The linked article was included in a press release earlier today by my employer (The Hospital of The University of Pennsylvania).
I found the arguments presented in the reader comments interesting...
The Ambiguous Allure of the E-Cig In a recent “Room for Debate” in the New York Times, experts weighed in the latest trend of e-cigarettes. Andrew Strasser, MD, associate professor in the department of Psychiatry and director of its Biobehavioral Smoking Laboratory, penned a piece, arguing for more research and regulation. Not all smokers are alike and therefore will respond differently to e-cigarettes, he writes, and there is a paucity of research on how individuals actually use them and if there are any risks or benefits. “Production standards must be enforced so that consumers can be properly informed of the amount of nicotine and other constituents present,” he writes.” Until we have a sense of how the public will actually use the product we must carefully and continually monitor this emerging health issue.”
