One E-Cigarette May Lead to Adrenaline Changes in Heart, Study Finds

For many smokers and non-smokers electronic cigarettes are perceived as being a less harmful or healthier option to regular cigarette smoking, but new research finds just one e-cigarette with nicotine can increase adrenaline levels.

Researchers studied 33 healthy adults who were not current e-cig or regular cigarette smokers. On different days, participants would vape with nicotine, without nicotine or a sham device, then their cardiac adrenaline activity was measured.

The senior author of the study said whether a person has heart disease or not, a pattern of high adrenaline levels in the heart increases risk of death and they hope the study discourages nonsmokers from vaping.
