EcigChina.Com,Fuyan,Ruyan,Electronic Cigarette,E-Cigarette,China Wholesale Retail, dropship - Density of Nicotine

Text from link copied below:

"0.1ml E-Liquid ≈ 1 Cigarette:
Normally, a cigarette needs to have about 12-15 puffs to finish it, while 0.1 ml of E-Liquid needs to have about 12-15 puffs to finish it also, so that 0.1 ml of E-Liquid is equivalent to a cigarette normally.
We define the density of nicotine inside E-Liquid as the following:
- for the Extra High density of nicotine, there is 24 mg of nicotine inside the E-Liquid,
- for the High density of nicotine, there is 16 mg of nicotine inside the E-Liquid,
- for the Medium density of nicotine, there is 11 mg nicotine inside the E-Liquid,
- for the Low density of nicotine, there is 6 mg nicotine inside the E-Liquid,
- for the Non density of nicotine, there is no nicotine at all inside the E-Liquid.

Nicotine per puff for Cigarette:
The nicotine in a cigarette is variable from 0.6 mg to 2.4 mg. A cigarette needs to have 15 puffs to finish it normally, so that the nicotine per puff for a cigarette is the followings:
- for the cigarette with 1.0 mg of nicotine: 0.6 / 15 = 0.040 mg/puff,
- for the cigarette with 1.8 mg of nicotine: 2.4 / 15 = 0.160 mg/puff.

Nicotine per puff for 0.1 ml of E-Liquid:
Therefore, according to the nicotine density inside a cigarette, we can have the Equivalent Nicotine Density inside 0.1 ml of E-Liquid with the deferent density of nicotine as the followings:
- for the Extra High density of nicotine: 2.4 / 15 = 0.160 mg/puff,
- for the High density of nicotine: 1.6 / 15 = 0.107 mg/puff,
- for the Medium density of nicotine: 1.1 / 15 = 0.073 mg/puff,
- for the Low density of nicotine: 0.6 / 15 = 0.040 mg/puff,
- for the Non density of nicotine: 0 mg/puff.

There are different capacity of E-Liquid inside of the E-Cartridge for the different E-CIG models, so that the the E-Cartridges are equivalent to the different numbers of cigarettes normally."

This is where I get lost:
- for the cigarette with 1.0 mg of nicotine: 0.6 / 15 = 0.040 mg/puff,
- for the cigarette with 1.8 mg of nicotine: 2.4 / 15 = 0.160 mg/puff.

Why aren't they using 1.0mg instead of 0.6mg and
Same for the 1.8 vs. 2.4

I am so lost...in the math at this step, I don't understand why they are using the numbers that they are using.

Well spotted. The logic makes sense but the actual figures used don't.

If you smoked a 1mg cig for 15 puffs it would be 1/15=0.07mg per puff.

There aren't many cigs around that give over 1.4mg nowadays, 1mg is standard strength.

Kate.. thanks for taking the time with that one.. I was in Mathletes growing up and I am good with numbers.. but have not been awake long enough to help with this one

LOL!

Thanks, Kate! I'm glad I'm not nuts. I kept going over and over that part to figure out why they were using those numbers and I couldn't for the life of me figure it out. So glad I can fix my printout and have a reference.

BTW. If anyone wants to check their analog cigarette nicotine content out you can go to this website and look your brand up for tar, nicotine, and carbon monoxide content:

What this actually says is that if there are 15 puffs in a cig and if there are 15 puffs per 0.1ml of eliquid then 11mg eliquid has the same nicotine content as a 1mg cig.

They haven't listed the nicotine levels of eliquid correctly either, they say 2.4mg when they mean 24mg.

Using 0.1ml as a measurement to compare with a cig is interesting. If there are 20 drops in 1ml that means that 2 drops = 0.1ml. 2 drops per cig.

Not everyone gets 15 puffs from a cig or from 2 drops of eliquid but it's the most logical formula I've seen yet.

What she said

My maths is execrable.
