The e-Liquid Test!?

[Happy Landings]

I have been vaping for a few months now. And I can truly say that it has saved my life by getting analogues out of my life once and for all! It has been a wonderful experieince, and I see why vapers have such passion about it.

But...

I know that the brain is craving nicotine and vaping delivers that to be sure. But has anyone with a chemistry background ever tested eLiquids from several different retailers to see what the actual amounts are in the eLiquids we all buy on a regular basis? We all see our bottles each day that say 18MG or 24MG, PG 70%/VG30% etc etc. But I wonder if most eLiquid makers and retailers actually deliver close to the strengths in nicotine that they are advertising? I wish they would explaoin their quality control and manufacturing procedures to give us consumers more confidence about the contents of what we are vaping.

Just some food for thought...?

I've seen a couple of studies where they did such tests with a couple of vendors, and the nic levels were reasonably close to what they claimed (give or take a couple of mg/ml).

You can test the nic level yourself, too.

I expect the nic levels are real close since that is added separately. I don't trust the PG/VG as much. Some flavorings are PG-based and some water-based and some with other bases, and flavorings sometimes need to be 10-20% of the liquid. And the nicotine can be in PG or VG. So (for example) if the mixing is done in a simplistic manner and the flavoring and nicotine are added to 70pg/30vg then what you end up with is not 70/30. Mixing can either be done with a calculator so the final ratio of the base is 70/30 or done the other way which will change the 70/30 to a somewhat different ratio.

Some vendors have also talked about (and perhaps did, I haven't kept up with it) having independent analysis of their products to prove they are putting in what they say they are.

As for the pg/vg, when I mix my own I make sure to count for the PG in the nic base I use, but the flavoring is going a bit too far for my level of caring. Even if it's off by a couple %, it's not that much to make me care, PG/VG mix is all about what level of throat hit and vapor production (as well as flavor) I'm looking for, the exact numbers are meaningless IMO.
