Hi @Nick
If I am not mistaken E Liquid Project made by @KierenD (vape cartel) explicitly states that his juices do not contain acetyl propionyl or diacetyl
Sitting in class the other day...
A chick who is twisping (after seeing me take a small low watt puff) says: "Oh that is the hubbly one. Its only for making lots of smoke. Mine is the one for people who want to quit smoking"
I was quite speechless. Did a little awkward laugh and said "not really"
