Dr. Lauren Dutra, UC, San Francisco - E-Cigs and Real Cigs

E-Cigarettes are rapidly gaining popularity.

Lauren Dutra, post-doctoral scholar at the University of California, San Francisco's School of Medicine, is studying the correlation between usages of these different tobacco products.

Lauren Dutra’s research interests include disparities in smoking and smoking-related disease, the targeted marketing of vulnerable populations by tobacco companies, and new tobacco products, such as e-cigarettes.  She has a Doctor of Science from the Harvard School of Public Health and is a Social Epidemiologist by training. Her dissertation focused on experiences of injustice and smoking behavior in South Africa and the U.S..   Prior to obtaining her doctorate, she received a Masters in Mental Health and Behavioral Medicine from Boston University and worked as a psychotherapist/health behavior counselor.   Lauren has first-author publications in Social Science & Medicine, JAMA Pediatrics, and Tobacco Control, as well as publications in Preventive Medicine, Diabetes Care, and the Journal of Cognitive Psychology.

Dr. Lauren Dutra - E-Cigs and Real Cigs

Along with my colleague Dr. Stanton Glantz, I authored a study examining the correlation between electronic cigarettes use and conventional cigarette use among US adolescents.

We analyzed two cross-sectional nationally representative samples of U.S. teens collected by the Centers for Disease Control.

The use of e-cigarettes doubled between 2011, when over 17,000 U.S. middle and high school students were surveyed, and 2012, when over 22,000 students were surveyed.

We found that teens who had ever used e-cigarettes were more likely to be current cigarette smokers than those who had never used e-cigarettes. Among ever smokers (teens who had smoked 100 cigarettes or more in their lifetimes), teens who used e-cigarettes were more likely to be planning to quit smoking cigarettes in the next year.

 However, these teens were less likely to have abstained from cigarette smoking in the past 30 days, 6 months, or year.

 In other words, they were less likely to be former cigarette smokers. Smokers who used e-cigarettes also tended to be heavier smokers, smoking, on average, more cigarettes per day.

We also found that 20% of middle school students who had ever tried an e-cigarette had never tried cigarette smoking, not even a puff.

Only 7% of high school students who had ever tried e-cigarettes had never tried cigarette smoking. These figures suggest that some students are first introduced to nicotine through e-cigarettes, not conventional cigarettes.

However, additional research is needed to determine whether e-cigarette use leads to increased cigarette smoking among teens.
