actually, low to non detectable on Diacetyl but through the roof on MANY for Acetylpropionyl.... like so high, Nicoticket is reformulating their liquids to lower the levels... so, no, just becuase they post the levels, i dont think that makes them responsible. It makes them transparent about putting harmful ingredients in their product though.... the responsible thing to do would be to dramatically lower those levels or go a step further and remove them altogether.... that is where the industry is headed anyway and once FDA steps in, they will all have to do it anyway
