It appears that if high school students smoke e-cigarettes, they are more likely to start smoking regular cigarettes, study results show.
The students were asked whether they had ever tried e-cigarettes, cigarettes, cigars, pipes or hookah, and how many days each product was used in the past 30 days, said Jessica L. Barrington-Trimis, Ph.D., of the University of Southern California, Los Angeles, and her associates.
Data were gathered among high school students participating in the Southern California Children’s Health Study, which resulted in complete data for 152 students who never used e-cigarettes and 146 e-cigarette users. Results showed e-cigarette users were six times more likely to subsequently smoke cigarettes than were those who never smoked e-cigarettes. E-cigarette users were five times more likely to subsequently use a cigar, pipe,or hookah than were those who never smoked e-cigarettes.
“Because e-cigarette use is common in adolescents and young adults, further prospective follow-up of this and other cohorts is needed to determine whether e-cigarette use will increase population rates of cigarette and other combustible tobacco products and their associated burden of disease,” the investigators concluded.
