nicotine

Does anyone know about the nicotine levels in juice. I mean, when you get a 36mg bottle, exactly how much nicotine is in that bottle? When you get Nicorette for example, there is a precise amount of nicotine in that piece. So 36mg of nicotine in juice means...., 36mg of what initial quantity?
Just like to know.

The M401 holds 1/2ml liquid and is the rough equivalent of 6 cigarettes, based on nicotine content at 18mg/ml. That would mean that your body absorbs 1.5mg of nicotine for each analog you smoke.

As far as I know, there have been no studies done on how much nicotine your body absorbs from vaping.

hey nurd (always wanted to say that)

the 36mg/ml for bottled juice means 36mg of nicotine is each and every ml of the juice. a 10ml bottle has 360mg of nicotine in it. Don't drink this.
36mg/ml strength liquid seems a little strong to most people so I would guess it delivers more that most forms of tobacco. 6mg/ml seems really weak to most folks. Seems like that sets a range for comparison.

Even if we knew the exact amount of nicotine you absorb from both analogs and eCigs, it still wouldn't be an accurate comparison. People vape differently than they smoke. What we need is a poll ... How many packs a day did you smoke pre-eCig, and how many ml of juice to do vape now. I've been wondering this, and plan to pay attention one day soon and figure out just how much juice I go through.

I used to smoke a box of 20 (inhaled) 48 gauge 6 inch hand rolled cigars a week plus about 7 packs week of little cigars to fill in. I now vape about 4 or 5ml of 24mg/ml juice a day. 36mg/ml seems too strong and I can't get a good measurement for the whole day from that strength. There are not enough hours in a day to evaluate 6 to 10mg/ml juice.
Care to do the math on that one?

found this, and I'll tell you that the recommended dosage for the patch just dulled the edge, that's all. 4-5 ml of 24mg/ml juice does it much better. How much is absorbed? have no idea.

..this isn't true for Johnson Creek liquids (just incase that's your preference)

Firhill,
Could you elaborate on this? How does JC measure their liquids? I just figured the MG on the bottle was in per ML just like other eliquids. Is this not the case?

There was a very informative study done by a third party lab in New Zealand for the Ruyan e-Cig. I don't know how many of you have read it.

http://www.innovapor.com/docs/2.pdf

It states in the report that the nicotine in cigarette smoke is 98% absorbed by the user. I thought it also mentioned how much of nicotine is destroyed in real cigarettes due to the heat of combustion, but I must have read it somewhere else as I can't find it in the document.

Quote:

Inhaled nicotine in cigarette smoke is over 98% absorbed, and so the exhaled mist of the e-cigarette is composed of propylene glycol, and probably contains almost no nicotine; and no CO. (see Figure 3.5) Lacking any active ingredient or any gaseous products of combustion, the PG mist or ‘smoke’ is not harmful to bystanders. The ‘smoke’ or mist is not tobacco smoke, and not from combustion – no flame is lit – and is not defined as environmental tobacco smoke. E-cigarette “smoking” would be permitted under New Zealand’s Smoke-free Environments Act 1990.

Side note: It's interesting in the article it mentions the Ruyan as using a piezo element for vaporization. I thought it's been shown they use a heating element like all the other e-cigs.

Thanks Anon, Good point, burning does indeed change the amount of nic absorbed but sadly not enough of the other harmful 4,000 chemical additives.
And here's another thing to add to the mix, because nicotine from eCigs is absorbed more readily (oh, I really like that phrase "more readily absorbed"! I should work for the FDA. lol) because it isn't burned like in analogs, one can also puff without inhaling it and absorb the nicotine through the tongue and mouth. Maybe we should just go the Clinton route and say "I didn't inhale" then the FDA can't say we're endangering ourselves because we aren't inhaling!

Yeah, I agree. I only smoked a pack of FF menthols a day but vape 35-40mg/ml or stronger. However, I inhaled deeply and held it in to get the most nicotine possible. Others I know smoked more than a pack a day of FFs, but can only vape 20mg. It really does depend as much on how you smoked as it does on what you smoked.

Given the oppressive climate at the moment due to the FDA interference with freedom to vape I'd say a poll wouldn't be a good idea right now because it could be used against the freedom to vape movement in FDA propaganda.

Rocketman · 07-25-2009, 01:22 PM

Yea, one day we will go down to our local CVS Pharmacy, with our Doctor's prescription and pick up our month's supply (30ml) of Super High (12mg/ml) FDA approved e-juice.
I wonder what the Federal Medical Plan "copay" will be?

nurdcomp · 07-25-2009, 05:43 PM

So the answer is . . , 36mg (or whatever the level juice is) per ml. Thank you. Oh and has anyone bought a grip of bad mizers lately? I bought 6 from the vapor dudes that failed after just a few uses? They tell me I'm the only one with this issue, but I find that difficult to believe. I think some cheap-ass China wanna-be sweat shop started making them. BEWARE!

drD,

Sorry , I never responded to this one, way back when...

Here's (a copy n paste of) the answer....

Nicotine content in e liquid is usually measured in mg per ml. For example, 18mg e liquid would contain 18mg of nicotine per 1 ml of liquid. The exception to this is e liquid produced by manufacturer Johnson Creek which is measured in mg per 1.2ml.

So JC actual nic strength would be 5/6ths of the labelled value.

24mg liquid is actually 20mg per ml
18mg liquid is 15mg/ml etc..
