Nasty Liq Nic Salts 10ml 20mg at a glance

Nasty Liq Nic Salts by Nasty Juice 10ml 20mg is a nicotine salt e-liquid sold in a 10ml bottle at a strength of 20mg/ml, which is 2% nicotine by volume. It is a ready-to-use liquid for refillable pod kits and low-wattage devices. It is not a disposable and it is not a sealed pod: you open the bottle, fill the tank or pod of a compatible kit, and vape. This listing covers the Nasty Liq range at 20mg, with thirteen flavour variants to choose between, so you pick your flavour from the selector on the page and the same strength and bottle size apply throughout.

The flavours in the range are Berry Bull, Blue Bangs, Blue Raspberry, Blueberry Raspberry Lemonade, Blueberry Sour Raspberry, Cherry Ice, Fizzy Cherry, Gummy Bear, Mango Peach and Pineapple, Menthol, Mineral Water, Peach Ice and Pineapple Ice. Between them they cover sweet candy fruit, sharp sour fruit, iced fruit, plain menthol and a very light, clean option, which means most adult vapers who like a fruit or menthol profile will find something that suits.

The key facts in plain terms:

• Bottle size: 10ml, which is the largest size UK rules allow for a liquid that contains nicotine.
• Nicotine strength: 20mg/ml, the maximum permitted in the UK. A full bottle holds 200mg of nicotine in total.
• Nicotine type: nicotine salt, which feels smoother at high strength than the freebase nicotine used in most larger bottles.
• Intended hardware: refillable pod kits and low-power tank devices, usually running coils between about 0.6 and 1.2 ohm at roughly 8 to 25 watts.
• Vaping style: mouth-to-lung or a loose, restricted draw, not the big open airflow of a sub-ohm tank.
• Who can buy it: adults aged 18 or over only, and it is intended for people who already use nicotine.

Nasty is a familiar name in the UK e-liquid market, and the Nasty Liq line takes that flavour-first approach into the 10ml nic salt format. Nothing here is a miracle or a shortcut. It is a straightforward, sensibly sized bottle of salt nicotine liquid for people who want a flavoured refill for a pod kit, and the rest of this guide explains how it behaves, what it pairs with, and where it fits against the alternatives so you can decide without guesswork.

Nic salts explained and how to think about 20mg strength

Nicotine salt liquid, usually shortened to nic salt, uses a different form of nicotine from the freebase nicotine found in most shortfills and nicotine shots. A small amount of acid, commonly benzoic acid, is added so that the nicotine is bound in a more acidic, lower pH form. The practical result is that the throat hit is noticeably gentler at a given strength. That matters because nic salt liquids are made at much higher strengths than freebase liquids, and a freebase liquid at 20mg/ml would feel harsh to nearly everyone.

The second difference is how quickly nicotine reaches the bloodstream. Nic salts are generally reported to deliver nicotine more quickly and steadily than freebase at the same strength, which is why many people who are stepping away from cigarettes find salts a closer match for the habit. It also explains why they are used in low-power devices: you do not need a big cloud to get the nicotine, so small batteries and tight coils do the job.

Understanding 20mg/ml. The number on the bottle is milligrams of nicotine per millilitre of liquid. At 20mg/ml, each millilitre carries 20mg, so a 10ml bottle contains 200mg in total. A typical 2ml pod filled with it holds about 40mg. Because UK rules cap e-liquid at 20mg/ml, this is the strongest nicotine liquid you can lawfully buy here. The same ceiling used to apply to prefilled pods and, before they were withdrawn from sale, to disposable vapes.

Is 20mg right for you? It is the top of the range, not the default. As a rough guide:

• 20mg/ml suits people who smoke around 10 or more cigarettes a day, or who feel unsatisfied on lower strengths and find themselves constantly topping up.
• 10mg/ml to 12mg/ml suits lighter smokers or people who want a gentler experience with the same salt smoothness.
• 5mg/ml to 6mg/ml suits people who are winding down and want a very light hit.

If you have never used nicotine, this strength is not for you. If you are moving from smoking and want a lower strength than this listing offers, look for the 10mg versions of similar products instead of diluting this one yourself. Salt nicotine is very easy to overdo at 20mg, and signs of too much include light-headedness, nausea, a racing heart or a headache. If that happens, stop, take a break, and drop to a lower strength next time. Remember too that smoking and vaping have different feels, and it can take a week or two to settle on the strength that works.

