The Health Promotion Administration (HPA) expressed concern over the rising use of e-cigarettes among adolescents, as a survey a year ago showed that 80.9 percent of e-liquids contained nicotine and some also contained harmful or potentially harmful ingredients.

The MRI revealed that about 17.5 percent less blood was flowing through the large femoral artery that runs through the thigh and leg. Counseling on smoking cessation, the harmful effects of both e-cigarette and conventional cigarette smoking, and dependable, trusted methods for quitting should all be a standard part of a pharmacist's visit with these patients.

E-cigarettes, often marketed as safe alternatives to smoking tobacco cigarettes, have increased in popularity in the United Kingdom over the past few years.

The researchers then performed a statistical analysis to determine group differences in vascular function before and after vaping.

More research is needed to address the potential long-term adverse effects of vaping on vascular health, but he predicts that e-cigarettes are potentially much more hazardous than previously assumed. In a previous study, they found that vaping nicotine-free e-cigarettes increased signs of inflammation and a form of tissue damage known as oxidative stress, which returned to normal levels in one to three hours.

The researchers applied a cuff to the participants' thighs to constrict the blood vessels, measuring how quickly blood flowed following its release and using an MRI procedure to observe changes in vascular function. They observed, on average, a 34% reduction in the femoral artery's dilation.

Venous oxygen reduced by 20 per cent, while blood acceleration also fell by 25.8 per cent after the cuff was released.

Their findings come amid an alarming slew of lung disease cases among patients who have one thing in common: vaping, whether it be using e-cigarettes infused with nicotine, cannabis or something else.

"But the solvents, flavourings and additives in the liquid base, after vapourisation, expose users to multiple insults to the respiratory tract and blood vessels", he said.

"E-cigarettes are advertised as not harmful, and many e-cigarette users are convinced that they are just inhaling water vapor", Caporale said.

"I would warn young people to not even get started using e-cigarettes".

"While e-cigarette liquid may be relatively harmless, the vaporisation process can transform the molecules-primarily propylene glycol and glycerol-into toxic substances", said Felix W. Wehrli, Professor at the University of Pennsylvania in the US. To the contrary, says a report on the 2018 National Survey on Drug Use and Health, e-cigarettes may be contributing to the downward trend in smoking.
