Thank you very much for sharing!
@mannikon It's quite controversial, but it's all about the amount it's in. Most of the flavours contain it in (really) minor amount anyway including in the reformulated "non-containing" flavours (Source:

I'm just getting more seriously into DIYing so unfortunately I don't know much information about the scientific data on amounts and etc. Personally for now I trust the big flavour manufactures that do independent tests on their flavours that they know are used for vaping, and only use the reformulated ones and the ones the flavour manufactures give a green light themselves. In the mean time I'll keep educating myself about safe levels and etc. and avoid adding more AP myself until I know more.
