Vape pen dangerous??????

[James62736]

I am currently using a vape pen for my vaping needs, I have been doing it sporadically (not addicted) the Vape juice that I purchased has no nicotine and no diacytyl or an harmful substance. I was wondering if the Vape pen has the capacity to heat the vg and turn it into a dangerous substance because I heard that if vg gets burnt to a certain point then it converts into a dangerous substance
Ps: I have an evod vape pen, I have watermelon flavor as my e liquid and the pg to vg ratio is 70vg to 30of
So if you can please answer this important qushtion. Thank you...

In short no, you're safe as long as you don't run your tank dry. The potential production of harmful substances by burning e-liquid is generally associated with high power devices.

From my understanding the industry has long removed diacetyl from flavoring, at least the ones I order from the vendor explicitly makes "clear" options without it. the only harm comes from dry hits (inhaling burnt cotton and metal evaporates) when running tank too low as sonicbomb has mentioned. Nicotine without cancer stick poisons has been shown to be a regular stimulant. there is a great video on YouTube by UK doctor who talks about nicotine being similar to coffee, so I personally feel very safe.

have you ever lit the wrong end of the ciggie ( the filter) and inhaled it? nasty huh?
well the taste of burnt ejuice is even harsher than that... if it is even possible to inhale burnt ejuice, then you may have gotten to the point of causing some issues... I would bet that 99% of the people who vape wont/cant inhale burnt juice

Whatever you're heard is part of the witch hunt, with "testing" done by anti-vaping organizations.

Every "bad" results they got was manufactured by overheating the components to levels that no vaping device actually can do, at least not without a massive amount of mishandling, but the device would most certainly breakdown, explode or such at that point.

The only "bad" thing is burning your coil while dry, it which point you will burn the wink, and the metal of the coil could release some minute particles or simply melt, but any person that is vaping, would know right away by how bad the inhale would be, way before it would be actually dangerous.

+1. The short answer is no.

Absolutely. You should be able to taste it, but there are beginners that might not recognize it. And with an EVOD and high VG juice, it especially is possible if not likely. I'm a big fan of the EVOD (original -- you didn't say which you have) but fact is they 1) don't wick well with thick juices and 2) can be hard to feed a LOW enough power to. With a thicker juice or slightly too hot battery, they're still fine for short hits but after maybe 3 seconds the flavor passes its peak and starts getting dry and scratchy. Repeating this starts to cause a burnt taste.

One thing is they are designed for DOWN-regulating batteries, that is the battery cell is useful from 4.2 volts down to 3.3 but the chip takes it down to 3.7 anytime the cell is 3.7 or higher, so they don't have to bother with boosting voltage (the dropoff from 3.7 to 3.3 gives you some warning it's dying). Problem is, even 3.7 volts can be too high, at least with the original single coil types. With the 1.8 coil, even the 3.4 V minimum of a Spinner type battery can be too high. Tests of properly operating EVODs I've seen show a not necessarily dangerous level of formaldehyde, but noticably higher than more recent devices that are larger and run more conservatively. The dual coil EVOD 2 etc. is better in these areas but not immune.

The replies are correct, unless you puff too frequently or at too high a voltage or duration.... then very little harmful by-products are formed. When you taste burnt material, as in a dry-puff, then the coil is getting too hot. At high heat the organic material in e-liquid will oxidize, the degree of oxidation is both time and temperature dependent. Really common sense. Even if you do get occasional dry-puff it has been shown in studies that the amount of potentially dangerous compounds produced as still less than the inhaled vapor from a tobacco cigarette. Good to be cautious!

Tests of properly operating EVODs

Do you have links to these tests? I would like to peruse them and,archive for
future reference.

I have been a bit lazy over the last several months in trying to keep up with the journal literature. But below are several that I think are worth reading:

Sorry about not including direct links. I am a newbie and cannot upload files yet. But hope to post information on coil temperatures that myself and a friend collected. We tried to get this published by numerous journals and no luck. The work was considered either too technical or having insufficient supporting evidence. It is hard for the individual to have enough resources to get something published.... analytical equipment such as gas chromatographs/mass spectrometers, NMR's, etc. just are not found in too many house basements!!

 

[mcclintock]

I don't remember where I saw that, but sounds like there's some stuff to look at posted

 

[Spencer87]

any battery is dangerous if you do not understand what you are doing and you push it past its limits

 

[skoony]

Double post

 

[ChuckMichigan]

Spencer87 Sorry if I am misunderstanding, but the information about by-products being formed under dry puff conditions are about coil temperature, not about battery temperature.

I apparently didnt read the thread well enough.