The Nasty Liq flavour range and how to choose

Because this single listing covers thirteen variants, the biggest decision is flavour. The names give a good indication of what to expect, and grouping them by style makes the choice easier. Flavour descriptions below are based on what each name and its category usually mean in nic salt liquids, so treat them as a guide to the direction of travel rather than an exact recipe.

• Sweet candy and confectionery: Gummy Bear and Berry Bull sit here. Expect a rounded, sugary profile with a soft fruit character, built for people who like a sweet vape.
• Sharp and sour fruit: Blueberry Sour Raspberry, Fizzy Cherry and Blue Bangs lean towards tangy, slightly bright flavours with a sour edge that cuts through the sweetness.
• Blended fruit and lemonade: Blueberry Raspberry Lemonade and Mango Peach and Pineapple combine several fruits, giving a layered flavour that changes a little from first draw to exhale.
• Single fruit: Blue Raspberry is the straightforward, familiar blue-sweet profile that many UK vapers know from the disposable era.
• Iced fruit: Cherry Ice, Peach Ice and Pineapple Ice add a cooling finish to a single fruit. The cooling is meant to be refreshing, not harsh.
• Cooling and clean: Menthol is the classic option for people who want a straightforward cool vape, and Mineral Water is the lightest, least sweet choice in the line.

How to choose. If you are unsure, consider what you enjoyed before. People moving away from cigarettes often start with menthol or a simple iced fruit because the flavours feel closer to a habit they know. People who want something fun and sweet usually go for the candy and berry options. If you have a sensitive throat, an iced or menthol flavour can feel crisper, so a sweet fruit with no cooling may be easier to start with.

A word on mixing and trying new ones. A 10ml bottle is a modest commitment, so it is reasonable to try a couple of flavours before settling. Flush the pod or tank and let the device dry for a few minutes before switching flavour, because old flavour lingers in the cotton and can muddy the new one. Do not mix different liquids in one tank unless you are comfortable experimenting, since combinations can taste flat or oddly sharp, and you will not be able to rely on the flavour you chose.

For variety, many people buy two bottles in contrasting styles, for example one sweet and one iced, and swap between them depending on mood. This is also a good way to protect against flavour fatigue, where a favourite taste starts to fade after several days of constant use.

Flavour profile and throat hit

Nic salt liquids behave differently from freebase juices on the palate. The lower pH and the way salts are formulated mean that flavour arrives in a smooth, rounded way instead of a sharp spike. At 20mg/ml you will still feel the nicotine in the back of the throat and chest, but it is a softer sensation than a freebase liquid of a similar strength would give. Many people describe it as a firm but clean hit that does not scratch.

With the Nasty Liq range, flavour-first is the priority. The fruit and candy options are written to give a clear top note on the inhale, a middle of sweetness or sourness, and a lingering aftertaste on the exhale. The iced variants add a cool finish that sits behind the fruit instead of overwhelming it, and Menthol puts the cooling at the front. Mineral Water is the exception, being a restrained, light profile with much less sweetness and no heavy fruit body.

What affects how flavour tastes in your device:

• Coil temperature. Low power keeps flavours crisp and true. Turning the wattage up tends to dull subtle notes and can add a slightly burnt edge, particularly with sweeter liquids.
• Coil age. A fresh coil gives the cleanest flavour. As sugar and flavouring residue builds on the coil, tastes flatten and sweet liquids can take on a caramelised, muted quality.
• Airflow. A tighter draw concentrates flavour and throat hit, while an airier draw spreads it out and feels cooler and lighter.
• Liquid temperature. Warm vapour makes sweet flavours richer, cooler vapour makes iced and menthol flavours feel sharper.

Sweetness level. Candy-style and berry flavours in this category tend to be sweet. If you vape a very sweet flavour all day, you may notice coils wearing out faster, because sweeteners caramelise on the coil. Many people rotate a sweet flavour with a lighter one such as an iced fruit or Mineral Water to keep their coils lasting and their palate fresh.

