The harm reduction benefits of E-cig's continues to mount. A recent research study has found that they are easier to quit than smoking tobacco. A 2016 report by the Surgeon General called for more research on the use and health impact of e-cigarettes. To that end, health experts and government regulators have been awaiting the first results of the Population Assessment of Tobacco and Health (PATH) study, a comprehensive, ongoing national survey of tobacco use among more than 30,000 young people and adults.To compare e-cigarette and cigarette dependence, researchers at Penn State College of Medicine analyzed responses to surveys taken in the PATH study. In these responses, they looked for daily or almost-daily users of either e-cigarettes or cigarettes.Out of 32,320 who answered the survey, 3,586 fit the study criteria. Among those, about 5 percent exclusively used e-cigarettes and about 95 percent exclusively smoked cigarettes. Of the e-cigarette users, 93 percent once regularly smoked cigarettes and about 7 percent experimented with cigarette smoking.Compared with cigarette smokers, e-cigarette users waited longer to start using their product after waking up. Vapers were less likely to consider themselves addicted, to have strong cravings or to feel like they really needed their product. They were also less likely to say they found it difficult to refrain from using their product in restricted places.
