This question has been asked on here a few times before I know. But I wanted to see what you guys think. Objectively and subjectively how much it is. I heard before its like 30 percent but someone else said 5. How much was it for regular cigs isn't it like 100 percent or like 50? You can post articles. Thanks for the help. I'm just curious

I would say about 40% ( max) since only a portion of the actual vapor ends up contacting the internal surfaces.....

if it was 100%, then there would be no vapor on exhale...
I actually like this explanation. And to those other guys if you see this ive seen the old studies. But with new gear should be easy to get a near equivalent nic fix in a few minutes. I found I'm not as addicted to nic as when I smoked. Maybe that's cuz I can take a few puffs here and there as opposed to feeling obgliated to finish a whole cig. Or maybe it's cuz there's no more additives idk.

Here you go, but keep in mind, the devices used in this study are not as powerful as the ones now. http://www.nature.com/articles/srep04133
And this paper shows that even with older style devices while chain vaping you can easily exceed nicotine level gained from a cigarette. And while nic level after smoking drops fast, nicotine level at chain vaping stays high all the time. So, it is difficult to compare smoking and vaping, but for sure with little effort we can exceed nicotine consumption of an average smoker.

This is a Very Difficult question to Answer.

Does a 7 Watt Cig-a-like Vaper using a Clearo absorb the same amount of Nicotine as a Cloud Chaser using a Quad-Coil at 150 Watts?

All depends on how much nic is being used. I'm assuming the cloud chaser uses 3mg. Honestly I used like 24 when j used a clear. Now I'm halfway in between a tootle puffer and a cloud chaser. A mod whomper as they call it so I'm running 12mg at 40 watts lol

What I was Alluding to, which I guess I did a Bad Job of making clear, is that it is hard to put an Absorption Rate as a percentage for Nicotine unless something is Known about the Hardware a person is using.

In the Early Days, a Study was done and it came back with an Average Absorption Rate (AAR) for Nicotine in the High Single Digits. For the Hardware at the Time, it seemed Reasonable.

Today, Hardware can produce MUCH More Vapor, and the AAR Numbers I have seen are more like 25 ~ 35%. This also seems Reasonable when I Normalize to the Lowering of Nicotine mg/ml that Many/Most people use.

Can you give me a link to those studies? Not that I don't believe you but that's just what I was looking for. And I thought the percentage of absorption was just how much of the vapor is absorbed. So maybe the percentage is still the same but since there is more total vapor per puff. You absorb it quicker. I hope that makes sense

Here is One of them...

http://www.ecigarette-research.com/web/index.php/research/2014/155-ecig-nicotine

I have whole bunch of these Studies somewhere. But like all-things-e-cigarettes, I have about 50 Links/Bookmarks for Everything. Finding things can sometimes be a PITA.

I'm a Pack Rat when it comes to Studies/Articles. And have been for the Last 5 Years.

LOL

Actually this study does not show what proportion of nicotine is absorbed. It shows that total nicotin in blood could be higher for vaper than for smoker.

If you have one that Does, Please Post it.

I kinda like this Graph....

srep04133-f4.jpg

"Data for tobacco cigarette was derived from Vansickel et al7. Nicotine levels after smoking a tobacco cigarette in 5 minutes (18.8 ng/ml) are 185% and 286% higher compared to using the first and new-generation electronic cigarette device respectively. Additionally, plasma nicotine levels after smoking one tobacco cigarette are almost equal to the values after using the new-generation device for 35 minutes (18.52 ng/ml), while they are 73% higher compared to the values after using the first-generation device for 35 minutes (10.88 ng/ml)."

That's the old study. I honestly think we are on third generation devices now and fourth if you count tc as separate. I still stand by what I said. The percentage stays the same but our new devices make more clouds. Its like the difference between putting a 12 ounce beer in a beer ..... Or a 40 ounce. They could both have the same abv. But more beer will make you drunker.

Compare your graph with this one (the same paper), it is actually the same graph but not cut after 35 min:

As you see, nicotine plasma level after 1 hour of vaping is considerably higher than after cigarette smoking.

Exactly... Nicotine Absorption is kinda a Moving Target.

And as Hardware Changes, so can Nicotine Absorption Rates (on Average) can also.

Oh they have been Done.

But the Problem Many Times with the Internet is Not being able to find things. It's Finding Too Many Things.

About Every Study that has Ever been Done with regards to e-Cigarettes has been Posted here on the ECF. It's just Finding it. Because many Times someone will post something like a Study in a Thread with a Title that has Nothing to do with Nicotine Absorption. So finding it can be a PITA.

I have about 2,500 ECF Threads currently Bookmarked.

What I'm saying is the rate as a percentage isn't changing. It certainly is per pull on your mod. We all remember having our ego mods like surgically attached to our lips lol. Either way its good news. It should mean peoples success rate for quitting will go up more

If you compare an hour of vaping to one cig it may be apples to oranges. During that hour a PAD or better smoker would have had at least one more. I would have had 2 more back In the day
