The Story Behind Vape Spitting

Vape spitting is a common and frustrating problem for UK vapers. This happens instead of the liquid turning into vapour. It can create an unpleasant and sometimes messy experience.

At Vaping News, we’ve seen that most cases of spitback are caused by technique or device setup rather than a fault. The good news is that these issues can be easily fixed without replacing your device.

Spitback often happens when there’s too much e-liquid in the coil. When the coil heats this liquid unevenly, it produces droplets that shoot into your mouth. Several issues can cause this, such as:

• A flooded coil
• Over-priming the coil
• Drawing too hard or aggressively
• Using e-liquid that is too thin for your device

This Guide Explains

This guide explains everything UK vapers need to know about vape spitting. It covers:

• Why does e-liquid shoot through the mouthpiece
• Common causes of spitting, gurgling, and crackling
• Step-by-step fixes to stop vape spitting quickly
• Correct coil priming to prevent spitback from day one
• How PG/VG ratios affect spitback
• Safety considerations and whether spitback is dangerous
• Practical advice to prevent spitback over the long term

By following this guide, UK vapers will understand how to eliminate spitback. They’ll also be able to enjoy a smooth, consistent vaping experience.

What Is Vape Spitback?

Vape spitback is when hot droplets of e-liquid shoot out of the mouthpiece when you inhale. This usually happens when e-liquid floods the coil. Instead of turning into vapour, the liquid “pops” and is spit upward.

Spitback is often accompanied by gurgling or crackling sounds. This indicates liquid has pooled where it shouldn’t be, such as inside the chimney or around the coil. Ideally, the wick should absorb all e-liquid evenly, preventing pooling and spitback.

Common Causes of Vape Spitting

1. Flooded Coil

A flooded coil is the single most common cause of spitback. Flooding can happen if the pod or tank is overfilled, the device is left on its side for too long, or you draw too hard. Using a thin e-liquid in a pod not designed for it can also cause flooding, as the coil cannot vaporise the liquid quickly enough.

2. Over-Primed Coil

Priming a coil is essential, but over-priming saturates the cotton beyond capacity. Excess liquid has nowhere to go and can spit out on the first draw.

3. Drawing Too Hard

New vapers or ex-smokers may pull too aggressively. Hard, rapid draws flood the coil instantly. This causes e-liquid to fire through the mouthpiece instead of vaporising properly.

4. Wrong E-Liquid Thickness

High PG or thin liquids wick too quickly in devices designed for 50/50 PG/VG blends, causing spitback. Conversely, high VG liquids in low-powered pods may lead to dry hits rather than spitting. Matching your e-liquid to your device type is essential for a smooth experience.

5. Incorrect Wattage

Vaping below your coil’s recommended wattage prevents efficient liquid vaporisation. The liquid accumulates, eventually popping and spitting. The recommended range is usually printed on the coil itself.

6. Worn or Damaged Coil

Coils have a limited lifespan, typically one to two weeks for moderate users. Degraded coils do not heat evenly, and residue from sweet liquids can build up, resulting in gurgling and spitback.

7. Blocked or Restricted Airflow

Blocked airflow traps condensation and liquid in the chimney or mouthpiece, which can shoot upward when inhaling. Regularly cleaning airflow vents reduces this risk significantly.

Step-by-Step Fixes to Stop Vape Spitting

Step 1: Flick the Device

Hold the vape with the mouthpiece facing downward and give it a firm flick a few times. This helps dislodge any pooled liquid from the coil or chimney. Wipe away excess e-liquid with a tissue.

Step 2: Clean the Chimney and Mouthpiece

Use a rolled tissue, cotton bud, or pipe cleaner to absorb liquid inside the mouthpiece and chimney. Doing this every few days prevents pooled liquid from causing repeated spitback.

Step 3: Switch to Gentler, Slower Draws

Replace short, hard draws with longer, moderate inhalations of two to three seconds. This reduces liquid being pulled too quickly into the coil, allowing it to vaporise properly.

Step 4: Check and Adjust Wattage

Ensure your device operates within the coil’s recommended wattage range. Increase wattage if it is too low, or confirm the coil matches the device output if there is no adjustable wattage.

Step 5: Check Your E-Liquid

Use the right PG/VG ratio for your device. Standard UK pod kits work best with 50/50 nic salts, while sub-ohm tanks require 70% VG or higher. Using the wrong liquid thickness can result in flooding or dry hits.

Device Type	Recommended E-Liquid	Using the Wrong Liquid
Pod kit / MTL device	50/50 or nic salt	High PG can flood the coil and cause spitting
Sub-ohm / DTL device	70% VG or higher	Thin liquid causes flooding and spitback
Pod kit with high VG	Not recommended	Dry hits and shortened coil life

Step 6: Replace the Coil or Pod

If all previous steps fail, the coil is likely worn. Replace it, prime properly, and wait 5–10 minutes before vaping. A fresh coil usually resolves persistent spitback.

Coil Priming Tips to Avoid Spitback

Over-priming is a common beginner mistake. Apply two to four drops of e-liquid directly to the exposed cotton holes. Avoid flooding the coil cavity. After filling the pod or tank, wait 5–10 minutes for saturation. Take two to three gentle draws initially to allow proper wicking.

Why PG/VG Ratio Matters

E-liquid thickness plays a major role in preventing spitback. High PG liquids wick too quickly, oversaturating small pod coils and causing spitback. High VG liquids are thicker and wick more slowly, which can lead to dry hits if misused in low-powered pods. Always match your liquid to your device’s recommended VG/PG ratio.

Is Vape Spitting Dangerous?

Mild spitback is unpleasant but not considered dangerous. Excessive spitback, however, indicates a problem that should be addressed. Check for damaged pods, cracked tanks, or worn coils rather than continuing to vape through them.

Common Questions

Why is my vape spitting e-liquid?

There are several reasons why your coil might be flooded:

• Overfilling the tank
• Drawing too hard
• Over-priming the coil
• Using a thin e-liquid
• Incorrect wattage settings

How do I stop my vape from spitting?

There are several ways to stop a vape from spitting:

• Flick the device downward: A quick flick can help clear out excess e-liquid.
  Draw slowly: Avoid aggressive inhales that can flood the coil.
• Check the wattage: Ensure your device is set to the recommended wattage for your coil.
• Replace coils or pods: If the coil is old or worn out, it’s time for a replacement.

Why is my pod gurgling?

Gurgling occurs when liquid is trapped in the coil or chimney. Likely causes include overfilling, drawing too hard, or worn coils.

Can over-priming cause spitback?

Yes, excess drops on a new coil saturate cotton beyond its capacity, causing spitback on the first draw.

How often should I replace the coil?

Most coils last 1–2 weeks for moderate users. Heavy, sweet-flavoured liquids may shorten lifespan to one week. Replace coils when flavour fades, or gurgling occurs.

Final Verdict

Vape spitting is frustrating but rarely indicates a broken device. Most issues stem from excess liquid, wrong e-liquid viscosity, aggressive draws, or worn coils. By understanding these causes, preventing spitback becomes simple. – Correctly prime your coil

• Inhale gently
• Choose the right e-liquid
• Clean your device regularly
• Replace your coil when needed

These steps will resolve spitback for most UK vapers.
