Using nic salts is straightforward once you have the right device and understand the basics. This step-by-step guide covers everything from choosing your pod kit and strength through to filling, priming and vaping correctly for the best experience.
Quick Answer: To use nic salts, fill a refillable MTL pod kit with a 50/50 nic salt e-liquid at your chosen strength (5mg, 10mg or 20mg), wait five minutes for the coil to saturate, then draw on the device slowly as you would a cigarette: vapour into the mouth first, held briefly, then inhaled into the lungs. Most pod kits are draw-activated and fire automatically. The correct device is a low-wattage MTL pod kit with a coil above 0.8ohm running at 8W to 18W. Nic salts are not for use in sub-ohm or high-wattage DTL devices.
Nic salts are designed for low-wattage MTL (mouth-to-lung) pod kits. These are compact, refillable devices with coils rated at 0.8ohm to 1.2ohm that operate at 8W to 18W. The tight, restricted draw they produce mimics a cigarette and keeps nicotine delivery controlled at 10mg and 20mg strengths.
The most widely recommended pod kits for nic salts in the UK in 2026 include the Vaporesso XROS series, OXVA Xlim series and Uwell Caliburn series. All are compact, straightforward to fill and use. They produce excellent flavour from standard 50/50 nic salt e-liquids. Most have draw-activated firing, meaning you simply inhale to activate the device with no button pressing required.
Do not use nic salts in sub-ohm tanks, high-wattage box mods or any DTL (direct-to-lung) setup. The volume of vapour these devices produce at high wattage delivers dangerously excessive nicotine per puff from 10mg or 20mg nic salts.
UK nic salts are available in three standard strengths. Choosing the right one from the start makes the switch from cigarettes much smoother and reduces the likelihood of headaches or unsatisfied cravings.
| Strength | Best For | Typical Use |
|---|---|---|
| 20mg | Heavy smokers (20+ cigarettes/day); recent ex-disposable users | Fewer puffs per session; strong craving satisfaction |
| 10mg | Moderate smokers (10 to 20/day); stepping down from 20mg | More puffs per session; slightly lighter throat hit |
| 5mg | Light smokers; established vapers stepping down further | Flavour-forward vaping; minimal throat hit |
If you are unsure, start at 20mg. This is the UK legal maximum and is the strength that most closely replicates the nicotine satisfaction of a cigarette. You can always step down to 10mg once your cravings are consistently managed. Starting too low and not satisfying cravings is the most common reason people revert to smoking when attempting to switch.
Most refillable pod kits fill from the side or bottom of the pod rather than the top. Look for a rubber bung, a silicone plug or a small covered port. Remove or slide open the cover. Some pods have a top-fill design where the mouthpiece lifts to reveal the fill port. Check your device manual if you are unsure which method your pod uses.
UK nic salt bottles have childproof caps that require a push-and-turn motion to open. Place the bottle on a flat surface, press the cap firmly downward and twist anticlockwise simultaneously. If the cap spins without releasing, you are not pressing hard enough. Apply more downward force while twisting. The cap will release after one to two full turns under sufficient pressure. For the squeeze and pour method, see our separate guide on How to Open a Nic Salt Bottle.
Tilt the pod at a slight angle and insert the fine nozzle tip of the nic salt bottle into the fill port. Squeeze the bottle gently to release e-liquid. Fill to just below the maximum fill line marked on the pod. Do not overfill. Most UK pods hold 2ml of e-liquid, the TRPR maximum. Replace the rubber bung or close the fill port cover firmly after filling.
After filling, wait at least five minutes before taking your first puff. This allows the e-liquid to fully saturate the cotton wicking material inside the coil. Vaping immediately on a dry or partially saturated coil causes the dry cotton to burn on the first draw, permanently damaging the coil and producing an unpleasant burnt taste that does not improve with further use. Five minutes of waiting prevents this entirely.
The drawing technique for nic salts is mouth-to-lung (MTL). This is the same technique as smoking a cigarette and is what nic salts and MTL pod kits are specifically designed for.
Draw the vapour slowly into your mouth over two to three seconds, the same way you would draw on a cigarette. Hold the vapour in your mouth briefly for one to two seconds, then inhale it into your lungs. Exhale slowly. The puff should feel controlled and satisfying. On most draw-activated pod kits there is no button to press: simply inhale through the mouthpiece to activate the device.
Do not take a long, deep direct-to-lung inhale as you would with a sub-ohm device. This delivers more vapour than an MTL pod is designed to produce and can result in flooding the coil or excessive nicotine intake. Do not chain vape: allow five to ten seconds between puffs to let the wick resaturate. Do not hold the device upside down while vaping, as this can cause e-liquid to flood the coil.

Our complete guide library covers every nic salt question for UK vapers. Strengths, devices, safety, comparisons and more.
Yes. Charge your pod kit fully before first use. A depleted or low battery does not heat the coil consistently, which results in weak vapour, poor flavour and an unsatisfying nicotine hit. Most modern pod kits use USB-C charging and reach a full charge within 45 to 90 minutes. A fully charged device gives the coil the consistent power it needs to vaporise nic salt e-liquid correctly from the first puff.
There is no fixed number. A useful guideline for 20mg nic salts is three to five puffs per session and then a pause of at least 10 to 15 minutes before vaping again. This allows the nicotine to absorb and take effect before you assess whether your craving is satisfied. Taking many rapid puffs without pausing is the most common cause of headaches and nausea among new nic salt users.
Most pods have a transparent window that lets you see the e-liquid level. When the level drops close to the bottom wicking ports on the coil, refill immediately. Vaping with the pod running almost dry causes the cotton to burn, producing a harsh taste and damaging the coil permanently. The first sign of a near-empty pod is usually a slightly harsh or muted flavour compared to when the pod was full.
