A new study finds e-cigarettes are associated with significantly less quitting among smokers, CBS News reports. Adult smokers who used e-cigarettes were 28 percent less likely to stop smoking regular cigarettes, researchers found.
The findings, published in The Lancet Respiratory Medicine, are the largest to date to address the question of whether e-cigarettes help smokers quit.
“E-cigarettes should not be recommended as effective smoking cessation aids until there is evidence that, as promoted and used, they assist smoking cessation,” said lead researcher Dr. Sara Kalkhoran, who was at the University of California, San Francisco (UCSF) when the research was conducted. She is now at Massachusetts General Hospital and Harvard Medical School.
