According to just published research, e-cigarettes that contain nicotine could heighten the risk of suffering a heart attack or stroke.
The new study in Sweden linked vaping devices that contained nicotine to an increase in blood pressure, the heart rate and the stiffening of arteries after 30 minutes use.
However, the e-cigarettes that do not have nicotine did not have any similar effects on users who participated in the experiment.
None of the healthy volunteers (15) who had taken part in the study had used the devices prior to the study.
A doctor who participated in the research said that the number of users of e-cigarettes had increased in a dramatic fashion over the past couple of years. He added that many people in the general public considered e-cigarettes to be harmless.
The adverse effects over the long term of nicotine have been hard to establish for researchers, as it is consumed usually through products containing tobacco, which contain a host of other chemicals as well.
The industry has marketed the product, said the doctor, as a way to lower the harm and help people stop smoking cigarettes containing tobacco.
However, there is a big debate about the safety of e-cigarettes, as growing evidence is now suggesting a number of adverse health effects associated with their use.
Although these adverse effects that were uncovered by the experiments had been only temporary, the doctor said chronic exposure to the devices that have nicotine could produce effects that are permanent.
He continued by saying the results were preliminary, but in the recent study the researchers had found a significant increase in blood pressure and heart rate in those that participated who had been exposed to e-cigarettes that contained nicotine.
Researchers said the arterial stiffness had increased close to threefold in the people who had been exposed to e-cigarettes that contained nicotine compared to those in the group that had been nicotine free.
Another group of physicians released a report that in 2016 stated that the policy of public health should encourage users of tobacco to switch to a product that had a substitute for tobacco.
It added that the hazard to health that arisen from vapor inhalation over the long term form the e-cigarettes that were available today was not likely to exceed 5% of harm that one gets from smoking tobacco.
