Slush Brew by Ohm Brew 10ml Blue Mix 3mg: overview

Slush Brew by Ohm Brew 10ml Blue Mix 3mg is a ready-to-vape nicotine e-liquid in the standard UK 10ml bottle, sold at 3mg/ml (0.3%) nicotine strength. It belongs to the Slush Brew line from Ohm Brew, a brand whose catalogue leans towards fruit, candy and soft-drink style flavours, and the Blue Mix variant sits in the blue-fruit slush family: a sweet, cold, slightly tangy profile that imitates a frozen fruit drink rather than a plain fruit juice. If you have tried blue raspberry, blueberry-and-raspberry or blue slush style liquids before, you already have a decent map of the territory.

A 3mg liquid is, in practice, a freebase-style product rather than a nicotine salt, because nicotine salts are normally sold at 10mg/ml and 20mg/ml. That matters for how you use it. Low-strength freebase liquid is designed for people who vape in volume on a refillable tank, usually with a sub-ohm or high-airflow coil, and who want nicotine present but gentle. It is a different job from a nic salt in a small pod kit, where the nicotine is stronger and the puffs are smaller.

One 10ml bottle at 3mg/ml contains 30mg of nicotine in total (10ml multiplied by 3mg/ml). That figure is worth keeping in mind because it puts the strength in context. A 10ml nicotine salt bottle at 20mg/ml holds 200mg, which is almost seven times as much nicotine in the same volume. Neither number is better in the abstract; they suit different devices and different habits.

This page is a plain-English guide to what the bottle is, how it behaves in a tank, which devices suit it, how to decide whether 3mg is the right strength, how to fix common problems and how it compares with other options we stock. We describe Blue Mix by its flavour family and by the figures printed on the bottle. We do not have Ohm Brew's recipe, so we do not pretend to give a note-by-note breakdown, and where a detail varies by batch, such as the exact VG/PG ratio, we tell you to check the label rather than guess.

One firm point before we go further. This product contains nicotine, which is addictive. It is for adults aged 18 or over who already smoke or vape. It is not for under-18s, non-smokers, or anyone pregnant or breastfeeding, and it should be kept out of reach of children and pets.

Flavour profile: what Blue Mix tastes like

In vape naming, blue almost always signals a blue raspberry and/or blueberry character, and mix suggests more than one fruit element in the recipe. Slush Brew adds the second half of the picture: the liquid is built to taste like a crushed-ice fruit drink, which means sweetness up front, a clear fruity centre and a cold finish. That is the family Blue Mix belongs to. The precise balance between raspberry, berry and any other fruit is Ohm Brew's own, so treat the descriptions below as what to expect from the style rather than a guaranteed tasting note.

A typical blue slush liquid unfolds in three stages:

• On the inhale: a bright, sweet berry impression, often with a slight sharpness that stops the flavour tasting flat. Blue raspberry is tangy rather than juicy, so expect more candy-like zing than ripe-fruit depth.
• Through the middle: the fruit rounds out and the cooling effect arrives. Many slush and ice liquids use a synthetic cooling agent. The result is a cold sensation on the tongue and throat rather than a minty taste.
• On the exhale and aftertaste: a clean, sweet finish with a lingering chill. Sweet liquids can leave a faint sugary coating on the palate after a long session, which is normal.

Why does the strength matter for flavour? Nicotine has its own slightly peppery bite. At 3mg/ml there is very little of it, so the fruit and the cooling effect are not competing with a strong throat hit. Low-nicotine liquids therefore tend to taste smoother and sweeter than the same recipe at 12mg or 18mg, and the flavour is easier to pick out. That is one reason people who vape large clouds on a sub-ohm tank prefer a low strength: they get taste without a scratchy throat.

Temperature changes how the flavour reads. Run the coil on the lower side of its wattage range and the fruit comes through cooler and cleaner. Push the power up and the sweetness intensifies, the cooling effect softens and the vapour feels warmer. If Blue Mix tastes too sweet or slightly synthetic, drop the wattage by a few watts before deciding it is not for you. If it tastes muted, open the airflow less or raise the power slightly.

