Nicotine math help?

[brokesd]

I'm trying to figure out how many drags on my e-cig = how many drags on an analog (my old favorite deathstick was Pall Mall Menthol)

1 Pall Mall Menthol (about 12 drags) = 1.1mg of nic
1.1 divided by 12 equals 0.09mg of nic per drag

Now onto the fun part...

1mL of e-liquid = approx. 28 drops

(I'm not sure how many drags = one drop of e-liquid. 4 or 5 is my guess. I'll just say 4 cause I'm a ferocious inhaler If I'm way off on this estimate, please let me know.)

28 drops x 4 drags per drop = 112 drags per mL

This is where I get confused...

If 1mL of juice equals 112 drags, and there's 24mg per mL, then...

112 / 24 = 4.66

4.66mg of nicotine per drag?? That's like 4 cigarettes worth of nicotine!

I'm not good at this calculating stuff, so I'm probably way off. Could someone help me figure this out? I'd like to be vaping the same amount of nicotine (or less) that I was consuming with analogs, and if I could convert that to how many e-cig drags approximately equal one analog, that would be great.

I am not really sure but something tells me the strength of nicotine is the consistency of the smoke/vapor.
I dont think it is divided and evenly distributed..
I could be wrong..

You're slightly upsidedown, mg per drag using your numbers would be

24mg / 112 puffs =~ 0.21428 mg in each puff, but if you search around the threads regarding
how much nic is actually absored when vaping, I believe the generally accepted
number is about 40% of what an analog provides. So the final number would be
(drum roll...)

0.085714 mg per puff???

Minus the > 4000 other chemicals you inhale from analogs, find a nic level you
feel good at, if it keeps you off analogs, worry about the nic level later, you can always
cut back. Or heaven forbid vape less....

But does he still get Diacetyl?

Interesting idea. I wonder if nicotine settles to the top or bottom of the bottle...? Oh well. I shake it up either way. It makes me feel like a chef

Thank you, just what I was looking for! I'm not too worried about nic levels, but I do like to know what I'm inhaling. As for vaping less... no thank you

Nom nom

Hmm.. But that figure runs very close to his earlier estimate regarding mgs of nicotine per drag on an analog. More to the point, is it most people's perception that vaping an e-liquid that aproximates one's previous smoking habits (ie, vaping an e-liquid with a nicotine concentration that's close to the average amount you would previously inhale with analogs) that the actual nicotine intake is reduced by 40%, all else being equal?

That's actually pretty good, but is it just a perception or has anyone actually done any testing to determine this? I'm pretty sure the actual vaporizing of nicotine on e-cigs works differently than the combustion on analogs and it's not a stretch to think that the lungs might react differently too. Temperature could also be a factor.

Anyway, I'm just curious 'cause I get the feeling one can overdo the nicotine intake when vaping pretty easily, and nicotine by itself is a pretty nasty drug. I'm not shrugging away the fact that vaping dispenses with all those other thousands of nasty substances you'd inhale with an analog, but my long-term goal with vaping is to do away with nicotine, period, so I'm curious about this specific point.

If anyone could point me to a study regarding this matter I would appreciate it.

The commenter above is correct - you have to divide the 24mg per ml by puffs per ml to get nic per puff.

Only you would know how many puffs you can get out of a drop. Sort of hard to tell. I tell more by day - I had a 10ml bottle of juice and noticed when it was 1/3 empty, 1/2 empty etc. (like 1/2 empty meant I had vaped 5ml since I started the bottle days before)

Hmm math`s fine.
But it's kinda impossible to know how much nicotine you get per drag ,since nicotine gets almost destroyed from heat-fire.
So you need chemistry too.
Also keep in mind that cigarette smoke and vapor ,give different mixing of substances that allows different nicotine absorption from body.
For example ,recently i read a research that shown that an e-cig could eliminate the nicotine carvings but the nicotine level in blood were almost in to zero.

@Pilton: that was pretty much what I was thinking. Can you remember where you read about that research, maybe provide a link?

There are some blog entries on ECF done by a PHD chemist with pointers to studies, but I don't have it bookmarked.....
search ECF for nic and amounts and percent ????

I get 3 drags per drop when dragging for about 6 to 7 seconds.

It would be quicker to search at Google to find anything here. You can also fine tune your Google search by adding the following on the search line:

site:www.e-cigarette-forum.com

The following example at Google found 120 results:

Or you can narrow down the search and find 15 results:

Duh! thanks deback, was a bit lazy there.
