Scientists at The University of Texas Health Science Center at Houston (UTHealth) School of Medicine have discovered critical differences between e-cigarettes that use a greatly simplified heating chamber (but not with the heating coils used by traditional cig-a-day products) and those that use a more robust heating coil with coils and coils integrated in the chamber.

Published today in JAMA Pediatrics the study offers the most comprehensive study of the impact of electronic cigarette vapor over the past several months on health. This study represents the first time weve been able to compare just how different cigarette users experience this modifiable behavior with flavor delivery said corresponding author Dr. Marcus Bae assistant professor of pediatrics and adolescent medicine at McGovern Medical School at UTHealth. Were aware that many people are switching but how much of a difference is there versus traditional cigarette usage is an open question. We wanted to know how e-cigarette usersnon-smokers perceive the taste of a smoke without using tobacco products.

The preliminary results of the study conflict with claims by e-cigarette and vaping companies that demand that their Ingredients Check list includes nicotine and menthol. Were not surprised by these findings since weve seen these changes over the past three years and have expected them. But were now so far removed to what wed consider the definitive answer thats on their web page about the benefits of e-cigarettes said Bae. These chemicals need to be on the government list for reliability.

But the study identified several factors that limit natural taste experience by traditional cigarette-wielding youth. First nicotine cannot be inhaled without smoking tobacco products or by vaping using customized products. Second electronic cigarettes not only dont expose tobacco users to dangerous nicotine levels they also impact the immune system to a degree that may not be clear for non-smokers. Third the spread of e-cigarette use among public health educators and other experts impacted how the products are used and what researchers say. Finally the density and level of nicotine the products provide depend on the users preference.

In keeping with their goal to answer the question among youth about teenagers use of e-cigarettes Bae and colleagues atMichiganders Laboratories have produced a free interactive Web site that answers the most popular questions from smokers and non-smokers.
