Potentially Dangerous

This article appeared today in Science Daily.

It literally made me sick to my stomach. I tried to access the full journal article but they wanted $35 to actually get a look at it. It appears from the abstract that the methodology was all wrong. It seems to me that the powers that be are not just looking for regulation and taxation but an outright ban on vaping.

If they don't post the source, it don't believe a word they say

They are claiming... 250,000,000,000,000,000,000,000,000 free radicals per puff at 3.3 V for every ecig/juice tested

They post it. I am going to read it now.

"when the device's heating coil heats the nicotine solution to very high temperatures"

Would really like to know if the (very high) temperature was that of the outer layers of the Sun or something that a human being can inhale...

"They found that e-cigarettes produce high levels of highly reactive free radicals that fall in the range of 1,000- to 100-times less than levels in regular cigarettes."

"The levels of radicals that we're seeing are more than what you might get from a heavily air-polluted area but less than what you might find in cigarette smoke,"

Would anyone reading it be willing to post up a "cliffs notes" or "TLDR" version of it for those of us that are busy doing other things but would like the jist of what it is actually saying?

Actually, it is a good paper for ex-smokers. Here is the paper:

An Error Occurred Setting Your User Cookie


Authors do know about dry hits, they even tried (in separate experiment) to simulate them, but got less free radicals then when there were no dry hits.


For flavored juice it was found that amount of free radicals was 10 times higher than in “polluted” air, but 100-1000 times lower than in cigarette smoke (data was extrapolated to “daily dose”, assuming that vaper takes 200 puffs/day).


So, we can assume that free radicals for ex-smokers are not a problem.


Here how experiment was conducted:


Generation of EC Aerosols: ECs were connected to house vacuum via a flow meter and aerosols were generated by manually turning on the fully charged EC battery at voltages adjusted to either 3.3 V or 5.0 V. Puffs were simulated by turning off/on the flow (vacuum) and voltage (battery) simultaneously. Topography parameters used were based on human usage conditions as described previously1 and were as follows: puff duration, 5 sec; puff interval, 20 sec; flow rate, 500 ml/min: and number of puffs, 40 per experiment


Aerosols were generated (Figure S1, described in detail in theSupporting Information) using commercially available EC batteries (eGo-ce4 3.3 V and Tesla 3.0–6.0 V), cartomizer (SmokTech: XXL, 1.5 ohms resistance, dual heating coils)

EDIT: Afterthought: 200 puffs from CE4 and (how many?) puffs from .3 coil are not the same...

They found that e-cigarettes produce high levels of highly reactive free radicals that fall in the range of 1,000- to 100-times less than levels in regular cigarettes.
"This is the first study that demonstrates the fact that we have these highly reactive agents in e-cigarette aerosols," Richie said. Results were published in the journal Chemical Research in Toxicology.
"The levels of radicals that we're seeing are more than what you might get from a heavily air-polluted area but less than what you might find in cigarette smoke," Richie said. The radicals are produced when the device's heating coil heats the nicotine solution to very high temperatures.

How strange...

They found that e-cigarettes produce high levels of highly reactive free radicals that fall in the range of 1,000- to 100-times less than levels in regular cigarettes.

This good news.

Can you imagine a fuel that produced 100-1000 times less carbon monoxide leaving the tailpipe?
The world would grab it with both hands and rewrite history.

just getting ready to post the same quote you did DJ...

1000-100X less than ciggies... gimme my vape

thats more than a mole of radicals... and if in a gassious state thats about 224 liters volume... avg lung capacity is umm 2.7 L

I might have done the math wrong, I am good at that
2.55 X 10¹³ X 10¹³

blah superscript isn't turned on

I know about some stuff that's horribly dangerous in vapes, if you send me $35.00 I will tell you about it. The GoFundMe info is....

Potentially dangerous molecules detected in e-cigarette aerosols

"This is the first step," Richie said. "The identification of these radicals in the aerosols means that we can't just say e-cigarettes are safe because they don't contain tobacco. They are potentially harmful. Now we have to find out what the harmful effects are."

Richie is currently conducting studies to carefully measure total numbers of free radicals in e-cigarette aerosols and to identify their chemical structures.

"That will help us interpret the data better to know how dangerous they are," he said.



They say they don't know if the molecules are dangerous. Basically the article is meaningless.

lol, like the news stories, "There is something in your house that might be deadly if you have children!!!! Tune in next Thursday at 11PM for more info"

Well in all fairness the kids will be locked in the dunge....I mean playing in the basement till then.

 

[exo72069]

My point exactly. The facts buried in this article say that vaping is a whole lot better than smoking and a whole lot better than breathing city air 24 hrs a day.

But the tone of the article, the twisted truths, the vague assertions, and the outright lies, gives the naive reader the impression that these brave scientists have disinterred the gruesome truths about the deadly hazards of vaping. I and probably everyone else have read worse. But what really disturbed me was that a site like "Science Daily" which I have heretofore read every day or two, would publish such drivel.

Actually it said 2.5 * 10^13 to 10.3^13 which would be 25,000,000,000,000 to 36,713,342,000,000.

Gotta be careful around that dihydrogen monoxide. After all, every person who has died young has had a significant amount of dihydrogen monoxide in their body.
