Update: E-Cigarette Safety

As the European Respiratory Society held their annual convention, several research studies made the health news, including e-cigarettes and vaping. The appeal of e-cigarettes is that they seem to be safe–you’re not actually burning tobacco with its associated chemicals and inhaling that into your lungs. E-cigarettes remove all that bad stuff and associated negative health effects. Or do they?

In the first study, researchers recruited 15 subjects who had smoked cigarettes occasionally, fewer then 10 per month; subjects had also never used e-cigarettes. They were asked to smoke e-cigarettes for 30 minutes in a random order on different days; once with nicotine, the other without. The researchers measured blood pressure, heart rate, and arterial stiffness immediately after smoking the e-cigarettes and then two and four hours later.

In the first 30 minutes after smoking e-cigarettes with nicotine, there was a significant increase in blood pressure, heart rate, and arterial stiffness. That didn’t happen after the e-cigarettes without nicotine. While this is a small pilot study, it seems that vaping nicotine can impact the cardiovascular system in the same way regular cigarettes do.

What are you prepared to do today?
