I'll also note this since some posts said that the all-organic stuff is 100% VG.
Now, before I state anything else, you have to realize this is just MY current thoughts and approach. There's very little data on this long term from a vaping perspective:
There was a thread on here somewhere about someone having issues with vaping and the doctor's consensus was that the vaping and VG was, at least in part, a problem for her. VG is kind of a fat and it can build up in the lung tissue for some people at least. That's not to be fear mongering or anything and I can't say one way or another that it's good or bad. There are others that are sensitive to PG and have to use all VG. Whatayagonnado? I think she had other issues and was using other medications that could have effected it. Far from conclusive.
As for me, I'm cutting down on VG. I was up to 50/50 mixes for a while, but now I'm back to 75 PG 25 VG and will go lower with the VG. That's me. IDK if it makes a difference for anyone else or not. The 50/50 stuff gave me a "heavy" feeling.
So if "all organic" means 100% VG... you'll have to do your own research. I repeat...not conclusive...and not fear mongering. But I am mentioning it due to the 100% VG post in this thread and due to the timing and my current thoughts on the matter.
I'm not scared by PG. OTOH...I may very well use an all-organic flavoring for my DIY juice...but I won't buy pre-mix at 100% VG for my needs since I want 25% or less VG. May even get to 100% PG. IDK.
