Smoking e-cigarettes has become increasingly common in Sweden, especially among young people. Last year, 45 percent of boys and 37 percent of girls in grade two said they were testing or using e-cigarettes, according to a report from CAN.
As of late July, the World Health Organization (WHO) warned that electronic cigarettes "are undoubtedly harmful". Others think it is a healthier alternative to regular cigarettes. What most people agree on anyway is that more research is needed to provide a comprehensive picture of how e-cigarettes affect us.Impaired blood circulation
A new study, published in the journal Radiology, shows that e-cigarettes affect the body after only one use.
A total of 31 young healthy people who did not smoke participated in the study. Participants were examined with magnetic X-ray after using e-cigarettes without nicotine in. Among other things, it could be seen that blood circulation in the femoral artery deteriorated immediately after use.More studies needed
However, the changes in the blood vessels were not permanent.
- After a few minutes, everything is restored to normal. You could say that it is not a big deal, that nothing happens, but if any road couple (smokes e-cigarettes, red. Notice) regularly for a long time, it is possible that it does not return to normal so easily , says Felix W. Wehrli, professor of radiological science and biophysics, who is one of the authors, to CNN.
To see how blood vessels are affected in the long term, more studies are therefore needed, according to the researchers. The researchers were also unable to say with certainty which or which chemicals in the e-cigarette led to the changes.
