I never chain smoked (except maybe while on (OTHER STUFF) in college) so can't speak to the same experience but I'm wondering if maybe the difference you are describing has more to do with carbon monoxide in your system? Just my unscientific guess. Did you mean 3mg, not .03mg as that is basically no nicotine at all.
yeah, I meant 3mg

The nicotine in combustible cigarettes is quickly absorbed in the lungs -- the very small particulate size in smoke achieves better penetration into the airways, while the nicotine in vapor (larger droplet size, relatively speaking, doesn't penetrate the lung airways as well) is better absorbed in the mucus membranes of the mouth/throat/nasal-passages. So, the primary mechanism of how nicotine gets into the blood stream is very different, making direct comparisons of nicotine intake from smoking and vaping less meaningful.

Furthermore, juul's studies on nicotine plasma levels showed it took much higher nicotine levels in vaping to approximate cigarette smoking ... upwards of 50mg/ml were projected to approximate the rapidity and levels of nicotine plasma levels seen in cigarette smoking.

Can you provide a link to the any of the studies? We all know studies conducted or sponsored by the manufacturer (sometimes in a very roundabout way) are highly suspect due to the obvious bias. I love to find reliable facts with specific numbers. Right away when you say 50mg/ml and then say "cigarette smoking" I wonder what does "cigarette smoking" mean - unfiltered cigarettes or an ultra light?

I'm sure the absorption is different, I have no debate about that. But it appears so far, we aren't able to accurately quantify how much different.

I swear I searched far and wide for e-salt juice lower than 35mg and couldn't find any. Or maybe it was I couldn't find any that were at least 50% VG? Can you suggest some? I'll consider the mixing. I just noticed my vaping habit increasing and wanted to keep things at bay. I DID think about putting the vape in another room, or limiting myself to only certain times a day. The cig smoking was fairly self limiting due to the nasty taste/smell and the fact there is no way in hell I would do it in my house or car (not to mention the cancer concern always in the back of my mind.) Vaping is SOOO much better. It's amazing though how hard it is to get fellow smokers to switch! I tell them you just need to stick with it a few days to let your throat get used to the different feel of the hit and then you will NEVER go back and kick yourself for not switching a long time ago! But I know I'm preaching to the choir here on that.

On the mixing, I'd wonder if you CAN make your own e-salt juice with lower than say 25mg than why is it virtually non-existent (as far as I can tell). I had assumed it had something to do with a limitation in the difference of the chemistry between salt and freebase. (But this is probably for a different topic/thread - sorry.)
A quick search for low nic salt juice yielded this:

There are other variables to smoking which should be taken into account too. Such as smoking indoors regularly would include passive smoking, which will increase the amount of nicotine intake quite dramatically. Depending on how much a smoker smoked indoors, they will continue to inhale tobacco smoke with every breathe.

Anyway, vaping too much nicotine some side effects would become apparent. Also, more than enough nicotine is much better than not enough. Not enough would see a vaper moving back to tobacco products.

HOLY CRAP! Is this really correct?
No. Cigarettes contain far more nicotine than that. The amount printed on the package is how much is absorbed when you smoke one. You do not absorb all the nicotine in the e-liquid you vape, anymore than you absorb all the nicotine that's present in the tobacco in a cigarette.

The reason you got a lot of "I/we don't care" is that most of us here weren't social smokers, we were hard core smokers, and many of us had given up on ever being able to quit until we tried vaping. So we tend not to worry about how much nicotine we consume, provided it's enough to keep us from smoking.

safe distance from a black hole
I have been a pack a week Marlboro Light Smoker (basically a social smoker) off an on over the years. I gave vaping a try a few years ago using e-juice with freebase nicotine (12mg I think it was) and didn't like it. For one I found the PG I was mildly allergic too (gave me mild asthma when I smoked it), going with a high VG fluid though solved that. But it still didn't "feel" as pleasurable for an occasional smoke as smoking a Marlboro Light.

