There are a number of reasons why your vape is leaking into your mouth. These include a flooded coil, blocked airflow, incorrect storage, or a faulty device. Here's how to identify and fix each one.

Why is vape liquid getting into my mouth?
E-liquid enters the mouth (called "spitback") when liquid pools in the coil chamber rather than vaporizing. Common causes:
- Chain vaping — rapid consecutive puffs flood the coil with e-liquid faster than it can vaporize
- Pulling too hard — aggressive draws pull liquid into the airflow path instead of through the coil
- Storing mouthpiece-down — gravity pulls e-liquid into the coil chamber
- Blocked airflow vents — restricted airflow causes pressure buildup that pushes liquid up the mouthpiece
- Nearly empty device — as e-liquid depletes, air pockets can create spluttering
How to fix vape leaking into mouth
- Clear the mouthpiece — blow gently through the mouthpiece with a tissue on the other end to clear pooled liquid
- Slow your draw — take slower, 2-3 second draws instead of aggressive puffs
- Store upright — always store your vape mouthpiece-up
- Wait between puffs — allow 20-30 seconds between draws to let the wick re-saturate and the coil clear
- Check airflow — open the airflow slider if restricted

When to replace your device
If spitback continues after trying these fixes, the coil may be saturated or worn out. Replace the device — browse the full disposable vapes collection at NicMafia.
FAQs
Is it harmful to swallow vape liquid?
Swallowing a small amount of e-liquid is generally not dangerous for adults, but it's unpleasant and the nicotine can cause nausea. If you regularly get liquid in your mouth, fix the technique or replace the device.
Why does my new vape spit?
A new device that spits immediately may have been primed incorrectly or have a flooded coil from factory. Try a few slow primer puffs without activating to help the wick absorb properly before normal use.