Tasting notes in practice. A good way to judge a nic salt flavour is to take a few short, slow draws and pay attention to three things: what you taste on the inhale, how the flavour changes on the exhale, and whether the aftertaste is pleasant or cloying after a minute. If the aftertaste feels too heavy, a lighter or iced flavour will probably suit you better in the long run. Everybody’s palate differs, so use these descriptions as signposts and trust your own experience once the bottle is open.

Performance and vapour delivery

A 10ml nic salt bottle is a liquid, not a device, so performance depends on what you pair it with. What the liquid itself brings is a nicotine-forward, low-vapour, flavour-focused experience. Nic salt formulations in this style are typically built on a balanced propylene glycol and vegetable glycerine base. A higher proportion of PG carries flavour and throat hit, while VG adds vapour density. Check the label on your bottle for the exact split, because it affects how the liquid wicks and how much vapour you see.

Here is what to expect in normal use:

• Vapour production. Modest. Salts are designed to be used in small, efficient devices, so the clouds are smaller than you get from a sub-ohm tank. Most people consider that a feature, because it is more discreet and uses less liquid.
• Nicotine delivery. Quick and consistent. A few draws are typically enough to feel satisfied, and the satisfaction tends to arrive early in the session instead of building slowly.
• Flavour intensity. Strong for the volume of vapour, because the coil is working at lower temperatures and the flavour is not diluted by large airflow.
• Throat hit. Smooth but present at 20mg. It is noticeably firmer than a 10mg salt but gentler than the same strength in freebase.

Consumption and how long a bottle lasts. A 10ml bottle fills a typical 2ml pod about five times. Usage varies a lot. A lighter user might take a week and a half or more to finish a bottle, while a heavy user replacing a pack-a-day habit could get through it in three to five days. Because nic salts deliver nicotine quickly, many people find they take fewer draws than they expected, and consumption settles after the first week.

Consistency from first fill to last drop. Salts are well suited to low-power coils, which means the draw stays consistent as the tank empties, as long as the wick is still saturated. If flavour thins or the draw becomes airy when the pod is near empty, refill before the cotton dries out. Vaping on a nearly dry coil is the fastest way to a burnt taste and a ruined coil.

Realistic expectations. This is not a liquid for cloud chasing, and it is not suited to a high-power sub-ohm tank. Used in a pod kit at low power, it gives a satisfying, flavour-rich vape that is easy to carry, easy to refill and easy to keep going through a working day.

Bottle, packaging and build quality

The bottle is a standard 10ml plastic dropper-style bottle with a narrow nozzle, built for filling small pod and tank openings without spilling. The cap is child-resistant and tamper-evident, as UK rules require for nicotine-containing liquids, and the label carries the legally required health warning, ingredient list and strength information. You will also find batch details and a best-before date on the label or packaging, which is worth checking when you buy.

What the packaging gives you:

• Narrow nozzle. A slim tip fits most pod fill ports and tank fill holes. Hold the bottle upright over the port and squeeze gently to avoid flooding the device.
• Child-resistant cap. It is deliberately slightly awkward to open. Always refit it fully after use and keep the bottle out of reach of children and pets.
• Tamper-evident seal. If the seal is already broken when you receive the bottle, do not use it and contact us so we can sort it out.
• Health warning. Nicotine is addictive, and the label says so. Read it before you use the product.

Storage. Keep the bottle upright, tightly closed, away from direct sunlight and away from heat. Light and warmth degrade nicotine over time and can darken the liquid. A drawer or cupboard at room temperature is ideal. If you carry a bottle with you, put it in a small sealable bag so a leak in a bag or pocket does not spoil the rest of your things. Avoid leaving it in a car, where temperatures rise quickly in summer.

Shelf life. Unopened and stored properly, nic salt liquids generally keep their flavour and strength for a year or more. Once opened, aim to finish the bottle within a few months. A change in colour is normal, since nicotine oxidises and the liquid can darken gradually, but a very different smell or a harsh taste is a sign to replace it.

Spills and safety. Nicotine liquid is harmful if swallowed and can be absorbed through skin. If you get liquid on your hands, wash with soap and water. If a child or pet swallows any, seek medical help immediately. Wipe up spills with kitchen roll and dispose of it with household waste. Treat a 10ml bottle at 20mg/ml with the same care you would give any medicine or cleaning product.