Fast forward to more recent and I decided I don't want the all the crap in my lungs that comes with inhaling burning material. So I read up on nic salt based e-juice. I was a bit surprised you can't get it in anything less than 35mg/ml. Picked up an eGo AIO (using 1 ohm coils - equiv of 14-18 watts) and some 35mg salt e-juice, got used to the different throat hit feel compared to smoking, and I ended up loving it! No stinky smoke breath, lungs feel way better (even though I wasn't a frequent smoker.)

The downside is that with the vaping, especially since I use a mild tobacco flavored juice (American Patriot), it doesn't stink up my car or house so I can smoke it like pretty much anywhere, anytime. So I'm finding where before, I'd have to stop working and go out on my deck to smoke a cig, I can vape while sitting at my home office desk!

So I've realized, I'm actually smoking (vaping) a lot more than I smoked because of the convenience. But still not a lot. (Or at least I thought!) Currently I'm going through about 1 30ml bottle of e-juice every 3 months. I'm probably filling my eGo (a 2ml capacity) 1-2 times per week, lets say 1.5 times a week on average, so I'm probably going through about 3ml a week which is about right as then that is about 2 and a half months to go through one 30ml bottle or about my original estimate have how often I go through a bottle.

The thing I'm a bit freaked out about is the calculations I recently did which are...

Marlboro light have 0.8mg of nicotine per cigarette. I never smoked them down that far so I bet I smoked the equivalent of 0.6mg per cig. At 20 cigs in a pack, one pack a week, that's 12mg of nicotine a week.

With the 35mg e-salt juice, if I'm smoking 3ml a week, that's 105mg of nicotine or the equivalent of 175 cigs with 0.6mg each or 8.75 packs a week or a little over a pack a day.

HOLY CRAP! Is this really correct?

Now I know vaping is way more "healthier" than smoking, and moderate nicotine intake isn't all that bad from what I've read (similar to caffeine intake) as long as it's done in moderation, but does it boil down to that the majority of vapers that were smokers have probably not taken time to "do the math" like this and don't realize they are probably taking in WAY more nicotine than they did when they were smokers?
Hi,
Ive come to understand through reading posts and threads on this and other vaping forums that most people that visit forums regularly are aware that they consume more mg's of nicotine vaping than they ever did using tobacco. Its simply not as great a revelation as you might think it is.
Most of the nic you use vaping goes to waste either through exhaling or through urination etc. Vaping isnt as efficient as cigarettes at delivering the nicotine so, you use more.
For the last 5yrs as a smoker I had about 9-10 cigs a day which worked out to about 10-12mg of nic used a day. Each one of those cigs contained about 10mg but I used about 1.2mg. When I started vaping I was using about 108mg of nic a day from about 6ml of 18mg juice, but still wanted a cigarette.
Now, 18months later I use about 11mg a day from about 3.6ml of 3mg juice. I got to that point by simply putting the vape down and vaping only when I felt like it rather than cultivating a habit of chain vaping.
If you are concerned about how much nic you are consuming use juice that has less mg's! Its readily available everywhere right down to 3mg and if you take up DIY you can mix up what ever dosage you are comfortable with. You dont have to use 35mg juice.
I think that its really up to you as to how much mg's you use and how much you vape. If you arent comfortable at where you are at simply reduce the amount you use.

Cheers

This is almost if not impossible to measure. Think about all the variables involved for a minute.

One would have to measure blood plasma levels in people. That's been done, and the fact that nic is absorbed from vapor less efficiently than from smoke is what motivated Juul to create the product that they did (5% nic by weight, 59 mg/ml, protonated nic to make it palatable).

Yes, it's a fool's errand to try to compare nicotine absorption levels between smoking and vaping. Pretty pointless as well unless you're into navel gazing or spreading propaganda. Thankfully we have this marvelously evolved instrument called the human body with a balancing feedback loop that sends pleasure sensations until it's had enough, then increasingly violent sickness sensations when it's had too much. Most of us are able to strike a balance quite naturally.

If references are your thing, here you go, this article gives information on nicotine absorption, rates and delivery based on lab determinations. These are for cigarettes. I have no links off hand to vaping with new generation vaping products for comparison. you'll note that the article estimates roughly 1 mg of the 12 mg present in the amount of tobacco in a standard size cigarette was their determination that was absorbed.

