Introduction
Learning how to inhale a vape pen correctly is often the most overlooked part of the vaping experience. While it may seem as simple as taking a breath, the technique you use directly impacts the flavor, the vapor production, and how your throat reacts to the vapor. At Vapor Authority, we frequently help adult vapers navigate the nuances of their hardware to ensure they are getting the best possible performance from their devices. Whether you are using a compact pod system or a high-powered box mod, mastering the right inhalation method is the key to a consistent and enjoyable session.
Warning: This content is intended for adults of legal vaping age only. Vaping products contain nicotine, which is an addictive chemical. These products are not intended for use by minors, non-smokers, pregnant or breastfeeding women, people with heart conditions, high blood pressure, or asthma. Consult a physician if you have concerns about whether vaping products are appropriate for you.
Understanding the mechanics of your device is the first step toward a better experience. Vaping is not a one-size-fits-all activity; the resistance of your coil, the airflow of your tank, and the viscosity of your e-liquid all dictate which inhalation style you should use. This guide will break down the two primary methods of inhalation, the hardware that supports them, and how to troubleshoot common issues like coughing or "spit-back."
The Two Primary Inhalation Methods
There are two fundamental ways to inhale vapor: Mouth-to-Lung (MTL) and Direct-to-Lung (DTL). Choosing the right one depends almost entirely on the type of device you are using and the specific e-liquid inside it.
Mouth-to-Lung (MTL) Inhaling
Mouth-to-Lung vaping is the most common technique for those using starter kits, pod systems, and high-resistance coils. In this method, you draw the vapor into your mouth first, hold it for a brief moment, and then pull it into your lungs.
MTL vaping feels very similar to the sensation of using a straw. Because the airflow on these devices is typically restricted, you must use a slow, steady pull rather than a sharp, aggressive one. This technique is preferred by vapers who value flavor precision and a noticeable "throat hit."
Best For:
- Beginners using starter kits.
- Compact pod systems (like those from SMOK or Vaporesso).
- High-nicotine e-liquids and nicotine salt e-liquids.
- Coils with a resistance of 1.0 ohm or higher.
Direct-to-Lung (DTL) Inhaling
Direct-to-Lung vaping, often called "Sub-Ohm" vaping, involves drawing the vapor directly into your lungs in one continuous breath. This is similar to taking a deep, natural breath or inhaling through a snorkel.
DTL devices feature wide-open airflow and low-resistance coils that produce significantly more vapor. Because the volume of vapor is much higher, DTL vaping typically requires e-liquids with lower nicotine concentrations—usually 3mg or 6mg—to avoid an overwhelming sensation.
Best For:
- Experienced vapers using box mods and sub-ohm tanks.
- Cloud chasing and maximum vapor production.
- Low-nicotine freebase e-liquids.
- Coils with a resistance below 1.0 ohm (sub-ohm).
Matching Your Hardware to Your Technique
To inhale correctly, your technique must match your hardware. Attempting to DTL a restricted pod system can cause the coil to burn out, while attempting to MTL a high-wattage sub-ohm tank often results in a hot, turbulent, and uncomfortable experience.
Pod Systems and Pens
Most vape pens and pod systems are designed for MTL inhalation. These devices use smaller coils with restricted air passages. When using these, your draw should be gentle. If you pull too hard, you may flood the coil, leading to "spit-back," which is when unvaporized e-liquid enters your mouth.
Box Mods and Sub-Ohm Tanks
Box mods are high-powered devices that allow you to adjust wattage and airflow. When using a sub-ohm tank (a tank with a coil resistance below 1.0 ohm), the device is built to move a large volume of air. These require a DTL inhale. You should open the airflow control ring at the base of the tank to at least 50% and take a deep, steady breath directly into your lungs.
The Role of E-Liquid in Inhalation
The composition of your e-liquid plays a massive role in how it feels when you inhale. Every e-liquid we carry at Vapor Authority is US-made and uses specific ratios of PG and VG.
PG vs. VG Ratios
- Propylene Glycol (PG): This is a thinner liquid that carries flavor effectively and provides the "throat hit." High PG liquids (50% or more) are best for MTL inhaling.
- Vegetable Glycerin (VG): This is a much thicker liquid responsible for creating large vapor clouds. High VG liquids (70% or more) are designed for DTL inhaling and sub-ohm devices.
Using a high-VG liquid in a small MTL pod system can lead to "dry hits" because the thick liquid cannot soak into the small coil fast enough. Conversely, using a high-PG liquid in a sub-ohm tank may cause leaking because the liquid is too thin for the large juice ports.
Nicotine Strength and Inhale Style
Nicotine strength must be balanced with your inhalation method.
- Nicotine Salts: These often come in 25mg to 50mg strengths. They should only be used with the MTL technique in low-wattage devices. Direct-to-lung inhaling high-strength salts can be extremely unpleasant.
- Freebase Nicotine: Standard freebase nicotine (3mg to 12mg) is versatile. 3mg and 6mg are the industry standard for DTL vaping, while 12mg and 18mg are better suited for MTL.
Step-by-Step: How to Inhale Correctly
How to Perform a Mouth-to-Lung (MTL) Inhale
- Check Your Airflow: Ensure your device airflow is set to a restricted setting.
- The Draw: Take a slow, steady pull of vapor into your mouth. Do not swallow it; let it linger in your oral cavity for a second.