Coils, mesh and compatible devices

Nic salt liquid at 20mg/ml is designed for low-power, restricted-draw hardware. Using it in the wrong kind of device is the most common reason people feel it is too harsh, too weak or too wasteful, so it is worth getting the pairing right.

What works well:

• Refillable pod kits. The natural home for this liquid. Look for devices with a coil resistance between roughly 0.8 and 1.2 ohm, running at about 10 to 20 watts. Many pod systems tell you the ideal wattage on the coil or in the manual.
• Low-wattage MTL tanks. A small tank with a tight airflow and a 0.8 to 1.2 ohm coil works well. Keep the power low and the draw restricted.
• Mesh pod coils. Mesh coils have a larger heating surface and tend to give more even flavour at low power. They are a good match for fruit and iced flavours, and they usually last well with salts, provided you do not run them dry.
• Ceramic and cotton wick coils. Both work. Cotton gives slightly purer flavour, while ceramic copes well with sweeter liquids and tends to resist burning.

What to avoid:

• Sub-ohm tanks (below about 0.5 ohm) at high power. At 20mg/ml and big vapour production, you would take in far more nicotine than is sensible, and the liquid would disappear very quickly.
• Devices needing a thin low-VG liquid you have not checked. If a device is built only for very high-VG juice, it may flood with a thinner salt liquid. Check what the manufacturer recommends.
• Old, flooded or leaking tanks. If a device already leaks, fix that first, since nic salt is expensive to waste.

Matching coil to power. A coil at 1.0 ohm commonly works comfortably around 12 to 18 watts, while a 0.6 ohm mesh coil often prefers about 15 to 22 watts. Start at the low end of the recommended range, and nudge it up only if the vapour feels too cool or thin. If the liquid tastes burnt, drop the power and check the coil.

Coil life. A coil used with a sweet salt liquid typically lasts one to three weeks depending on how often you vape. When flavour dulls, the draw feels dry or you taste burnt cotton, replace the coil. A new coil should be primed with a few drops of liquid directly on the cotton, then left for several minutes before you press the button. This avoids dry hits and extends coil life.

Fill limits. UK rules limit refillable tanks and pods to 2ml, so most pod kits and tanks compatible with this liquid will hold exactly that or less. A full 10ml bottle will refill several of them, which is part of why salts suit people who top up through the day.

Battery and charging for the device you pair it with

The liquid does not have a battery, so the question is about the device you choose. Because nic salts work well at low power, the hardware they suit tends to be compact, with batteries that fit in a pocket and charge quickly. Understanding how to look after the battery in your kit helps both safety and day-to-day reliability.

Typical battery sizes for compatible kits. Pod kits suited to nic salts usually have built-in batteries between about 400mAh and 1,000mAh. A 400 to 650mAh battery commonly lasts a light to moderate user most of a day when running at 10 to 15 watts. A 800 to 1,000mAh battery gives a comfortable margin for heavy users or higher-wattage coils. Remember that mAh is a measure of capacity, and real-world runtime also depends on the coil resistance and the power setting you run.

• Charging port. Most current kits use USB-C. It is reversible, widely available and charges quickly. Some older kits use micro-USB.
• Charging time. Expect about 30 minutes to 90 minutes to refill a small pod battery from empty, depending on the battery size and the charger.
• Pass-through. Some devices allow vaping while charging, but it is not ideal. If the kit does not specify pass-through support, let it charge first.

Good charging habits:

• Use a sensible charger. A standard phone charger or a computer USB port is fine. Do not use a mismatched high-output fast charger unless the manufacturer says the device supports it.
• Do not leave it unattended overnight on a soft surface. Charge on a hard, non-flammable surface such as a desk or a tile, and unplug when full.
• Avoid extremes of temperature. Do not charge or leave the device in a hot car, in direct sunlight or in freezing conditions.
• Stop if it misbehaves. If a battery swells, gets unusually hot, smells strongly or does not hold a charge, stop using it and dispose of it safely.

Battery recycling. Never put vape batteries or devices in your ordinary bin or household recycling. Lithium batteries cause fires in waste lorries and sorting plants. Take old devices, loose batteries and charging cables to a household waste recycling centre, or use the in-store drop-off points that many retailers and supermarkets provide for small electricals and batteries. Empty plastic bottles can usually be rinsed and recycled according to your local council’s guidance.

