What is mouth to lung vaping?

How the technique works

MTL has three parts. The technique is intuitive for ex-smokers because it is the same as cigarette smoking.

1. Draw vapour into your mouth

   Take a slow 2-3 second pull. Vapour collects in your mouth (cheek puff). You should taste the flavour clearly at this stage.

2. Hold briefly

   Pause for half a second to a second with the vapour in your mouth. This is the “mouth” part of mouth to lung. Some experienced MTL vapers skip this step.

3. Inhale into the lungs

   Open your throat and breathe the vapour down. This is the “to lung” part. Exhale through nose or mouth.

If you can remember how you used to draw on a cigarette, you already know MTL technique. It is the same motion. This is why MTL kits are usually recommended to people transitioning from smoking.

What MTL feels like

• Draw resistance: Tight. Similar effort to drawing on a cigarette. Should not feel free-flowing.
• Vapour volume: Modest. Discreet clouds, not the big plumes from sub-ohm devices.
• Flavour intensity: Concentrated. Because vapour is held in the mouth first, flavour registers strongly before inhalation.
• Throat hit: Strong. The combination of higher nicotine and the cheek-pause delivers a noticeable hit in the throat similar to a cigarette.
• Vapour temperature: Cooler. Low wattage means cooler vapour than DTL.
• Battery life: Long. Low wattage means less power draw. A typical MTL pod kit lasts a full day of moderate use on one charge.

The right kit for MTL

MTL kit is generally smaller, simpler and cheaper than DTL kit. Most UK starter kits in 2026 are MTL or have an MTL mode.

What to look for in an MTL kit:

• Wattage range 8-25W: Higher than this and you are heading toward DTL territory.
• Coil resistance 1.0 ohm or higher: Lower resistance coils produce more vapour than MTL needs.
• Tight airflow: A small airflow hole or adjustable airflow that can close down. Some pod kits have fixed tight airflow ideal for MTL.
• Small tank capacity: 2ml is the UK legal limit. MTL devices use less liquid per puff than DTL, so a 2ml tank lasts a typical day.

The right e-liquid for MTL

E-liquid choice matters more for MTL than most beginners realise. The wrong liquid in an MTL coil produces flooding, weak vapour and poor flavour.

The nicotine strength question

Nicotine strength matters more in MTL than DTL because the throat hit is essential to the MTL experience. Most ex-smokers find that MTL with 20mg salt nicotine closely matches the satisfaction of a cigarette.

• Heavy smokers (20+ a day): Start with 20mg nic salts MTL. The standard UK starting point.
• Moderate smokers (10-20 a day): 10mg to 20mg nic salts work well. Try 20mg first; drop to 10mg if too strong.
• Light smokers (under 10 a day): 10mg nic salts. Sometimes 6mg freebase if MTL feels too strong.
• Social smokers or wanting to reduce: 6mg freebase or 10mg salt. Adjust over time.
• Heading down to zero: Step down gradually: 20mg, 10mg, 6mg, 3mg, 0mg. Most ex-smokers take 3-6 months to comfortably reach 0mg.

Who MTL suits best

MTL is the default style for most UK vapers. It suits a wide range of users for several reasons.
