could escalate the risk of depression and attention problems in adolescents and pose harm to their developing brain.

High Nicotine Liquid in E-cigarettes Linked to 65% Higher Risk of Developing Regular Vaping Habit

During the JAMA study, the researchers focused on teens recently vaping to check if their use of conventional cigarettes and e-cigarettes has been influenced by the measure of nicotine in their e-liquid over a period of six months. By the end of the study, the researchers reported that adolescents vaping e-cigarettes with high nicotine levels were twice as more than likely to develop a habit of smoking conventional cigarettes as those vaping nicotine-free liquid.

181 high school students in Los Angeles were surveyed for the current study during their 10th grade and again in 11th grade. All of the participants had at least vaped once in the last 30 days of the initial survey. Nicotine concentrations scoping from none to 18 mg per ml were reported.