It might be interesting to read the comparative studies for nicotine absorption by Russell et al. (1979) and follow up research by Benowitz et al. (Most notably 1988). Their studies compare blood nicotine levels after smoking and after chewing nicotine gum or using chewing tobacco (and other slow, oral release tobacco products).

Reading this side by side with Farsolinos' 2014 and 2015 studies on nicotine absorption shows very similar blood nicotine levels for vaping 18 mg/ml juice and a cigarette.

The difference is of course in the period that this level is kept up. For vaping, the level tends to creep up slowly and then to be kept there by the user for much longer. This effectively means there is a greater intake of nicotine.

As for how much nicotine is effectively absorbed from juice vs a cigarette? I don't think you will find that data* There are too many variables, both in the consumable, the way of consumption and in the way the user's body reacts.

It is more important to note how much people tend to consume and until which blood nicotine level they will keep consuming.

*Edit: good, 'independent' and complete data, sorry. There is some stuff out there.

Often times folks try to compare apples to apples when actually it's apples to bacon.

If your bp aint all jacked up, pulse racing like a racing rabbit or you sleep ok at night don't sweat it.

Maybe think of it this way...every extra molecule you now take in from vaping nicotine used to be carbon monoxide from tobacco smoke.

Yes he can lower his nic, but he is probably mtl and only vaping 3mls per week, so if he lowers to 3mgs mtl at 3mls per week, I dont think that would cut it and with such a low amount of nic in his system, he might get some thoughts of cigs or increase his ml intake....its possible though a super low nic could work for him though

I have no links to any independent studies of nic absorption between cigarettes and Juul. Here's a link to 2017 study comparing various devices and nic levels to cigarettes ... the short version, nothing equalled cigarettes for nicotine delivery, but the one that came closest in that study was Vuse using 48mg/ml.

You're just gonna make a long thread mate. The fact is not even paid or independent volunteer studies can provide 100% accurate details. All will be just averages. And the truth will still vary person to person. Like when I light a smoke when I'm playing a PC game, I just puff it once or twice and forget about it 'til it burn out. So did I consume a stick doing that? I mean, your body knows if you had enough. I'd say you or many of us consumes the same amount of nic when we were smoking and now that we are vaping. The approach is just vape and vape until the cravings go away. So when that happens, you know you had enough. And that is probably the same amount of nics you needed when you were smoking because your body just felt satisfied. Believe me, many of us here knows when we had too much. Or in my case even caffeine, in cola or coffee. In practice, you should too. So in the end, you will just consume the same, it's just the delivery system that's changed.

No need to get defensive. I really don't care about anyone else's nicotine intake, just pointing out some interesting observations I've made and trying to make sure I wasn't making a mistake in my calculations.

The American Patriot 35mg salt based e-juice is 35% PG, 65% VG, so if you believe e-salt juices have to be all or close to all PG, you've been misinformed.

To each their own as far as what and how they want to vape. I don't judge. I think you meant "I don't care" and not "We don't care" as I don't think anyone here can speak for all vape users.

If you're concerned, there are sub-ohm salts that have 0-6 mg nic.

I get the whole more convenient to vape thing even though it is verboten in many places like cigarettes.

I sneak puffs from my vape in dozens of places I would not dare light a cigarette. Elevators, public restrooms, hotel rooms, stuff like that there...

But my method leaves a hint of aroma at worst. The other evening I saw a group of young fellows (in their 20's) all meet in a parking lot. Everybody lit up a cigarette except one guy. They all puffed on their cigarettes and drank from bottles of beer. The one guy vaped. Each time he exhaled the crowd practically disappeared in his fog. My brother vapes in a day what takes me a week. I gave him a 30ml bottle of some yummy sauce and he asked if they sold bigger bottles because it didn't last him all weekend. He used to smoke about 20 ultra light cigarettes a day.

At one point I mixed a 35ml salt with a 3ml freebase of like flavors for about 19ml average. But what I learned over time was more nic was not the answer, at least for me. I just chain vape twice, maybe 3 times for what would be each drag from a cigarette. About ten to twelve puffs total per minute. After about a minute I no longer want to smoke. That's using a 3ml sauce at 70% vg.