If you want a close comparison within our range, the nic salt blue slush liquids from Crystal Clear and Double Brew sit in the same flavour family at stronger nicotine levels, and the Ohm Brew Badass Blend 50ml shortfills offer other blue and berry flavours in a larger bottle. Because those use different recipes and strengths, think of them as cousins rather than substitutes.

One practical note on sweet liquids: heavily sweetened e-liquids deposit more residue on the coil over time, which is why flavour can fade after a week or so and a fresh coil makes the same bottle taste new again. We cover that in the coil and troubleshooting sections.

Specifications and bottle design

Here are the facts worth knowing before you buy, drawn from the product name, the 10ml format and the rules that apply to nicotine e-liquid in the UK.

• Product: Slush Brew by Ohm Brew, Blue Mix flavour
• Type: ready-to-vape nicotine e-liquid, no mixing required
• Bottle size: 10ml, the largest size permitted for nicotine-containing e-liquid in the UK
• Nicotine strength: 3mg/ml (0.3%)
• Total nicotine per bottle: 30mg
• Nicotine type: freebase-style at this strength, not a nic salt
• VG/PG ratio: printed on the bottle label; check it, because it affects which coils and devices suit the liquid
• Intended use: refillable tanks and refillable pod devices that accept loose e-liquid

The bottle is the usual UK format: a small squeezable plastic bottle with a narrow nozzle, a child-resistant cap and a tamper-evident ring that breaks the first time you open it. Those features are required for nicotine e-liquid sold in Great Britain, so they are not a design flourish, but they do shape how the bottle feels to use. The narrow nozzle is meant to fit into the fill port of most tanks and pods, and a gentle squeeze controls the flow. Squeeze slowly. A hard squeeze on a thick liquid pushes out more than you intended and floods the fill port.

The label carries the information the rules require: ingredients, the nicotine content, a batch or lot number, the manufacturer's details and a written health warning that the product contains nicotine, which is a highly addictive substance. Keep the box or take a photo of the batch code if you want to track a particular bottle, since that is the reference a retailer or manufacturer will ask for if there is ever a problem.

There is also a practical limit that comes with the 10ml format. UK rules cap refillable tank capacity at 2ml for nicotine vaping devices. That is why a 10ml bottle gets you through multiple tank fills rather than being poured in all at once, and why you will be refilling more often on a small-capacity tank than you may be used to from other countries.

Storage and shelf life are straightforward. Keep the bottle upright, capped, out of direct sunlight and away from heat. Most e-liquid carries a best-before date on the label, commonly 12 to 24 months from manufacture. Heat and light degrade flavour and darken the liquid, so a bottle left on a car dashboard will taste noticeably worse than one kept in a drawer.

Performance and vapour delivery

E-liquid does not have a puff count the way a pod or disposable does, because the number of puffs depends on your device, your power setting and how you vape. What we can do is give you honest planning numbers.

On a sub-ohm tank run at around 40 to 70 watts, a typical four-second pull uses somewhere in the range of 0.05 to 0.1ml of liquid. On that basis, a 10ml bottle gives you roughly 100 to 200 pulls at the heavy end and more if you vape at lower power or take shorter draws. These are estimates, not lab results, and your own consumption will vary with coil resistance, airflow and puff length. On a low-power refillable pod, where each pull is far smaller, the same bottle stretches into the high hundreds or beyond a thousand puffs. A reasonable rule of thumb is to log your first bottle: note the day you open it and the day it runs out, and use that to predict future orders.

Vapour production depends mainly on the VG share of the liquid and on the coil and power you pair it with. Higher-VG blends produce thicker, denser clouds and a softer throat hit. Higher-PG blends carry flavour more sharply and give a firmer throat hit. Because the exact ratio is printed on the bottle, check it and match the liquid to the device. A very thick, high-VG liquid can struggle in a tiny low-power coil with small wicking holes, while a thin liquid can leak from a large, open sub-ohm tank.

At 3mg/ml the throat hit is light. Light does not mean absent: a cold slush liquid has a chilly sensation that some people read as throat hit, but it is not the same as the peppery catch of nicotine. If you used to smoke and are used to a strong throat hit, you may find 3mg too gentle in a restrictive device, and it is better suited to open, airy inhales where you take in a bigger volume of vapour.

