Vapers around the world can breathe easy knowing that E-cigarettes are not harmful, according to new research.
A leading vape brand carried out the two year, 200 person study that found the tobacco alternative does not damage the heart or lungs or cause any health problems.
It backs claims that the smoking devices are a safer option than cigarettes used by an estimated three million Britons, say scientists.
The volunteers were monitored for illness, had their lung function examined and had exposure to nicotine measured.
They also underwent electrocardiograms that monitor heart rate.

Lead author Tanvir Walele, director of scientific affairs at Amsterdam based Fontem Ventures which makes e-cig brand blu, said: "This study shows after two years of continual e-cigarette use, there were no signs of serious health complications in smokers."
The 24 month clinical trial reported in Regulatory Toxicology and Pharmacology showed smokers who used vaping products suffered no harm.
No serious safety concerns were recorded or clinically relevant findings observed in all medically-defined safety criteria.
Incredibly, the use of the vaping products actually revealed a reduction in nicotine withdrawal symptoms.
It also reduced participants exposure to cigarette smoke constituents, and there was no increase in their body weight.
Mr Walele: "Clinical data over a two year period gives us a much clearer picture about longer term vaping, and the potential implications for the health of smokers, so they can make an informed decision."
He said it follows a scientific review last year that found smokers who used e-cigs in the short to medium term - for two years or less - had no increased health risks compared to smokers who did not use them.
They could also help conentional cigarette smokers reduce or quit their habit. But that team said there is just a small number of published clinical studies currently available, and more research is needed.
No adverse health impacts from long term vaping -- Study
24-month clinical trial shows no negative health impact on smokers who used vaping products, and no increase in body weight
Amsterdam, Netherlands, 17th January 2018 - A new peer-reviewed clinical trial to be published in the February edition of Regulatory Toxicology and Pharmacology shows that regular use of e-cigarettes does not have any negative health impact on smokers.
The study, "Evaluation of the Safety Profile of an Electronic Vapour Product Used for Two Years by Smokers in a Real-life Setting", examined 209 volunteer smokers who used a typical closed-system e-cigarette for 24 months while researchers monitored for adverse events, as well as lung function, electrocardiogram results, and exposure to nicotine and tobacco constituents.
"This study shows that after two years of continual e-cigarette use, there were no signs of serious health complications in smokers." said Tanvir Walele, Director of Scientific Affairs at Fontem Ventures, the owner of e-cigarette brand blu.
During the trial, no serious safety concerns were recorded among the participants and no clinically relevant findings were observed in all other medically-defined safety criteria. Further, the use of the vaping products was associated with a reduction in nicotine withdrawal symptoms, reduced exposure to cigarette smoke constituents, and no increase in body weight.
"Clinical data over a two-year period gives us a much clearer picture about longer term vaping, and the potential implications for the health of smokers, so they can make an informed decision." said Walele.
A recently updated Cochrane Review1, whilst acknowledging the small number of published clinical studies currently available, reached a similar conclusion to this study: that e-cigarettes with nicotine can help smokers to reduce or replace smoking with no increased health risks associated with short- to mid-term (up to two years) use.
"Governments and policy-makers should ensure that regulatory frameworks reflect this emerging scientific consensus, as more long term research demonstrates the safety profile of e-cigarettes," said Walele. "This research suggests we need e-cigarette regulation that is not modelled on tobacco product regulation, but encourages innovation and compliance with robust product quality, manufacturing and safety standards."
