ANOTHER study finds popular brand of e-cigarettes cause DNA damage in lungs

Vaping for just one month leads to DNA damage that is comparable to smoking tobacco, another damning study of e-cigarettes suggests.

Researchers at McGill University in Montreal, Canada, exposed mice to the equivalent of 60 puffs of a mango-flavored Juul device per day for four weeks.

The rodents sufferedcellular and molecular changes that have been linked to the formation of cancer in traditional cigarette smokers.

America is currently in the grips of a vaping epidemic among children that has been blamed on child-friendly flavoring and glitzy shop window displays.

At least2.6million American children 11 to 18 years old usee-cigarettes, official figures show, and the number is rising.

In the latest study, scientists exposed mice to air from a Juul device, which contained nicotine.

A third of the mice were blasted with 60-Juul puffs a day, administered in three 20-minute sessions with a three-hour gap between each.