What does 3mg actually deliver? The amount of nicotine you absorb depends on how much liquid you vaporise, not just on the strength printed on the bottle. Someone taking 100 big pulls a day on a sub-ohm tank can easily use 5ml of liquid, which at 3mg/ml is 15mg of nicotine passing through the coil. Someone taking 100 small pulls on a pod device may use 1ml of a 20mg/ml salt, which is the same 20mg through the coil. The two experiences can feel similar in total nicotine even though the bottle strengths are very different. This is why the device you use should decide the strength you buy, not the other way round.

In everyday terms, expect smooth, flavour-forward vapour at a gentle nicotine level, with the cold finish being the most noticeable feature. If you want a bigger hit, move to a higher strength rather than raising the wattage to compensate, because turning the power up to chase nicotine mostly burns through liquid and coils faster.

Device pairing, battery and charging

E-liquid does not charge, but the device you put it in does, and battery capacity decides how long a bottle of Blue Mix lasts between charges. Here is how to think about it.

Battery capacity is quoted in milliamp hours (mAh). A rough way to turn that into runtime is to multiply the capacity by the nominal voltage of 3.7V to get watt hours, then divide by your power setting. A 3,000mAh internal battery holds about 11 watt hours. At 60 watts, that is roughly 11 minutes of continuous firing, which works out to around 140 to 160 four-second pulls before you account for losses. In real use, expect less than the theoretical figure, since batteries lose efficiency at high drain and you rarely run at a single steady wattage. The point of the arithmetic is the relationship: more watts, fewer pulls per charge, and more liquid used per pull.

The device types that suit a 3mg freebase liquid fall into three groups:

• Sub-ohm kits and mods: the natural home for a 3mg liquid. Look for a kit with a 0.15 to 0.4 ohm mesh coil and a 2ml tank, driven by an integrated battery in the 1,500 to 3,000mAh range or by a replaceable 18650 or 21700 cell.
• Refillable pod systems with mid-resistance coils: many accept loose e-liquid in 0.4 to 0.8 ohm coils at 15 to 30 watts. Check that the pod is rated for freebase liquid. At 3mg you will get a mild result, so these suit people who want a very light nicotine level.
• Low-power MTL (mouth-to-lung) tanks: these work best with stronger nicotine. 3mg is usually too weak to feel satisfying in a restrictive-draw device, so we would steer you to a higher freebase strength or a nic salt instead.

Charging habits matter more than most people think. Use the cable and charger that came with the device, or a reputable replacement with a suitable output. Charge on a hard, non-flammable surface rather than on a bed or sofa, do not leave a charging device unattended for long periods, and stop using any cell with a torn wrap, dents, swelling or heat while charging. If your device uses removable 18650 or 21700 cells, charge them in an external charger designed for that purpose, carry spares in a plastic case rather than loose in a pocket with coins or keys, and never mix cells of different brands or ages in a multi-cell device.

Most current devices charge over USB-C, with a full charge taking from one to three hours depending on capacity and charger output. A device that stops firing mid-session is telling you the battery has dropped below the cutoff voltage; recharge rather than forcing the button repeatedly, since a flat battery gives weak, lukewarm vapour and a poor impression of the liquid.

Coil and mesh technology

The coil is where the liquid becomes vapour, and the right coil makes a bigger difference to Blue Mix than any other part of the setup. Most modern tanks use either mesh coils or round-wire coils, and both are widely available in resistances from about 0.15 ohms up to 1.0 ohm.

• Mesh coils use a flat or curved sheet of fine metal mesh instead of a wire spiral. The mesh gives a large heating surface, which spreads heat evenly, brings flavour out more consistently and produces dense vapour at moderate power. For a cold fruit liquid, an even heat helps keep the cooling effect clean and the sweetness balanced.
• Round-wire coils are the older design. They respond quickly and can produce crisp flavour, but they heat less evenly, which can mean slightly more variation from pull to pull and a bit more chance of hot spots with thick, sweet liquids.