Keeping a spare. If your daily routine depends on your vape, consider a second charged device or a small power bank so a flat battery does not leave you without a way to manage cravings at a bad moment.

Who Nasty Liq 20mg is for, and who should skip it

A product at the top of the legal nicotine range is not right for everyone, and being straight about that is part of buying responsibly. Here is a realistic picture of who this liquid suits.

It may suit you if:

• You are an adult smoker who wants to switch to vaping and you currently smoke around 10 or more cigarettes a day.
• You already use a refillable pod kit and want a flavoured 10ml refill in the strength that stops cravings reliably.
• You like a low-vapour, discreet vape with a firm but smooth nicotine hit.
• You prefer bottled liquid to sealed prefilled pods because you can choose the flavour and refill as often as you like.
• You are replacing a disposable habit and want a similar flavour-first experience in a refillable format.

It is probably not right if:

• You have never smoked or used nicotine. Do not start with a strong salt. Vaping is intended to help existing smokers, not to introduce new users to nicotine.
• You are under 18. We cannot sell to you, and it is illegal in the UK to sell nicotine vapes and e-liquid to anyone under 18.
• You are pregnant or breastfeeding. Nicotine is not recommended in pregnancy. Ask your GP, midwife or local stop smoking service for advice on the safest route.
• You have a heart condition or high blood pressure. Talk to your doctor before using any nicotine product.
• You are a light smoker. A strength of 20mg may be more than you need. A 10mg salt will probably be more comfortable.
• You want big clouds. This is a low-power salt liquid, not a sub-ohm juice.

Stopping smoking support. If your aim is to quit nicotine altogether, vaping can be part of a plan to cut down gradually, but it tends to work better alongside support. The NHS Better Health service and local stop smoking services offer free help, and they can advise on strengths and tapering. Many people step down from 20mg to 10mg and then 5mg over a number of weeks.

Using it responsibly. Keep it away from children and pets, do not share it with anyone who is not an adult smoker, and treat the nicotine content seriously. Our site does not offer medical advice, and nothing here replaces a conversation with a health professional about your own circumstances.

How to fill, use and troubleshoot your Nasty Liq

Using nic salt liquid is simple, but a few habits make a big difference to flavour, coil life and comfort. This section walks through first use, daily use and the problems people run into most often.

Filling a pod or tank:

• Turn the device off if it has a button lock, and remove the pod or open the tank.
• Locate the fill port, which is usually a small rubber bung or sliding cover on the side or top.
• Hold the bottle upright over the port and squeeze slowly. Fill to just below the maximum line and avoid covering the central air tube.
• Close the port, refit the pod and wait at least five minutes before the first draw so the cotton can saturate.
• Take two or three gentle draws without pressing the button, if your device allows it, to pull liquid into the coil.

Daily use. Take slow, steady draws of two to four seconds. A restricted draw feels closer to smoking and gives cleaner, more defined flavour. Because salts deliver nicotine quickly, resist the temptation to chain vape. Pause between sessions and notice how you feel.

Troubleshooting the usual problems:

• Burnt or harsh taste. Usually a dry or worn coil. Refill the pod, wait, and prime again. If it persists, replace the coil. Avoid vaping when the tank is nearly empty.
• Gurgling or spitting. Condensation or excess liquid in the airflow. Tip the pod and blow gently through the mouthpiece, wipe it dry and refill slightly lower.
• Leaking. Check that the pod is seated, the fill port is closed and the pod is not overfilled. Cold weather or flying can also cause leaks. Store the device upright.
• Weak flavour. The coil may be tired, the battery low, or you may be vaping a very similar flavour for too long. Replace the coil or switch flavour for a few days.
• Too harsh in the throat. Lower the power, take shorter draws, or move to a lower strength. A 20mg salt is firm even when smooth.
• Lightheaded or nauseous. Stop, sip water, and rest. Next time take fewer draws or choose a lower strength.
• Device does not fire. Check the battery, clean the contacts with a dry cotton bud and make sure the pod is properly seated.

Cleaning. Wipe the mouthpiece and pod contacts with a dry tissue every few days. If the device is flooded, remove the pod, let it dry and use a fresh coil. If a problem persists after you have tried these steps, it is worth checking the manufacturer’s guidance for your specific device.

