Indoor Air Quality - formaldehyde in ecigs

[clint]

Shouldn't really say, but looking at those figures, and assuming the tests where identical. It appears that the 2 chemicals are coming from the flavouring.
Notice the big jump between the apple and tobacco flavours. And is it plausible to say that the difference between the to apple flavours, could be a difference in flavor strength.
Either way still saver than the alternative.

Something I wonder, and I've said it in another thread, is that different types of juice could make all the difference.

ie different ratios of pg and vg, flavourings vs no flavourings and different nic strengths vs zero nic juice.