Resistance, measured in ohms, sets the wattage range. As a guide, a 0.15 to 0.3 ohm sub-ohm mesh coil usually runs at 50 to 80 watts and suits an open, lung-style inhale. A 0.4 to 0.6 ohm coil often runs best at 25 to 40 watts and works well with moderate nicotine strengths. A 0.8 to 1.0 ohm coil sits at the low-power end and is mostly paired with stronger nicotine. Your coil packaging prints a recommended wattage range. Start at the lower third of that range with a new liquid and work upwards in small steps.

The wicking material is usually organic cotton, with some coils using a ceramic wick instead. Cotton wicks respond well to everyday freebase liquids, but they need priming, meaning you must let the new coil soak up liquid fully before firing. Skipping that step is the usual cause of a burnt first-pull taste and a coil that dies after one tank.

How long a coil lasts depends heavily on what you put through it. A sweet, heavily flavoured slush liquid such as Blue Mix tends to leave sugar-like residue on the coil, so expect a lifespan nearer to one week of regular use than three. Signs that a coil is done are a flat or slightly burnt taste, spitting or crackling, and a darker liquid in the tank. Replace the coil rather than turning the power up to compensate, since a tired coil with higher power only tastes worse and gets worse faster.

Swapping between flavours also affects coil life. A coil that has been soaked in one flavour will carry a ghost of it into the next, so pairing Blue Mix with a dedicated tank or a fresh coil keeps the cold, fruity profile clean. If you often switch flavours, a cheap spare tank is a sensible purchase.

Nicotine strength: is 3mg right for you?

Choosing a nicotine strength is the single most important decision you make with any e-liquid, and the right answer depends on your device and your habit rather than on a simple scale. Here is how 3mg/ml fits into the range sold in the UK.

• 0mg: no nicotine, for people who vape purely for the flavour or the habit
• 3mg: low strength, the usual starting point for sub-ohm vaping with large inhales
• 6mg: low to medium, popular with sub-ohm users who want a firmer hit and with moderate-power tanks
• 12mg: medium, for mid-power or MTL devices
• 18mg: high freebase strength, normally used in low-power MTL devices and mostly replaced by nic salts
• 10mg and 20mg nic salts: smooth, stronger nicotine for low-power pod devices; 20mg/ml is the UK legal maximum

Where does 3mg make sense? If you vape a sub-ohm tank at 40 watts or more and take big, airy inhales, 3mg is a sensible, widely used strength. The large volume of vapour means plenty of nicotine reaches you even at a modest strength, and a higher strength in that device tends to feel harsh and gets used up quickly. If you vape a small pod at low power, 3mg will probably feel too weak, because each puff carries a small amount of vapour and very little nicotine.

How do you know if you picked wrongly? A few signs help. If you find yourself chain-vaping, taking far more puffs than usual, getting restless between sessions or reaching for the device within minutes, the strength is probably too low for your habit. If you get a harsh throat hit, a racing feeling, lightheadedness or nausea, it is too high or you are vaping too fast. Adjust one step at a time and give each change a few days before judging it.

If you are a current smoker, do not assume 3mg will replace cigarettes. Many people who switch fully from smoking need more nicotine at the start, either through a higher freebase strength in a low-power device or through a 10mg or 20mg nic salt. A local stop-smoking service can give free, tailored advice and support.

You cannot add a nicotine shot to this bottle. A 10ml bottle is full to the neck, and altering a ready-made nicotine e-liquid by mixing in additives or other liquids is not something we recommend. If you want a different strength, choose a bottle at that strength. Nicotine e-liquid in the UK is capped at 20mg/ml, so there is no stronger product to move up to beyond the nic salt range.

Who Blue Mix is for, and who should skip it

No liquid suits everybody. Here is a frank breakdown of who tends to get on well with Slush Brew Blue Mix at 3mg, and who is likely to be disappointed.

