DL inhalation

    DL inhalation

    « Back to Glossary Index

    Direct Lung (DL) inhalation is generally opposed to Mouth to Lung (MTL) vaping.

    With this technique, the user inhales the vapor straight down into the lungs, like when taking a deep breathe. This method is commonly associated with sub-ohm vaping, when a larger amount of vapor is produced.

    The technique is suited to experienced vapers and provides a more intense hit. It is associated with mods offering subohm characteristics with low resistance coils (<1.0 Ω), high power (>30 W) and a wide drip-tip also referred to as drip-top. It requires rapid inhalation of the vaporized e-liquid at higher temperature than MTL. The throat hit is more intense so e-liquids may contain less PG, more VG and low nicotine strength (between 0 and 7 mg/ml). Experienced vapers dilute e-juices with pure VG to compensate for more intense throat hit.

    The “+”:

    • More powerful than MTL
    • Produces bigger clouds
    • Allows vape tricks and cloud chasing

    The “-“:

    • Uses more juice
    • Adds risks:
      • Hot vapor is more aggressive to epithelial cells,
      • Requires lower PG and nicotine strength to avoid harsh throat hits
      • Needs regulated temperature and watch juice supply to avoid dry burns.
    • Less relaxed and casual than MTL
