Vape spit back

Refers to the occasional popping sound that you hear when vaping, and small droplets of hot e-juice hit your tongue or lips. This phenomenon is not only unpleasant but also dangerous. Hot e-juice can cause burns in your mouth or throat, which can lead to serious complications.

There are several reasons

Why vape spit back occurs. In this article, we will discuss these reasons and ways to prevent vape spit back.

High PG e-juice

PG (Propylene Glycol) is a common ingredient in e-juice. It is responsible for carrying the flavor and provides the throat hit that mimics smoking. However, high PG e-juice is thinner than high VG (Vegetable Glycerin) e-juice. It is more prone to flooding the coil and spitting back.

Solution: The best way to prevent vape spit back is to use e-juice with a higher VG content. VG is thicker and provides better vapor production, reducing the chances of spit back.

Low wattage

Vapes work by heating the coil to vaporize the e-juice. If the wattage is too low, the coil may not heat up enough to vaporize all the e-juice, leading to spit back.

Solution: Increase the wattage to ensure that the coil is hot enough to vaporize the e-juice. However, be careful not to increase the wattage too much as it can damage the coil or burn the e-juice.


Flooding occurs when too much e-juice is added to the coil, and it cannot vaporize it all. The excess e-juice then spits back, causing vape spit back.

Solution: Ensure that you add the right amount of e-juice to the coil. Do not overfill the tank as this can cause flooding. Also, ensure that the coil is properly installed and tightened.

Faulty coil

A faulty coil can cause vape spit back. If the coil is damaged, it may not heat up properly, leading to flooding and spit back.

Solution: Replace the coil with a new one. Ensure that you buy high-quality coils from reputable sellers.

Chain vaping

Chain vaping refers to vaping continuously without taking a break. This can cause the coil to overheat, leading to flooding and spit back.

Solution: Take breaks between vaping sessions to allow the coil to cool down.

Inhaling too hard

Inhaling too hard can cause e-juice to be pulled into the mouth, leading to spit back.

Solution: Inhale gently when vaping.


Improper airflow can cause vape spit back. If the airflow is too tight, it can cause flooding, and if it is too loose, it can cause spit back.

Solution: Adjust the airflow to ensure that it is not too tight or too loose.

Dirty coil

A dirty coil can cause vape spit back. Dirt, debris, and residue can accumulate on the coil, preventing it from heating up properly.

Solution: Clean the coil regularly to remove any dirt or residue.

In conclusion, vape spit back is a common problem that can be prevented. By understanding the causes of vape spit back, you can take steps to prevent it. Ensure that you use high-quality e-juice with a higher VG content
