Electronic cigarette “vapors” are made of small particles containing chemicals that may cause or worsen acute respiratory diseases, including asthma and bronchitis, among youth, according to a new study by RTI International.

Jonathan Thornburg, Ph.D., senior research engineer and program manager at RTI International, can comment on the particles emitted by e-cigarettes and how it affects a teen's health. He is part of a research team that is studying the particles in e-cigarette vapors.

Annice Kim, Ph.D., senior social scientist at RTI International, can comment on e-cigarette advertising. She recently co-authored a separate study, published in the April issue of American Journal of Preventive Medicine, that found ad expenditures tripled from 2011 to 2012.