Blue Mix 3mg is a good match for:

• Adult vapers running a sub-ohm tank or mod who want a low, gentle nicotine level
• Vapers who have stepped down from higher strengths and want to keep going lower
• People who like cold, sweet, fruit-forward flavours rather than tobacco, dessert or menthol profiles
• Anyone who wants a ready-made nicotine bottle without mixing shortfills and shots
• People who prefer the large, soft inhale of an airy tank over a tight, restrictive draw

You should probably skip it if:

• You are a heavy smoker or recently stopped smoking, and need a firmer hit in a low-power pod. A nic salt at 10mg or 20mg, or a higher freebase strength, is a better fit
• You use a restrictive MTL pod kit designed for salts, since 3mg freebase will feel thin and may not wick well through its narrow coil
• You dislike very sweet or very cold flavours. Slush liquids are built around both
• You want a tobacco, custard, nutty or other non-fruit profile
• You are under 18, do not smoke or vape, or are pregnant or breastfeeding

It is also worth being clear about expectations. A 3mg liquid is deliberately light. It is not meant to be a one-size-fits-all strength, and the people who enjoy it most tend to be those who vape often, in large draws, and who look for taste and vapour more than nicotine kick.

If you are new to vaping and not sure where to start, the safest approach is to ask a staff member at a local specialist vape shop, or to talk to a stop-smoking adviser, before you decide on a strength. Starting too low is a common reason people drift back to cigarettes, because they find vaping unsatisfying. Starting too high is a common reason for unpleasant first experiences. A short conversation saves both mistakes.

Finally, think about whether you will use the whole bottle. A flavour that suits you in a sample pull can become tiresome by the sixth tank, particularly with very sweet liquids. If you are unsure, consider whether a smaller test run with a couple of different flavours is more sensible than committing to multiple bottles of one.

How to use: filling, priming and your first tank

Getting the setup right the first time avoids almost every complaint people have about a new liquid. Follow these steps with a new tank or a fresh coil.

• Step 1, check the basics. Wash your hands, make sure the tank is clean and dry, and confirm the coil is the right resistance for your device. Check the bottle label for the VG/PG ratio and the batch number.
• Step 2, open the bottle. Twist the child-resistant cap as the label instructs. The tamper-evident ring will break on first opening, which is normal.
• Step 3, open the fill port. Depending on your tank this is a sliding cover, a flip-up cap or a threaded top. Check the manufacturer's guide if you are unsure. Never pour liquid into the central airflow tube.
• Step 4, fill slowly. Tilt the tank, place the bottle nozzle against the side of the fill port and squeeze gently so the liquid runs down the inside wall. Stop below the maximum fill line. Overfilling forces liquid into the airflow path and causes leaks.
• Step 5, prime the coil. Let the filled tank stand upright for 5 to 10 minutes so the cotton soaks through. For a brand new coil, put a few drops directly onto the cotton through the coil's wicking holes before fitting it.
• Step 6, set your power. Begin at the bottom of the coil's recommended wattage range. Take two or three gentle, short pulls without inhaling deeply to confirm vapour is forming and no burnt taste is present.
• Step 7, settle in. Raise the wattage a watt or two at a time until the flavour and temperature suit you. Open the airflow if it feels hot or tight, close it a touch if flavour seems thin.

When refilling mid-session, wait until the liquid is just above the coil wicking holes rather than letting the tank run dry. Letting the coil run on empty is the most common cause of dry hits and shortened coil life. Top up before the tank is nearly empty, wipe the nozzle clean and re-prime for a minute or two.

When you are finished, switch the device off or lock it, cap the bottle firmly and store it upright. If you are carrying a tank in a bag, either empty it or ensure the airflow is shut and the device is locked, since pressure changes in transit can force liquid out.

If you want to change flavour in the same tank, empty it, rinse the parts with warm water, dry them fully, fit a new coil and refill. Re-using a coil that carries the taste of a previous flavour is a common reason people think a liquid tastes wrong.

Finally, vape at your own pace. Take slow, steady draws of three to five seconds on a sub-ohm tank, and pause between pulls so the coil can re-wick. Long, rapid-fire sessions drain the wick faster than it can refill, which is how burnt tastes happen in an otherwise healthy setup.

Troubleshooting common problems

Most problems with a new bottle are about the setup rather than the liquid. These are the issues we see most often and how to deal with them.

