Lung Hit – What is it in Vaping?
Definition
A lung hit is a style of vaping where the vapour is inhaled directly into the lungs in one smooth, continuous draw, bypassing the mouth-hold stage typical of “mouth-to-lung” (MTL) vaping. Designed to mimic the sensation of taking a deep breath, lung hits maximise vapour volume, flavour intensity and nicotine delivery, making them popular among cloud-chasers and former smokers seeking a stronger “throat hit”. Beginners often graduate to lung hits once they feel comfortable with basic device operation and e-liquid ratios.
Technical Details
Lung-hit capability depends on low-resistance coils (usually ≤ 0.6 Ω), high-wattage output (40–120 W) and wide-bore drip tips that reduce air-flow restriction. Devices are configured for DL (direct-lung) airflow, measured in cubic millimetres of air per second (mm³/s). Most sub-ohm tanks and rebuildable atomisers use adjustable airflow rings with 2–8 mm inlet slots. E-liquid ratios favour high-VG blends (70/30 or 80/20 VG/PG) to produce dense vapour without harsh throat sensation. Battery Safety”>Battery safety is critical: high-drain lithium batteries rated ≥ 20 A continuous discharge are recommended to prevent overheating.
Usage & Tips
- Start low: Begin at 40 W and increase in 5 W steps until flavour peaks without dry hits.
- Wicking: Ensure cotton is fluffy and fully saturated to avoid leaking or burnt taste.
- Watch the LED indicator: Rapid flashing often signals Resistance“>low resistance or battery strain—pause and check coil specs.
- Safety: Never exceed the battery’s amp limit; use married pairs in dual-battery mods.
- Ratio matters: Stick to 70 % VG or higher for smooth lung hits; thinner liquids may flood coils and leak.
History & Context
Lung hits gained traction around 2014 when sub-ohm tanks like the Aspire Atlantis paired with high-capacity lithium batteries let vapers safely push past 30 W. Australian cloud-chasing comps soon adopted the style, cementing lung hits as the benchmark for flavour and vapour production.
