Really any popular name companies, they all seem to have some sort of guidelines including "most" do not use diacetyl. PG/VG are both safer than smoking, as to which is safer is up for debate imo, I am no scientist nor do I try to act as one, but I'd stick with whatever ratio you like the most.
Just switching to vaping, from what we have seen and heard so far is MUCH MUCH better than smoking ciggies.
PG = Propylene Glycol, which typically holds flavor more, typically more Throat hit, less vapor.
VG= Vegetable Glycerin, which is typically less flavor because it carries flavor less, less throat hit, more vapor ( also much thicker, which may be worse for certain setups, also bunks coils quicker.
I suggest just delving deeper into the forums to look up the benefits of either, but as I have said before I firmly "believe" either way your better off than smoking, I think you should just choose what you like the best.
As to which companies have "healthier" ingredients I also believe that is up for debate, I suggest emailing each company that you are interested in and asking what they use in their products if your concerned. OR maybe the have a person on here for their company that you could even PM to ask.
Either way, Good Luck in your searching and Vape On!
