Speaking of photo's how did they get a picture of Sun's e-cig stash?
Good article, I do get sick of hearing/reading how the FDA found bad stuff in the tests they did. I still don't really believe their results.
I do believe FDA "detected" TSNAs in some of the cartridges, because other labs have found tiny amounts of TSNAs in the liquid. The point is that a toxicology report needs to specify quantities. There are traces of toxins in everything. Any substance, even water, can be toxic in large enough quantities.
We learned from the Health New Zealand testing that the TSNAs in the 16 mg. cartridge of Ruyan brand contains only 8 nanograms per gram of TSNAs. A comment below Table 2.2 on page 7 says that 8 ng. is equal to the amount in a medicinal nicotine patch.

Knowing that, and learning that there are 11,190 ng in a single Marlboro, puts the entire issue in perspective. E-cigarette liquid is no more carcinogenic than FDA-approved NRT products and is thousands of times less carcinogenic than
tobacco cigarettes.
And to add another level of safety to the picture, keep in mind that users don't drink the liquid. They vaporize it. No lab, including the FDA, has found carcinogenic substances in the vapor.
Whether or not FDA did find 1% diethylene glycol in one of the 18 cartridges tested is beside the point. It doesn't prove the products present any danger to users.
Since the toxic level of DEG is 1 ml per kilogram of body weight, at 1% it would take 100 cartridges to equal 1 ml of DEG. 1 pound = 0.45 kilos. So, to calculate how many cartridges it would take to achieve DEG toxic level for your body, multiply your weight in pounds by 45.
For example, a 150 pound person would need to vaporize 6750 cartridges in a single day to reach toxic levels of DEG. Most folks use between 1/2 and 3 cartrdiges.
