Ok you guys win lol. I've been trying exhaling through both my nose and mouth and I do agree I taste more flavor problem is my nose runs instantly. Right now I'm using 100% VG
Please note I'm not an "expert" here
So your nose runs when you exhale vapor through it. While personally I've never had that problem without actually being sick (I caught the flu from a co-worker last year, first time I've been sick in nearly two years actually aside from when someone sneaks in some dairy on me but that effects a different anatomical system,
) or it being allergy season. (Vaping I think has actually made my seasonal allergies worse as my air passages and sinuses are no longer clogged with tar.) I can only think of a few factors that could be at play here:
1. Your nicotine may be at too high a level. If you do not inhale into your lungs your vapor you may not notice that the nic level is too high for you. Myself, I know when I need to raise or lower nic level based on lung/chest feel. But I almost always inhale my vapor into my lungs.
2. PG may be aggravating your mucus membranes. I know you say you're using 100%VG but I can assure you that no juice is 100%VG. Even if you are using a VG nic solution and a VG base, even at USP Pharmaceutical grade there can be as much as 0.3% "other compounds". Probably water, in this particular case. However, if you are using a flavoring of any kind, it likely has PG, or alcohol in it, and PG is more common. I used to cut my max VG mixes with distilled water, this was back before sub-ohming and dual coils and so on so thicker juices tended to be a problem for some heads and cartomizers, but found the water would actually irritate my throat.
3. The flavoring compounds themselves may irritate your mucus membranes. I find some juices cause me to have a sore throat even though they are 60/40 pg/vg or even higher on the VG ratio.
4. You may be sensitive to the VG. I know it sounds strange, but I've heard of others complaining of a sensitivity to VG and thus prefer higher PG blends. (though it seems VG is a necessary component in juice for vapor production.) I would say that these people are likely encountering juices made with food grade VG (which contains more impurities than pharmaceutical grade). That said, I've noticed that I sometimes "feel heaviness" in my lungs/chest when I vape max VG juices in particularly humid environments. And I live in Florida so that is
basically anywhere outside during the summer months, which are March thru to October.
