E-cigarettes have swept the world over the last few years, presented as the innocuous solution for smokers who want to quit.
It all seemed too good to be true, there had to be a catch.
According to new research by a team at the University of Rochester, the e-cig flavours like cinnamon and vanilla increase the risk of developing life-threatening diseases.
Here’s a discussion about vaping on This Morning:
Not only do e-cigs put an end to breathing the toxic smoke from cigarettes into people's lungs, but they can flavour the vapour they inhale with almost any taste you could think of.
The researchers exposed immune cells to chemicals used in e-cigarette flavouring and found the cells produced substances responsible for inflammation and tissue damage, with many of the chemicals causing significant cell death, reports Science Daily.
In particular it's buttery flavours like cinnamon and vanilla which are the most toxic.
E-cigarette use has increased in recent years as traditional cigarette consumption declined, but this study provides some insight into the harmful effects of this healthier tobacco alternative.
In the US, there are more than 500 brands and nearly 8,000 vaping flavours on the market, according to the American Lung Association.
Senior author Dr Irfan Rahman, of the environmental health sciences centre, said
Currently, these are not regulated and alluring flavour names, such as candy, cake, cinnamon roll and mystery mix, attract young vapers.
Researchers said tighter regulations are necessary to reduce the risk of 'inhalation toxicity' due to exposure to vaping flavouring chemicals.
E-juice bottles must have a descriptive listing of all ingredients. We urge regulatory agencies to act to protect public health.
The new study, published in Frontiers of Physiology, was an investigation into the health effects of flavouring chemicals without nicotine.
They found flavouring chemicals can cause inflammation to monocytes, a type of white blood cell involved in protecting the body against infectious diseases and foreign invaders.
Popular flavours like cotton candy, cinnamon and vanilla were some of the most toxic.
The study also found mixing flavours has a much worse effect than exposure to just one.
