Diacetyl found up north in analysed e liquid  No clip link yet, but it gives a horrendous impression.

E-cigarette liquid bought on Tyneside contained a potentially harmful chemical, a BBC investigation found.
Inside Out bought four liquid refills and sent them to a laboratory for testing. Three were clear but a fourth contained a chemical called diacetyl.
It is used as a flavouring in foods and experts said while it was safe to eat it was not safe to inhale and had been linked to a serious lung condition.

VIP, which distributed the refill, said it had been withdrawn from sale.
The four samples were bought in shops and markets and were sent for testing at a food control laboratory in Leeds.
The refill found to contain diacetyl was VIP's butterscotch flavour and was bought at its shop at the Metrocentre, in Gateshead.


See more on this story on Inside Out in the North East and Cumbria, Monday 1 September, 19:30 BBC One.

Yup and it was only a matter of time before the media picked up on diacetyl and it's links to possible health issues

Some info from reddit

"This post is intended to be stickied and work as a caution about the flavouring that might be used in some e-liquids and flavourings called Diacetyl.

Diacetyl is a butter flavoring used in some food products like butter, butterscotch, butter flavoured popcorn and some alcoholic beverages. It has also found it's way into the ingredients of some e-lquids. The FDA and the EU regard it as GRAS (Generally recognized as safe) and permit it for consumption though it has come to light it might not be suitable for inhaling:

The United States National Institute for Occupational Safety and Health has suggested that diacetyl, when used in artificial butter flavoring (as used in many consumer foods), may be hazardous when heated and inhaled over a long period.

Workers in several factories that manufacture artificial butter flavoring have been diagnosed with bronchiolitis obliterans, a rare and serious disease of the lungs. The cases found have been mainly in young, healthy, non-smoking males. There are no known cures for bronchiolitis obliterans except for lung transplantation.

While several authorities have called the disease "Popcorn Worker's Lung," a more accurate term suggested by other doctors may be more appropriate, since the disease can occur in any industry working with diacetyl: diacetyl-induced bronchiolitis obliterans.

After the workers filed a lawsuit against the manufacturers, the United States Environmental Protection Agency began an investigation into the chemical properties of microwave popcorn butter flavoring. In March 2004, former microwave popcorn plant employee Eric Peoples, of Joplin, Missouri, was awarded $20 million for permanent lung-injuries sustained while on the job. On July 19, 2005, jurors awarded $2.7 million to another popcorn plant worker in Missouri for his claim of diacetyl-induced respiratory problems

Dr. Cecile Rose, pulmonary specialist at Denver's National Jewish Medical and Research Center, in a letter, warned federal agencies or regulators that consumers, not just factory workers, are in danger of contracting bronchiolitis obliterans from fumes produced by microwaving popcorn containing diacetyl. David Michaels of the George Washington University School of Public Health first published Rose's letter on his blog. However, the only sample data known-to-date is the case where a consumer, who ate at least two bags of buttery microwave popcorn daily for 10 years, became diagnosed with the same disease affecting workers exposed to the substance, bronchiolitis obliterans. His lung problems were linked to breathing the vapors; although rare, the reported man's kitchen also had diacetyl levels comparable to those in popcorn plants." 

It appears to be used for milky, creamy type flavours, like butterscotch etc. It`s safe to eat but not to vape it.

This isn`t actually new news, it`s a subject that has been around for a few years. Worth checking with the makers if it contains it  Greg.  Like I said, it`s safe to eat but not to vape.

Yes I've heard of it before robby, I guess posts like this just make you consider it again

What worries me is that the vaping community has known about diacetyl for quite some time and most e-juice producers had eliminated the ingredients that could contain it.
A company the size of VIP should've been well aware and dealt with this months ago.
No-one can really argue that some form of regulation is going to be needed to make sure that juice makers are making safe products.
Clearly even the bigger boys in the vaping game can't really be trusted completely to regulate themselves

I`m glad my all day vape is Hangsen Virginia,

"Diacetyl: Diacetyl is used in many food products to create an artificial creamy, buttery flavour. Diacetyl can be harmful if inhaled. We ensure non of our hangsen e-Liquids contain the flavouring ingredient diacetyl.
Acetoin: Acetoin may react when mixed with other chemicals and may create traces of Diacetyl. Due to this finding, we do not use any flavoring ingredients containing Acetoin. Our hangsen e-Liquids are water soluble and do not contain any oil based flavorings which can be harmful if inhaled."

It also raises the possible increased danger if you are vaping clouds. Surely the danger from diacetyl must be increased if you are using an eliquid that contains it and covering your lung surface in it by so much vapour.