- The Inhale: Open your mouth slightly and draw a fresh breath of air, pulling the vapor down into your lungs.
- The Exhale: Exhale the vapor immediately. There is no need to hold it in like other substances; nicotine absorption happens almost instantly in the membranes of the mouth and lungs.
How to Perform a Direct-to-Lung (DTL) Inhale
- Check Your Airflow: Ensure your tank’s airflow is fully open or at least half-open.
- The Draw: Place your lips on the drip tip and take a deep, fast breath directly into your lungs. Think of it like taking a deep breath of fresh air.
- The Exhale: Exhale the vapor immediately. Because the volume is higher, you will see much larger clouds.
Avoiding Common Inhalation Mistakes
Even experienced vapers can run into issues if their technique slips. Here are the most common problems and how to fix them.
Why Am I Coughing?
Coughing is common for beginners, but it is usually a sign that something is slightly off.
- Wrong Nicotine Level: If the nicotine is too high for your device, it will feel harsh.
- Old Coil: A "burnt" coil produces acrid vapor that irritates the throat.
- The "Double Inhale": Sometimes vapers try to inhale, stop, and then inhale again. This can cause the vapor to settle and irritate the throat. Use one smooth motion.
Preventing Burnt Hits and Priming
A "dry hit" occurs when the cotton inside your coil is not saturated with e-liquid. To avoid this, you must "prime" your coil.
- How to Prime: Before installing a new coil, drip 3-5 drops of e-liquid directly onto the exposed cotton. Once the tank is filled, let it sit for 5-10 minutes before your first inhale.
- Primer Puffs: Take a few short "puffs" without hitting the firing button to help pull liquid into the cotton.
Managing Chain Vaping
Inhaling too frequently in a short period is known as chain vaping. This can lead to the coil overheating or the cotton drying out before it has a chance to re-saturate. Give your device 15-30 seconds between inhales to ensure the coil stays cool and wet.
Battery Safety for Hardware Users
If you are using a device that requires external batteries (like 18650 or 21700 cells), proper safety is non-negotiable. Your inhalation experience is only as good as the safety of your power source.
- Inspect Your Wraps: Never use a battery if the plastic "wrap" has a tear, nick, or scratch. This can cause a short circuit.
- Use a Dedicated Case: Never carry loose batteries in your pocket or bag. They can contact metal objects like keys or coins and vent. Always use a plastic battery case.
- Correct Charging: While many mods support USB charging, we recommend using an external "smart" charger. This ensures your batteries are balanced and prevents overcharging.
- Matched Pairs: If your mod takes two batteries, use a "married" pair—two batteries of the same brand and model that are always used and charged together.
Advanced Techniques for Enthusiasts
Once you are comfortable with basic inhalation, you can experiment with airflow and wattage to fine-tune your experience.
Adjusting Airflow
Most modern tanks allow you to "dial in" the draw. Closing the airflow increases the temperature of the vapor and intensifies the flavor. Opening the airflow cools the vapor and increases cloud production. Finding your "sweet spot" is a matter of trial and error.
Temperature Control (TC)
Some advanced box mods offer Temperature Control mode. This allows you to set a specific temperature for your coil (using stainless steel, nickel, or titanium wire). This prevents the coil from ever getting too hot, virtually eliminating the possibility of a burnt inhale.
Maintaining Your Device for Better Inhalation
A dirty device leads to a poor inhale. E-liquid can build up in the "chimney" or under the drip tip, leading to a gurgling sound or liquid entering your mouth.
- Clean the Drip Tip: Remove the mouthpiece and rinse it with warm water daily.
- Wipe the Connection: Use a paper towel to clean the 510 connection (where the tank meets the mod) to ensure a strong electrical current.
- Replace Coils Regularly: Most coils last between one and two weeks. Once the flavor starts to mute or you notice a slight "singed" taste, it is time for a fresh one.
Conclusion
Mastering how to inhale a vape pen is the foundation of a rewarding experience. By identifying whether you prefer the restricted, flavor-focused Mouth-to-Lung style or the airy, cloud-heavy Direct-to-Lung style, you can choose the hardware and e-liquids that match your preferences.

FAQ
Why am I coughing when I inhale my vape pen?
Coughing is usually caused by using a nicotine strength that is too high for your device or using a Direct-to-Lung technique on a device meant for Mouth-to-Lung. It can also happen if your coil is old and needs to be replaced, as burnt cotton is highly irritating to the throat.
What is the difference between MTL and DTL?
MTL (Mouth-to-Lung) involves drawing vapor into your mouth first and then inhaling it into your lungs, similar to how you would use a straw. DTL (Direct-to-Lung) involves breathing the vapor directly into your lungs in one deep breath, which produces much larger clouds and requires lower nicotine levels.
Can I use nicotine salts for direct-to-lung vaping?
It is generally not recommended to use high-strength nicotine salts (25mg-50mg) for DTL vaping. The high volume of vapor produced in DTL setups can deliver too much nicotine at once, leading to a very harsh throat hit and potential discomfort.
How long should I hold the vapor in my lungs?
Unlike other substances, there is no benefit to holding vape vapor in your lungs for an extended period. Nicotine is absorbed almost immediately upon inhalation. Holding it in for too long can actually cause unnecessary throat irritation without increasing the satisfaction of the session.
