Daily use of electronic cigarettes is associated with nearly a doubling of the odds of a heart attack, according to a new study led by UC San Francisco.Getting information on timing requires longitudinal studies in which people are followed forward in time, often for many years.These studies take a long time to do (because you have to wait for time to pass) and are much more expensive to do than cross-sectional studies.These policies include increased cigarette excise taxes (which result in higher cigarette prices), restrictions on smoking in public places and at private worksites, and limits on the availability of tobacco products to youths.The data employed in this research are taken from the 1992, 1993, and 1994 surveys of eighth, tenth, and twelfth grade students conducted by the University of Michigan's Institute for Social Research as part of the Monitoring the Future Project.Thus, the effects of e-cig use that we estimate are I don't know when the paper will be published. [Epub ahead of print] In the data you looked at is it possible to tell if e-cigarette use was initiated before the myocardial infarction?It takes a long time from initial submission to publication and no author has control over that process. From the abstract it doesn't seem to be able to tell when e-cigarette use was initiated or when the MI happened. That is one of the limitations of all cross-sectional studies, which are a snapshot in time.This is the first evidence of a substantial, human health impact of the popular devices that were first introduced about a decade ago, indicating that e-cigarettes may be more dangerous than previously thought.The new study of nearly 70,000 people found that heightened heart attack risk for e-cigarettes is on top of the effects of conventional cigarettes, which by themselves nearly triple the odds of heart attack risk when smoked daily.That is why the cross-sectional studies are always done first.Finding associations as we did between daily e-cig use and MI demonstrates the need for longitudinal studies.
