Mouth to Lung vs Direct Lung Vaping

Vaping is a better alternative to tobacco smoking.

All vaporizers have a similar assembly, and it needs a power source, which is the battery. Power from the battery heats the heating element that in turn vaporizes the e-juice producing in the atomizer. You then inhale the vapor through a small mouthpiece, and there is a vast collection of vape juices available.

However, two terms have created a lot of confusion in vaping communities and forums: mouth to lung and direct lung vaping.

What do they mean and how do they differ?

There are unending discussions on which is the better technique. We have gone to great lengths to research the differences between the two, how to choose the best vaping juice and how to go about vaping for the first time.

What Is the Difference Between the Two Inhaling Techniques?

The mouth to lung inhaling technique involves drawing the vapor into your mouth, holding it and then inhaling it into your lungs. Mouth to lung vaporizers have a tighter draw designed to mimic the draw of a cigarette. They use less power than direct to lung vapes.

If you are trying to stop smoking, the mouth to lung technique is the best choice, as it gives a lung hit. This technique is also subtle compared to the direct to lung vaping, since it produces less vapor and you can be discrete when vaping.

The direct to lung inhaling technique is similar to the flashy style of vaping seen on most vaping posters. All it takes is to breath in the vapor through your mouth directly to your lungs without holding the vapor in your mouth.

The technique produces a cloud of vapor when you exhale. Vapes with airflow control are the best for this technique since as you can adjust the airflow to achieve a mouth to lung or direct to lung inhaling technique. However, there are vaporizers designed for this technique.

Go Smoke-Free notes that direct to lung vaping is also known as straight to lung inhale, while you might see mouth to lung vaping abbreviated as MLT.

For smokers that are intent on quitting the habit, vaping can help you control the nicotine dependency and cuts out the over 4,300 harmful chemicals in cigarettes with 43 of the chemicals linked to cancer, such as tar.

Despite the vaping technique you use, the vapor must pass through your mouth, and some sites use the terms interchangeably, especially for their airflow control vapes.
