CDC says stop vaping as mystery lung condition spreads

I don't have time to thoroughly examine your references right now, but I can tell you off the bat that the third study is very poor - they measured vapor samples at 500°F and 600°F, which is substantially in excess of normal vaping temperatures and would almost certainly produce an acrid, foul-tasting vapor. The presence of CO in the vapor samples clearly indicates oxidation rather than vaporisation. Of course you get lots of nasty byproducts if you burn the liquid.

I think what's going on there is that one of the e-cigs they used had a configurable temperature (200-600 °F). I'll give them the benefit of the doubt and assume that they selected a reasonable one (they don't appear to specify in the methods).

Separately, there's the GC-MS machine - oven (30 - 220 °C ramp) and inlet (320 °C). This shouldn't be (much of) an issue though, as an inert carrier gas is used. Plus you always have controls, so if the GC-MS itself is tearing things apart it should hopefully be obvious.

That being said, I didn't see anything particularly concerning listed in their results (relative to recreational cigarette or alcohol consumption).

Recreational cigarette smoking? I've never met such a creature. Your either hooked or your not.

In the medical literature there is a classification referred to as a "chipper" who generally smokes only 1 or 2 cigarettes a week on average. Humans are many and varied.
