What Is Mouth To Lung Vaping?
A clear UK guide to mouth to lung vaping, the technique that mimics smoking and why most UK ex smokers start with this style.
MTL means drawing vapour into your mouth first, then inhaling to your lungs.
It is the two stage technique smokers use with cigarettes. Vapour fills the mouth briefly, then a second breath takes it to the lungs. MTL devices are small, low powered and use higher nicotine strengths. Most UK ex smokers start with MTL because it feels familiar and effective for nicotine satisfaction.
MTL is the bedrock of UK vape success for ex smokers. The technique mimics cigarettes precisely. The devices are small enough to use anywhere. The nicotine strengths satisfy heavy smokers from day one. Understanding why MTL works helps you avoid the common mistake of jumping to DTL too soon.
What makes MTL different from DTL
Four core differences shape the experience. The grid below covers each.
Two stage inhale
Vapour to mouth first, brief hold, then to lungs. Same as cigarettes.
✓ Cigarette likeLow power
MTL devices run 10 to 25W. Far less than sub ohm DTL devices.
✓ DiscreetHigher nicotine
MTL uses 10 to 20mg salt nicotine or 6 to 18mg freebase. Cigarette equivalent strength.
✓ Strength matchLess vapour
Smaller clouds similar to cigarette smoke. Discreet for public use.
✓ Less visibleWhy MTL suits ex smokers
The table below covers why MTL is the standard recommendation for UK switchers.
| Smoker need | How MTL meets it |
|---|---|
| Familiar inhale technique | Same two stage draw as cigarettes |
| Strong throat hit | Higher nicotine strength delivers cigarette like sensation |
| Quick nicotine satisfaction | 20mg salts peak in blood within 1 to 3 minutes |
| Low cost entry | MTL devices 15 to 50 pounds compared with mod kits 60 to 200 |
| Discreet appearance | Small devices that look less obvious than mods |
| Less complex setup | No wattage adjustment needed on most MTL devices |
Common UK MTL device types
Three categories cover most UK MTL setups. Pod systems with prefilled or refillable pods (such as the Vaporesso XROS), basic MTL tanks paired with simple battery devices (such as the Innokin Endura), and starter mod kits with adjustable wattage but used at MTL settings (such as some Smok kits). Most UK vape shops have dedicated MTL displays. Asking shop staff for ex smoker recommendations almost always points to MTL options.
UK Stop Smoking Services overwhelmingly recommend MTL vaping for switchers. The service guidance is based on success rate research showing MTL has higher cigarette quit rates than DTL for first time switchers. Some local services provide MTL starter kits free or at subsidised cost. Asking your GP or local pharmacy can identify whether your area has this scheme.
How to use MTL technique correctly
The checklist below covers what UK vape shop staff most often recommend.
MTL technique checklist
Use four or more of these for satisfying MTL vaping.
- Take slow gentle puffs of 2 to 3 seconds
- Hold vapour briefly in your mouth
- Inhale to your lungs as a second breath
- Exhale through nose or mouth as preferred
- Avoid taking long deep draws like DTL technique
- Match nicotine strength to your previous cigarette habit
When MTL might not suit you
MTL is the standard recommendation for ex smokers but not everyone gets on with it. If MTL feels unsatisfying after weeks of practice, the issue is usually nicotine strength rather than the style. Try moving up to 20mg salts before considering DTL. Some UK vapers naturally prefer the smoothness of DTL but they typically need to use much lower nicotine which then fails to satisfy heavy ex smokers. MTL is the right starting point for most.
MTL is the partner style to DTL, which our our guide on what is direct to lung vaping covers in detail, plus our article on MTL vs DTL vaping explained covers the prefilled pod systems that are MTL by default.
