Mouth To Lung (MTL) vs. Direct To Lung (DTL) Vaping

Mouth To Lung (MTL) vs. Direct To Lung (DTL) Vaping

Mouth To Lung (MTL) vs. Direct To Lung (DTL) Vaping

Vaping has become a popular alternative to smoking, offering a variety of styles and methods to suit different preferences. Two primary vaping techniques are Mouth To Lung (MTL) and Direct To Lung (DTL). Understanding the differences between these methods, along with the role of subohm coils and the impact of coil resistance and strength on e-liquids, can help you make an informed choice.

Mouth To Lung (MTL) Vaping

What is MTL Vaping?

MTL vaping mimics the traditional smoking experience. The process involves drawing vapor into the mouth first and then inhaling it into the lungs. This technique is similar to how most people smoke cigarettes, making it a popular choice for those transitioning from smoking to vaping.

Characteristics of MTL Vaping

  • Tighter Draw: MTL devices typically have a more restricted airflow, providing a tighter draw that simulates the sensation of smoking a cigarette.
  • Higher Nicotine Levels: Since MTL vaping produces less vapor, it is often paired with e-liquids containing higher nicotine concentrations (e.g., 12mg/mL or higher) to deliver a satisfying nicotine hit.
  • Flavor Intensity: MTL vaping generally enhances the flavor of e-liquids, as the slower, more deliberate draw allows for better flavor absorption.
  • Lower Vapor Production: MTL devices produce less vapor compared to DTL setups, making them more discreet and suitable for public places.

Direct To Lung (DTL) Vaping

What is DTL Vaping?

DTL vaping involves inhaling vapor directly into the lungs without holding it in the mouth first. This method is often favored by experienced vapers seeking a more intense experience and larger vapor clouds.

Characteristics of DTL Vaping

  • Airier Draw: DTL devices have more open airflow, providing a looser draw that allows for a larger volume of vapor to be inhaled directly into the lungs.
  • Lower Nicotine Levels: Because DTL vaping produces more vapor, e-liquids with lower nicotine concentrations (e.g., 3mg/mL or 6mg/mL) are commonly used to prevent an overly harsh throat hit.
  • Cloud Production: DTL setups are known for producing significant vapor clouds, making them popular among cloud-chasing enthusiasts.
  • Subtle Flavor: While DTL vaping can still provide good flavor, the emphasis on vapor production sometimes means that flavor nuances are less pronounced compared to MTL vaping.

The Role of Subohm Coils

What are Subohm Coils?

Subohm coils have a resistance of less than 1 ohm (Ω). These coils are designed to work at higher wattages and produce more vapor, making them ideal for DTL vaping.

Advantages of Subohm Coils

  • Enhanced Vapor Production: Subohm coils generate more vapor due to their lower resistance and higher power output.
  • Improved Flavor: While flavor can be subjective, many vapers find that subohm coils provide a richer and more intense flavor profile.
  • Increased Airflow: Subohm tanks and devices are designed to accommodate the increased airflow required for these coils, contributing to the overall DTL experience.

Impact of Coil Resistance and Strength on E-Liquids

Coil Resistance

  • Low Resistance (<1Ω): Subohm coils with low resistance are suitable for high-wattage devices. They produce more vapor and require e-liquids with lower nicotine strengths to avoid harsh throat hits. A lot of newer pod style devices are now using lower resistance coils in the MTL style to increase flavour and offer a better all round vaping experience.
  • High Resistance (>1Ω): Coils with higher resistance are typically used in MTL devices. They are suitable for e-liquids with higher nicotine concentrations and provide a tighter draw and more pronounced flavor.

Coil Strength and Durability

  • Material and Build: Coil materials (e.g., kanthal, stainless steel, nickel) and build quality affect their longevity and performance. High-quality coils tend to last longer and provide a consistent vaping experience.
  • Wicking Material: The type of wicking material (e.g., cotton, ceramic) can influence flavor and vapor production. Proper wicking ensures efficient e-liquid absorption and minimizes dry hits.

E-Liquid Composition

  • PG/VG Ratio: The ratio of Propylene Glycol (PG) to Vegetable Glycerin (VG) in e-liquids can impact the vaping experience. Higher PG ratios (e.g., 70/30) are often used in MTL setups for a stronger throat hit and better flavor, while higher VG ratios (e.g., 30/70) are preferred in DTL setups for smoother vapor and bigger clouds.
  • Nicotine Salts vs. Freebase Nicotine: Nicotine salts provide a smoother throat hit at higher concentrations, making them ideal for MTL devices. Freebase nicotine is commonly used in lower concentrations for DTL vaping.

What is right for me?

Choosing between Mouth To Lung (MTL) and Direct To Lung (DTL) vaping depends on personal preferences and desired experiences. MTL vaping offers a familiar, cigarette-like draw with higher nicotine levels and intense flavor, making it ideal for beginners and those seeking a discreet vaping experience. DTL vaping, on the other hand, provides an airier draw, larger vapor clouds, and is often paired with subohm coils for enhanced vapor production.

Understanding the role of coil resistance and strength, along with the composition of e-liquids, can further refine your vaping experience. Whether you prefer the tight, flavorful draws of MTL or the cloud-chasing potential of DTL, there is a setup to match your needs. Happy vaping!
