Base Effect on Nicotine Delivery

[SnakeFarm]

My (admittedly short) experience with PG/VG base seems to indicate that PG based liquids deliver more nicotine. I have pretty much settled in to 100% VG at 30 mg, but I have several bottles of older PG based liquids at 24 mg. The 24 mg liquids seem to get me to satiation MUCH quicker. If I continue to vape after that point, I actually experience the old nausea I've associated with acute nicotine overdose. Conversely, the 100% VG stuff seems to take twice as long (even at 30mg) and I never become nauseated, even if I chain-vape it all day long.

Of course, there is the distinct possibility that I'm all wet.

Just wondering if any of you experienced vapers out there have any thoughts on this.

Well, the VG-based juice seems less satisfying, but I always marked it up to less throat hit. Don't know about absorption rates between the two.

Sent from my easy chair using brainwaves.

This is probably true, imo.

It's that the nicotine is dissolved in droplets of the base and that VG is more slowly absorbed, so it evens out the delivery.

To feel the hit, PG; for more even dosing, VG.

I like to mix my pg and vg to 80 % pg / 20 % vg for cartomizers and go 50/50 for tanks. I am sure nicotine delivery though will all even out in end.

That's another thing I've noticed on the PG/VG front. High VG seems to perform better in a tank at first, but the carto seems to start flooding earlier than with PG. It may have more to do with the way I'm slotting them, but after about a month and five or six cartos, it seems more related to the base. Of course there are so many variables it's hard to tell for sure.

There has been nothing conclusive about the absorption rate of nicotine in any base. Any difference you have may be anecdotal.

Im not sure about absorption rates or any of that, but I do notice that I can have 2 clearomizers, 1 full of vg based liquid and 1 full of pg based liquid. If I take 10 big hits off of each one the pg clearomizer will be more empty than the vg. It just seems to me that pg vaporizes at a quicker rate possibly giving the illusion that its stronger when in fact you've just had more quantity..

 

[fray]

Perhaps the pg wicks better allowing or more juice to reach the coil to be vaporized

To know for sure you would have to test for nicotine levels in the blood after inhaling liquid composed of each base.

Boiling point
Propylene glycol = 368F
Glycerin = 554F

Glyerin is also much thicker than pg. In fact pure glycerin would be almost as thick as jelly. It sold diluted with water so it to make ite pourable.

 

[jamesthompson]

Yes i know I hate working with VG it is so damn thick!

Same here. I was happy with 18mg in 70/30 PG/VG but I'm happy with 24 mg VG.
