I recently found out im highly allergic to PG(Propylene Glycol) & PEG (Polyethelene Glycol). Now right before i found out from my Allergist about my allergy to PG I had bought over $150 worth of Capella Concentrates all PG base(To answer your question, Yes I don't have any flavoring at the moment that I can use because of this). Now I'm looking to see if anyone has any concentrates that are 100% VG Base and would like to trade me because I can't go on much longer smoking VG & Nicotine, it's killing me(not literally but you know what I mean). If anyone can help/wants to trade me then please hit me up in a private message on here. Thanks
