You seemed to rule out the possibility that no acrolein is produced and I'm not sure why. The lab reports published recently on the vapour by Intellicig showed no signs of acrolein and you seem to either ignore this or discredit it.
I do agree that it is in everyones best interest to find out if there is a problem, but you seem to draw conclusions (read about 10 posts back) that are not supported by the evidence.
I have no idea who you are implicating in an undercover attempt but that conspiracy nonsense really has no place in rational debate.
1) Acrolein will be produced when VG is heated to its boiling point (that much is fact); little might be in the vapor if it reacts/degrades immediately on the coil. A detectable level of acrolein might only occur when the coil is running dry, the time when the bad smell is noticed.
In fact, when evidence arises pointing to no acrolein I always feel that is good news, say so, and still hope that will be the case somehow.
2) 'conspircy nonsense' - not me who introduced this. In countering conspiracy nonsense aimed at me i pointed out the obvious flaw: there's no point scaring a few peple with non-fact, but there could be reason to detract from uncovering something that could be corrected quite easily and would harm vaping considerably if left in place. This is rational. I don't see an undercover attempt, I see only ignorance and well-meaning posts, but my point is that a shill, if there was one, would want to keep the issue hidden and uncorrected for now for use in destroying vaping at a later date.