Value for money and honest comparisons

Value in e-liquid is a mix of price per millilitre, how long a bottle lasts and whether you enjoy the flavour enough to finish it. The 10ml size is the legal limit for nicotine-containing bottles, so you cannot buy a larger nic salt bottle in the UK. Prices are listed on the page and can change, so check the current figure there. What is worth knowing is how this product sits against other routes.

Against disposables. Disposable vapes have been banned from sale in Great Britain since June 2025, so the comparison is mostly historical for people who used them. A refillable pod kit with a bottle of nic salts costs a little more up front for the device, but each refill is cheaper than buying a new disposable, there is far less waste, and you can switch flavour whenever you like. Over a few weeks, refilling is cheaper and considerably better for the environment.

Against other nic salt brands. Several brands compete in the 10ml 20mg space, and a fair comparison looks like this:

• Elfliq and similar disposable-brand salts. These bring familiar candy and ice flavours in a 10ml bottle, and Nasty Liq sits in the same part of the market with a comparable flavour-first approach.
• IVG Salts and Hayati-style ranges. These offer a wide flavour catalogue and are a sensible alternative if you want more variety or a different house style. Prices are broadly in the same band.
• Dinner Lady and other premium salts. Often more complex and dessert-focused, usually at a higher price per bottle. If you want elaborate recipes they can be worth it, but they cost more than a straightforward fruit or ice salt.
• Pod Salt and similar pod-focused brands. These are well known for pairing with pod kits and have a loyal following. They tend to be priced a little higher than budget-leaning lines.

None of these is automatically better, and flavour preference is personal. The honest summary is that Nasty Liq is a competitively placed, flavour-led salt line, and the choice between it and its neighbours will come down to which specific flavour you like and the price on the day.

Getting more for your money. A few habits stretch a bottle: use the lowest power that gives you good flavour, replace coils at the first sign of dullness rather than running them until they burn, avoid chain vaping, store the bottle properly, and buy a flavour you know you enjoy before committing to several bottles. If you find you use a bottle quickly, buying two at once can reduce the cost of delivery per bottle.

UK rules, recycling, delivery and returns

Buying e-liquid in the UK comes with a framework of rules that shape what you see on the shelf and how you use it. Knowing the basics helps you read labels and shop with confidence.

• Age. Nicotine vapes and e-liquids can only be sold to people aged 18 or over. Our checkout is age-verified, and we do not sell to anyone under 18.
• Nicotine strength. UK rules cap e-liquid strength at 20mg/ml, which is the strength of this product. The same cap applied to disposables and prefilled pods before disposables were withdrawn from sale.
• Bottle size. Bottles containing nicotine are limited to 10ml, and refillable tanks and sealed pods to 2ml. That is why this product is sold in 10ml.
• Packaging. Nicotine products must carry health warnings and use child-resistant, tamper-evident packaging.
• Disposables. Single-use vapes have been banned from sale across Great Britain since June 2025. A refillable kit with a bottle of nic salts is not covered by that ban.

Recycling. Rinse empty plastic bottles and check your local council’s guidance on whether bottles with residual flavour can go in kerbside recycling; caps and nozzles are sometimes accepted and sometimes not. Batteries, devices and charging leads should go to a household waste recycling centre or a retailer or supermarket drop-off point, and never in ordinary bins. Used coils and pods can usually be treated as small electrical waste if they contain metal and wiring, so check your local centre.

Delivery. We dispatch to UK addresses. Orders are packed discreetly, and a signature or an adult may be needed at delivery because the contents are age-restricted. Delivery times and costs are shown at checkout, and tracking is provided once the order is dispatched. We do not deliver nicotine products outside the UK.

Returns and faults. Because e-liquid is a consumable and nicotine products cannot be resold once opened, we cannot accept returns of opened bottles for change of mind. If your bottle arrives damaged, leaking, with a broken tamper seal, or you receive the wrong flavour, contact us promptly with your order number and a photo, and we will arrange a replacement or refund. Your statutory rights are not affected by anything on this page.

Responsible use. Nicotine is addictive. This product is for adult smokers and existing nicotine users only. Keep it out of reach of children and pets, follow the guidance on the label, and if you want help to stop smoking or stop vaping, your local stop smoking service and the NHS can support you free of charge.
