Aug. 28, 2012 (Munich, Germany) — Electronic cigarettes do not appear to be bad for your heart, according to the first study to look at the effects of smoking e-cigarettes on heart function.
The devices — battery-powered metal cartridges that simulate the effect of smoking by heating nicotine-containing liquid into vapor — can be helpful to smokers trying to kick the habit, says researcher Konstantinos Farsalinos, MD, of the Onassis Cardiac Surgery Center in Athens, Greece.
