Users employ different methods of inhaling vapor based on their preference and the specific device they are using. The Mouth-to-Lung (MTL) technique is one of the two main inhalation methods, defined by a two-step process that closely mirrors smoking a traditional cigarette. Understanding this technique is often the first step for individuals transitioning from smoking to vaping.
Defining the Mouth-to-Lung Technique
Mouth-to-Lung is an inhalation style where the vapor is first drawn from the device and held momentarily within the oral cavity before being fully inhaled into the lungs. The action begins with a steady, gentle draw on the mouthpiece, allowing a concentrated amount of vapor to accumulate in the mouth. This step requires restricted airflow, similar to sipping through a straw.
After the vapor has collected, the user inhales deeply, pulling the vapor from the mouth down into the lungs in a second distinct movement. This final inhalation often involves drawing in an additional breath of fresh air to clear the vapor and guide it into the respiratory system. This two-part action gives the technique its name and provides a familiar sensation for those accustomed to smoking.
Key Differences from Direct-to-Lung Vaping
The Mouth-to-Lung method is characterized by a significantly restricted airflow, which is a major point of difference from the alternative Direct-to-Lung (DTL) technique. With MTL, the draw feels tight, similar to the drag on a conventional cigarette, whereas DTL utilizes a much looser, more open airflow.
This restricted design results in a lower volume of vapor production, making MTL a more discreet option that produces smaller clouds. The experience of the vapor resting in the mouth also allows for a more pronounced flavor perception before it reaches the lungs.
Another key distinction is the sensation upon inhalation, commonly referred to as the throat hit. MTL vaping delivers a more concentrated and often stronger throat hit, especially when using higher nicotine concentrations. Conversely, the DTL technique involves a large, continuous inhale directly into the lungs, resulting in a smoother, less intense sensation with lower nicotine e-liquids.
Ideal Equipment for MTL
Achieving an effective Mouth-to-Lung draw relies on specific hardware configurations designed to restrict the vapor path and manage power output. MTL devices typically utilize coils with a higher electrical resistance, generally specified at 1.0 ohm (\(\Omega\)) or above. This higher resistance is necessary to prevent the coil from overheating at the lower power settings required for this technique.
The higher-resistance coils are paired with a significantly lower wattage range, typically operating between 8 and 20 Watts (W). This low power usage generates a cooler, less voluminous vapor that is ideal for the two-step inhalation process.
Furthermore, the physical design of MTL tanks and pods often includes a much narrower mouthpiece, or drip tip, and smaller airflow apertures. These features physically enforce the restricted draw needed to mimic the feel of a cigarette.
Why Choose Mouth-to-Lung
The primary appeal of the Mouth-to-Lung technique is its familiarity to individuals transitioning from combustible cigarettes, as the action and sensation closely replicate traditional smoking. This provides a satisfying and intuitive experience for new vapers, making the switch less daunting.
The restricted airflow and coil configuration also contribute to enhanced flavor delivery, as the vapor lingers in the mouth before the final inhalation, allowing the taste buds to register the e-liquid’s profile more fully.
Beyond the user experience, MTL vaping offers practical benefits related to operational efficiency and discretion.
The lower wattage settings and smaller vapor production mean that the device consumes significantly less e-liquid and battery power compared to high-power DTL setups. This efficiency translates to lower running costs, and the minimal vapor clouds allow for a more discreet use in public settings.
