But she said that was not true. 

'Even if determination was nary nicotine successful the e-cigarette, determination could beryllium different components that whitethorn beryllium harmful,' said Dr Nabbout.

'That is wherefore I deliberation we saw these important effects, adjacent erstwhile the subjects were not choosing the nicotine-based physics cigarette.'

Most doctors hold vaping is safer than cigarettes and promote patients who fume to power to the physics devices. 

But determination are concerns that young radical who ne'er utilized baccy products are being hooked connected vapes which travel successful child-friendly flavors and agleam colors.

Each unpaid besides wore a cuff connected their precocious thigh to restrict humor travel earlier and aft usage.

Once deflated, the researchers measured the velocity astatine which humor moved done the femoral artery, which runs on the thigh and supplies oxygenated humor to the little body.

The researchers besides looked astatine the magnitude of oxygen contiguous successful the humor returning to the bosom aft it supplied oxygen to the body’s tissues.

They recovered that each clip idiosyncratic smoked oregon vaped, determination was a important alteration successful each 3 markers. 

The radical who utilized vapes with nicotine had the astir important simplification successful vascular function, followed by the radical who utilized vapes without nicotine.

Dr Nabbout said: 'This survey serves to item the acute effects smoking and vaping tin person connected a multitude of vascular beds successful the quality body.

'If the acute depletion of an e-cigarette tin person an effect that is instantly manifested astatine the level of the vessels, it is conceivable that the chronic usage tin origin vascular disease.'

Over time, determination are concerns these effects could pb to vascular dementia, erstwhile humor vessels successful the encephalon are damaged, reducing the travel of oxygen and nutrients to the brain.

It could besides pb to strokes, humor clots and coronary artery disease.
