Does the Pg:Vg ratio affect nicotine absorption?

[desk1%]

I noticed after switching to 50/50 that I got my nic buzz on quicker. I don't know if it's just how long I can internalized the vape or if there's really a better nic absorption of Vg. Are there any studies? Anyone else have a similar experience?

Oh yeah. I don't know of any studies about it, but from my own experience, VG definitely gives a harder nic hit. VG also makes me feel congested, though, so I mainly stick to PG. Maybe VG lingers in the airways longer and has more time to be absorbed?

I haven't noticed any difference between 70/30 and 50/50 but hearing your experience it might make sense since more VG = more vapor. Then again, your body's absorption rate wouldn't change which takes place in the mouth first. Do you hold it in your mouth longer with more VG? I ask that because inhaling VG is tuff at least for me because the vapor is so thick. It even made my chest feel heavy back when I was lung inhaling which I don't do anymore.

From my experience I get the same results. VG does seem to deliver more nicotine. Could be due to the thicker viscosity, and or thicker vapor.

I don't think I ever held VG vapor in my mouth longer than PG vapor. I vape the same way regardless of the VG ratio of the liquid. I bet you're right and it's just a factor of the thicker vapor VG produces. It makes sense that more vapor per puff would carry more nicotine per puff.

I speculate that since VG bonds better with both lipids and water that there may be a more affirmative transfer to the blood vessels. Back when I was in the the ......... agricultural, processing and distribution industry I found that I could make a much more effective and fast acting tincture using VG and cold pressed oil. The initial version I made was cold pressed oil, grain alcohol and PG and the effects seemed to be much slower in action. I'd been out of that industry for some time by the time I got into PV 8 months back and this is vaporizing that was ingestion. I'm happy to hear that other folks have the same experience with higher VG it seems to justify my insanity a bit.
