Exxus Quick Brief
What You Should Know
A quick rundown of the main points, questions, and guidance you'll find in this guide.
Overview
How you draw on a vaporizer changes the feel of every session. This guide compares two draw styles, mouth to lung and direct to lung, and explains how airflow and device type affect each one so you can find what suits your dry herb or oil cartridge sessions.
Mouth to lung means you pull vapor into your mouth first, then breathe it in, which gives a tighter, more controlled draw. Direct to lung means you inhale straight into your lungs for a bigger, airier pull. Neither is better, it comes down to your device and your preference.
Key Takeaways
- Mouth to lung means drawing vapor into your mouth first, then inhaling it, for a tight, controlled pull.
- Direct to lung means inhaling vapor straight into your lungs, similar to a deep breath.
- Tighter airflow suits mouth to lung, while more open airflow suits direct to lung.
- Many new vapers find the mouth to lung draw more familiar and easier to start with.
- Direct to lung tends to produce a bigger, airier draw and larger vapor volume.
- Adjustable airflow on your device lets you experiment and settle on the draw you prefer.

Category Breakdown
Below, the full guide breaks down the category, how people use it, and how to choose within it.
Every vaporizer has its own feel, and a big part of that comes down to how you draw. There are two main inhalation styles, mouth to lung and direct to lung, and knowing the difference helps you get more out of your device.
With a vaporizer, your material is heated rather than burned, so the vapor comes through smoother and cooler. That vapor can be enjoyed two ways: mouth to lung (MTL) and direct to lung (DTL). Here is how each one works.

What is Mouth-to-Lung?
Mouth to lung (MTL) is a technique where you first draw vapor into your mouth, hold it for a moment, then breathe it into your lungs. It uses a tight, controlled draw and pairs well with lower power devices and oil cartridge vaporizers.
MTL is a great starting point if you are new to vaporizers. The slower, more deliberate draw gives you more control over each pull and is easy to get comfortable with.

What is Direct-to-Lung?
Direct to lung (DTL) is a technique where you inhale the vapor straight into your lungs in one smooth breath, similar to taking a deep breath of air. It differs from MTL, where the vapor pauses in your mouth first.
DTL usually calls for a device with more airflow and lower resistance to handle a larger volume of vapor. It tends to produce a thicker cloud and a fuller flavor, which is why many experienced users and cloud chasers prefer it.
DTL delivers bigger clouds and a stronger pull than MTL. It is popular with seasoned users, though it can feel like a lot for someone just starting out or anyone who prefers a more subtle session.
What is the Best Technique?
The right technique depends on your experience, your device, and the kind of session you enjoy. Beginners often start with mouth to lung for its control and comfort, while seasoned users may lean toward direct to lung for bigger clouds and fuller flavor. Some newcomers take to direct to lung right away, so it is worth trying both to see what suits you.
In the end, mouth to lung and direct to lung are both valid, and the best one is simply the one you enjoy most. Try them for yourself and explore the vaporizers at ExxusVape.com.

Common questions about this guide and how to put the information to work when choosing your device.
What is mouth to lung vaping?
