The team of researchers, in the pilot clinical trial have found that those who smoked e-cigarettes twice a day for just a month had higher levels of chemicals such as propylene glycol in their blood. This was associated with inflammatory changes in their lungs. The count of the inflammatory cells in their lungs rises over time, speculate the researchers. However, they agree that this was a small study of a short duration and the magnitude of the changes noted in the lungs were small.
