Thank you for posting this link. Very interesting to read.
The antifreeze scare is based on the finding of a bit of diethylene glycol in one of the cartridges tested by the FDA.
While important to take note of since is should NOT be in there, it was found in only one cartridge out of the 18 tested.
It was NOT found in the any of the njoy cartridges tested, only in one of the Smoking Everywhere cartridges.
And even knowing that, you should also know that the amount of diethylene glycol that was found in that one Smoking Everywhere cartridge (approximately 1% according to the test results) is not particularly harmful and would require sucking down around 600 hundred cartridges in one day to get near a toxic level.
Also of note is that diethylene glycol is also in cigarettes.
And the FDA allows amounts of less that 0.1% to be present in any products that contain propylene glycol.
Yeah, that is not the best news, but not the worst news either.
And yes, again, that diethylene glycol should not be in there no matter how little there was.
But the most important thing to know?

No other tests have ever found diethylene glycol in any electronic cigarette liquid.
And no test, including the FDA test in question, has EVER found DEG in the vapor produced.
