Many people consider e-cigarettes a healthier alternative to regular cigarettes. But according to a new study, they could increase your risk of heart attack and stroke if they contain nicotine, reported The Independent.
Researchers from the Karolinska Institute, a medical university in Stockholm, found that vaping devices containing nicotine can result in a stiffening of the arteries, as well as an increase in heart rate and blood pressure.
Vaping is now a £1billion industry in the UK, and the market is still growing too.
E-cigarettes are commonly considered to be a stepping stone for people trying to quit smoking entirely, but the new study suggests they may be more dangerous than previously thought.
The researchers recruited 15 healthy volunteers who’d never smoked e-cigarettes before for their study.
After running a series of tests, they found that 30 minutes after vaping, the participants had experienced a significant increase in blood pressure, heart rate and arterial stiffness.
These side effects weren’t experienced by the participants who’d smoked e-cigarettes without nicotine though.
Lead researcher Dr Magnus Lundback said: “The number of e-cigarette users has increased dramatically in the last few years. E-cigarettes are regarded by the general public as almost harmless.
“The industry markets their product as a way to reduce harm and to help people to stop smoking tobacco cigarettes. However, the safety of e-cigarettes is debated, and a growing body of evidence is suggesting several adverse health effects.
“The results are preliminary, but in this study, we found there was a significant increase in heart rate and blood pressure in the volunteers who were exposed to e-cigarettes containing nicotine. Arterial stiffness increased around threefold in those who were exposed to nicotine-containing e-cigarettes compared with the nicotine-free group.”
