Math masters needed, nicotine eliquid vs analogs

[makdevo]

I posted this in the general forum to get more exposure. Maybe we can make a sticky if there is enough intrest.

Link to eliquid study
http://healthnz.co.nz/RuyanCartridgeReport21-Oct-08.pdf

On the second to last page, table 1.2 shows nicoting strength as a liquid percentage, 16mg = 1.6%, 11mg =1.1% and so on. I suppose the same is true for 24mg and 36mg, 2.4% and 3.6%.

To me this looks like 10ml 24mg strength of eliquid would contain 2.4% nicotine. I know absorbation must be factored and that is covered in another study (link posted on this forum somewhere). I have the pdf but can't upload it, too big.

Now for my question.

Lets assume 1 analog is 2mg of nicotine. Lets assume that I smoke 20 analogs a day, that means I am taking in 40mg of nicotine per day.

Now I want to match that with eliquid, how much 24mg strength eliquid do I need to vape in one day? (ml/day)

Just simple intake calcs is all I'm looking for. Then I can factor in absorbtion, which by the way is very low according to the study I mentioned.

10 ml of 24 would be 2.4% x 10

1.5 mls would be 36mg but the absorption factor is unclear at best. I would recommend vaping what makes u comfortable,, but that's just me.

signs are starting to show that you couldn't intake enough to match cigs.

Thanks for the post happy. I can and do vape what makes me happy. I am trying to get a dialog going to answer a question that shows up on this forum many times.

Some people would like to have a guage. True numbers can be a tool.

I'm gonna try this but would like correction if wrong, as this is how I understand it.

To know what nic content you need you have to figure out how many ml of liquid you are vaping a day. If you Vape 1 ml a day then you would need 40mg per ml to get your 40 mg of nic in a day, or if you go through 3 ml of juice a day the you would need something in the range 13.3 mg per ml juice.

Think of it like this if you had a 3ml dropper bottle and you put in 1 ml of 24 mg nic juice and 1 ml of VG and 1 ml of PG, you would have a total of 3 ML of juice mix with a content of 8 mg per ml. If you had a 10 ML bottle and you put in 5 ML of 24mg nic juice and 5 ML of cut (VP or PG or both) then you have a total of 10ML of mix with a total of (24 * 5) 120mg of nic, so each 1 ML of mix would contain 12 mg of nic.

I think you got it, but if not I hope someone corrects you too.

So if you're right, then you have to divide that nicotine content by a factor of 10 supposedly.
That's due to the NZ study that we are only absorbing 1/10th the nicotine we do from a cigarette.

look i don't want to come off as being unhelpful here, but there are LOTS of posts about this exact information, it has been gone over and over. save yourself some headache from doing the math and look for those

I came up with a rough equation that got lambasted in a prior thread, but it is still a solid approximation IMO:

OK, so my rough equation for selecting juice density is:

(mg nicotine in your analog) * 10

BTW, the 10 comes the rough equivalent of .1 ml / cig, which of course depends on the hardware being used and its consumption rate on average.

Now for my question.

Lets assume 1 analog is 2mg of nicotine. Lets assume that I smoke 20 analogs a day, that means I am taking in 40mg of nicotine per day.

Now I want to match that with eliquid, how much 24mg strength eliquid do I need to vape in one day? (ml/day)

Just simple intake calcs is all I'm looking for. Then I can factor in absorbtion, which by the way is very low according to the study I mentioned.

# mg per day analog / # mg per ml in the juice = # ml of juice

So, 40mg / 24mg per ml = 1.67ml of 24mg juice.


Since I used to smoke three packs of analogs a day, then I would need 1.67ml x 3; or 5ml of 24mg juice a day. And this is precisely what I vape.

The NZ study and another one with the Cancer Institue going on right now is using 16mg/ml density. It is used as a standard, as per my own concept, BTW. However absorbtion levels generate in curves, not linear so would not be accurate to just multiplyX2 for example. I just did a urine test that uses the by-product of nicotine Cotinine as the testing standard, and in my particular case using PV and 24mg/ml juice my cotinine level was at 200-500 ng / ml. Cigarette smoking as I can find for cotinine levels would have generated 1000-5000 ng / ml in cotinine. Just for example. To my limited ability, the NZ test correlated pretty much with my own personal findings. I will do another in a few days and post those results, also, for either discrepancy or verification. (I hope to verify, since this level of cotinine is about 1/10th that of my smoking days!)

Please do searches on the FORUM for more information, this is a link to the testing I did. Others have tested, with different results.
