So, a co-worker asked me if there was still nicotine in the exhaled vapor. Logic would seem to indicate that there is, but is there? Does anyone know or has this been studied?

What if you hold it so that you don't exhale vapor???

The worry is that we work in a semi enclosed space (however there is very good airflow due to the ventilation system) and they were worried that they might be getting nicotine.

Nope. Or if there is, it's trace amounts. The overwhelming majority of the nicotine in vapor is absorbed before you even get it into your lungs - in your mouth and throat.

Even so, nicotine is in some common foods in small doses. Tomatoes are one, I believe. So nicotine is not a completely foreign substance to any of us, smoker or not.

Is there any documentation on the web to back this up? I would like to be able to show them something from an authoritative source.

Sure thing.

Look at section 5. It states that about 98% of nicotine is absorbed before the vapor is exhaled. Lots of other stuff on the safety of e-cigs as well.

This is the most comprehensive study of e-cig safety ever done as far as I'm aware. It's conducted by Health New Zealand.

GREAT Article

Nicotine in Mushrooms - The Food, Nutrition, & Science Newsletter with Phil Lempert! - Providing the latest information about food nutrition, science, technologies, news and trends.

See paragraph, Effect on humans: (Portion below)
Nicotine is usually associated with cigarettes, which also contain up to 4,000 other disease-causing chemicals, giving nicotine – and its addictive properties – a bad reputation. But at trace levels, pure nicotine is virtually harmless and has been thought by some to even provide health benefits.

Those who eat a varied and balanced diet actually consume trace amounts of nicotine on a daily basis. It is a naturally occurring compound (at very low levels) in tomatoes, potatoes, cauliflower, eggplant, chili peppers and some teas.

According to the cards vapor4life sticks in with every order, "what you see ... is made up of approximately 99% water, approximately 1% nicotine and some other flavoring compounds."

Of course there's no source cited, so take that with a grain of salt.

If they're talking about after the vapor is exhaled, it's actually even less.

Let's just take an average "high" nicotine juice.

18mg juice = 1.8% nicotine per volume.

Vaping, compared to cigarettes, is actually a rather inefficient nicotine delivery system. That's why you have to vape at a much higher dose than you smoke. Only about 40% of the nicotine actually makes it into the vapor. So by the time it reaches your mouth, you're only inhaling .72% nicotine.

If 98% of that is absorbed before the vapor is exhaled (as per the Health NZ study above), then that means that exhaled vapor contains .014% nicotine.

Even if we assume that vaporized delivery of nicotine is 100% effective, that's still only .036% nicotine in exhaled vapor.

That's WAY less than 1%. So actually, V4L is selling themselves short, if anything.

Wait......where does the other 60% of the nicotine go then?

I agree with this.Also we know that nicotine is fragile and is destroyed in light.So I wonder how much of what we exhale is destroyed by the light.

Destroyed in the vapourisation process from my understanding of it. It's similar with cigarettes, most of the nicotine is destroyed by the combustion in the cigarette rather than making it into the smoke.

But the statement was vaporizing compared to cigarettes. If you loose 60% of the nicotine from the vaporization process, it would stand to reason that you would loose more from a combustion process.

I am not trying to be argumentative or nip-picky, I just need good information so when someone tires to argue why I shouldn't vape I can counter with valid information.

The nicotine (and tar) numbers on the side of cigarette packs are measures of nicotine in puffs of smoke (using a mechanical cigarette smoking machine) rather than nicotine in the cigarette itself which is far, far higher. The issue with nicotine in e-juice is that we get a measure of the nicotine in the juice not nicotine in a puff from an e-cig. Not that that would be useful given the differences between attys in terms of temperature and such.

I'm not sure how this is useful for the debate you're talking about though since what's at stake is what's in the exhaled vapour not how much nicotine is lost in combustion. In the exhaled vapour there are none of the nasty chemicals that are found in secondhand smoke, i.e. the dangerous ones.
