E-cigarettes contain up to 10 times the level of cancer-causing agents in regular tobacco, Japanese scientists said Thursday, the latest blow to an invention once heralded as less harmful than smoking.
The electronic devices -- increasingly popular around the world, particularly among young people -- function by heating flavoured liquid, which often contains nicotine nike air vapormax plus pas cher , into a vapour that is inhaled, much like traditional cigarettes but without the smoke.
Researchers commissioned by Japan's Health Ministry found carcinogens such as formaldehyde and acetaldehyde in vapour produced by several types of e-cigarette liquid, a health ministry official told AFP.
Formaldehyde -- a substance found in building materials and embalming fluids -- was present at much higher levels than carcinogens found in the smoke from regular cigarettes, the official said.
"In one brand of e-cigarette the team found more than 10 times the level of carcinogens contained in one regular cigarette," said researcher Naoki Kunugita, adding that the amount of formaldehyde detected varied through the course of analysis.
"Especially when the... wire (which vaporises the liquid) gets overheated nike air vapormax flyknit pas cher , higher amounts of those harmful substances seemed to be produced."
Kunugita and his team at the National Institute of Public Health, who submitted their report to the ministry on Thursday, analysed several cartridges of e-cigarette fluid using a machine that "inhaled" 10 sets of 15 puffs.
One brand, the name of which was not revealed, showed a more than 10-fold level of formaldehyde on nine out of every 10 sets.
Another brand showed similar levels on several sets, but was not consistently that high.
Kunugita said the research showed e-cigarettes are not the harmless products many people assume them to be.
"We need to be aware that some makers are selling such products for dual use (with tobacco) or as a gateway for young people" to start a smoking habit nike air vapormax femme pas cher , he warned.
In common with many jurisdictions, Japan does not regulate non-nicotine e-cigarettes.
- 'Serious threat' -
Nicotine e-cigarettes, or so-called Electronic Nicotine Delivery System (ENDS), are subjected to the country's pharmaceutical laws, but they can be bought easily on the Internet, although they are not readily available in shops as they are in some Western countries.
"You call them e-cigarettes nike air vapormax homme pas cher , but they are products totally different from regular tobacco," the ministry official said.
"The government is now studying the possible risks associated with them, with view to looking at how they should be regulated."
In August, the World Health Organisation called on governments to ban the sale of e-cigarettes to minors, warning they pose a "serious threat" to unborn babies and young people.
Despite scant research on their effects, the WHO said there was enough evidence "to caution children and adolescents nike air max 270 off white pas cher , pregnant women, and women of reproductive age" about e-cigarette use, due to the "potential for foetal and adolescent nicotine exposure (having) long-term consequences for brain development".
The UN health body also said they should be banned from indoor public spaces.
US health authorities said earlier this year that the number of young people there who have tried e-cigarettes tripled from 2011 to 2013.
More than a quarter of a million young people who had never smoked a cigarette used e-cigarettes last year, the US Centers for Disease Control and Prevention said.
Supporters of e-cigarettes say the devices are a safer alternative to traditional tobacco, whose bouquet of toxic chemicals and gases can cause cancer, heart disease and strokes -- among the leading causes of death in many countries.
But opponents say the devices have only been around for a few years nike air max 270 just do it pas cher , and the long-term health impact from inhaling their industrial vapour is unclear.
Big tobacco companies are snapping up producers of e-cigarettes, wary of missing out on a snowballing global market worth about $3 billion.
Earlier this month, Oxford Dictionaries picked "vape"-- the act of smoking an e-cigarette -- as their new word of the year.

MELBOURNE, July 30 (Xinhua) -- The head of Australia's National Basketball League (NBL) has held talks with National Basketball Association (NBA) officials about bringing the world's best basketballers to Melbourne for an Australian series.
Larry Kestelman, who is the league's executive director and co-owner of NBL club Melbourne United, said he had a vision for short series to be played in Victoria's capital in the NBA offseason nike air max 270 premium pas cher , most likely as early as 2017.
""We've opened a constructive dialogue with the NBA ... there is no reason at all they can't come here,"" Kestelman told News Limited on Thursday.
Following the raging success of football's International Champions Cup (ICC) last week - which drew crowds of 99,000, 40,000 and 80,000 to friendly matches between Real Madrid nike air max 270 flyknit pas cher , Manchester City and Roma at the Melbourne Cricket Ground (MCG) - the wealthy businessman is confident the series could attract the same fanfare.
""The sort of interest it would (create) would rival anything, like the recent State of Origin (rugby league match) in Melbourne,"" he said.
Kestelman believes the Australia's strong presence in the world's best basketball competition, with players such as Australian NBA champions Andrew Bogut and Patty Mills, would also provide focal point for the series.
""Any game we can get with an Aussie playing we would love to get,"" he said.
It is unlikely the series would be played as a part of the NBA regular season nike air max 270 femme pas cher , with a ""Best of the NBA"" versus the Boomers - Australia's nati.
