Boiling liquid in the mouth when using the electronic cigarette: how to fix it

Hot liquid in mouth if you vape e-cig | Terpy

Do you burn your tongue with an e-liquid while you vape? Here’s why it happens and how to prevent it from happening again

How hot is the liquid in the e-cigarette when our device bubbles up and starts emitting glowing droplets?

A lot, really a lot!

It is a frequently occurring problem that ruins the vaping experience for many vapers.

Not only do you risk burning your tongue, but simply inhaling through an e-cig mouthpiece and feeling liquid in your mouth (instead of normal vapor) is a truly unpleasant sensation.

Are you also facing this problem?

If so, you’ve come to the right place: in the following article I’ll explain why your electronic cigarette emits hot liquid and how to intervene so that it doesn’t happen again.

Why does my electronic cigarette ‘spit’ incandescent drops?

Your cigarette could start emitting droplets of hot liquid for several reasons, but in most cases, this phenomenon occurs because the inside of the coil has been ‘flooded’, as they say in the slang.

But what does that mean exactly?

Simply put, resistances or resistors consist of a coil of metal wire wound into a spiral. This is inserted into a cotton cylinder that absorbs the liquid for the vaporizer. When you activate your device, the coil heats up, vaporizing the e-liquid that the vape inhales.

Under optimal conditions, the liquid should never end up inside the resistance. However, it can happen that the e-liquid infiltrates through the cotton and accumulates in this space, flooding it. And when it happens, the activation of the electronic cigarette can cause the emission of those droplets that have burned your tongue.

Coil flooding can occur due to:

  • the degradation of the cotton that is no longer able to retain the liquid and allows it to pass inside the resistance.
  • use the device with wattages that are too low. If not, enough power is supplied to quickly vaporize the liquid absorbed by the cotton, it can in fact accumulate inside the resistance.
  • use of an e-liquid not suitable for the coil. Each resistance is manufactured in such a way that it adapts better to liquids with a certain viscosity. Those for direct lung vaping are designed for the thickest e-liquids. Mouth-to-lung vapers, on the other hand, are designed for less viscous liquids.

Is it dangerous to drink e-liquid?

Those who experience the unpleasant sensation of liquid droplets in their mouths during vaping may fear possible ill effects from accidentally ingesting the latter. In most cases, however, ingesting tiny amounts of e-liquid does not pose a health risk.

These products, in fact, are made up of propylene glycol (PG) and vegetable glycerin (VG), two harmless substances that are also frequently used as food preservatives. The other ingredients are e-liquid flavors concentrates and liquid nicotine.

Often, the former has a composition almost identical to their equivalents used in the food industry: therefore, they are also harmless to health.

What about liquid nicotine?

To tell the truth, this substance can be extremely dangerous for humans and cause serious and potentially fatal poisoning, but only if taken in high concentrations. Consequently, the accidental ingestion of tiny amounts, such as those contained in the liquids of electronic cigarettes, does not constitute a danger.

In any case, to avoid the slightest risk, it is advisable to stop vaping immediately when you realize that the e-cigarette is emitting droplets. The vaper will be able to enjoy his e-cig again after solving this problem.

How to make sure you don’t inhale more hot drops of e-liquid

Now I just must explain how to intervene when your vaping device starts to release hot drops.

First remove the flooded resistor. You could try leaving it at rest waiting for the liquid that has accumulated inside to dry, but I suggest you throw it away and replace it with a new one. Better safe than sorry.

Before mounting the new coil, make sure it is suitable for the type of liquid you are vaping. If you are using a viscous e-liquid like those with a high VG/PG ratio (for example, 70/30), choose a coil designed for DTL. Conversely, if the ratio between the two substances is low (for example, 50/50), mount a MTL coil.

While vaping, make sure to set a suitable wattage for the new resistor: on the outer surface of this component, the manufacturing companies engrave the wattage range within which you should keep your device to avoid any malfunction.

Finally, remember to change the coil at regular intervals: ask your trusted dealer for information about the average duration of your resistors and never use them more than recommended.

In conclusion

Now you know why your e-cig suddenly started ‘spitting’ hot liquid: the coil has flooded, and you need to replace it to solve this problem. Once you’ve done that, be sure to check that the resistance is adequate for the liquid and that the wattage is adequate.