• Burnt or dry taste. Usually a coil that has not been primed, a tank that ran low, or power set too high. Refill, re-prime for several minutes and drop the wattage. If the burnt taste persists after a fresh coil, the coil is probably not the issue and the power setting needs another look.
• Weak or muted flavour. Often coil gunk, especially with sweet liquids. Fit a new coil. If it still tastes flat, you may be experiencing vaper's tongue, a temporary loss of taste sensitivity. Switching to a different flavour for a day or two, drinking water and cleaning your tank can help.
• Leaking from the tank. Check the tank is assembled correctly, the seals are seated, the fill port is closed fully and the liquid is below the fill line. A very thin liquid in a large-wicking-hole coil, or a coil that is loose in its seat, can cause leaks. Altitude and temperature changes in transit also push liquid out.
• Gurgling or spitting. Excess liquid in the airflow path or a condensation build-up. Blow gently through the mouthpiece with the device off to clear it, and wipe the drip tip.
• Harsh throat hit. More common on strong liquids but possible at 3mg if the power is too high or the coil is burnt. Lower the wattage, open the airflow and check the coil.
• Not enough nicotine. If 3mg feels too light for your device, step up to a higher strength in a separate bottle rather than trying to compensate with extra power.
• Liquid does not come out of the bottle. The nozzle may be partly blocked or a vacuum has formed. Squeeze gently, release and try again, or remove the nozzle with the cap on the other end of the bottle according to your design.
• Sticky or dark coil. A sign of caramelised sweetener. Replace the coil. Running a clean coil is the simplest fix.
• Device will not fire or fires weakly. Check the battery charge, the connection between tank and battery and whether the coil has failed. Remove dirt from the contact pins with a dry cloth.

If you have tried the obvious fixes and a particular bottle still seems wrong, such as a strange chemical smell, unusual colour or a taste that is clearly different from what you expected, stop using it. Keep the bottle and the batch number, and contact the retailer. Do not keep vaping a liquid that tastes or smells off.

Any skin contact with nicotine liquid should be washed off promptly with soap and water. If liquid gets in the eyes, rinse with clean water and seek medical advice. If swallowed, or if a child or pet has been exposed, contact emergency services or NHS 111 straight away.

Value for money and how it compares

Value is more than the price on the page. It comes down to cost per millilitre, how long a bottle lasts in your device, how often you replace coils and whether the strength actually suits you. Here is how to work it out and how Blue Mix 3mg compares fairly with the other options we stock.

Start with cost per ml. Divide the price by ten for a 10ml bottle. As a purely illustrative example, not our price, a bottle at £4.00 works out at 40p per ml. A 50ml shortfill with a nicotine shot added might cost less per ml, but you also have to buy the shot, mix it, shake it and let it rest. The 10ml format trades a slightly higher cost per ml for convenience: no mixing, a small bottle that is easy to carry and no leftover half-bottle going stale.

On a sub-ohm tank, liquid consumption is high, so the bottle price matters. If you use five millilitres a day, a 10ml bottle lasts two days, which may push you towards a larger format if cost matters most. If you use one or two millilitres a day, a 10ml bottle lasts around a week and the convenience is worth the small premium.

Here is an honest comparison with the main alternatives:

• Ohm Brew Badass Blend 50ml shortfills: a lower cost per ml and a bigger bottle, ideal if you vape daily on a sub-ohm tank. The trade-off is that you must add a nicotine shot to reach 3mg, and the large bottle is less portable.
• Double Brew nic salts, 10ml at 20mg: a stronger, smoother hit in a small pod device. These cost about the same per bottle but deliver far more nicotine per ml and are used in a different type of device. They are not interchangeable with a 3mg freebase.
• Crystal Clear nic salts, Blue Slush: another blue slush option in the nic salt format. Good for pod kits, wrong for sub-ohm tanks.
• Pre-filled pods and kits: convenient and tidy, but the pod is often discarded after use, which raises the running cost and the waste. Refilling a tank from a 10ml bottle usually costs less per day once you own the hardware.
• Single-use disposables: the sale of these has been banned in Great Britain since June 2025, which is part of why more adults have moved to refillable tanks and pods. A refillable setup with a 10ml bottle gives you more control over strength and flavour, with less waste than a throwaway product.

Remember the hidden costs of a refillable setup too. Coils cost a few pounds each and last one to two weeks. Over a month, add the coil cost to your liquid cost before you compare it with any other format. A sweet slush liquid shortens coil life a little, so factor that in.

In short, Blue Mix 3mg offers fair value for people who use a sub-ohm tank, want a ready-mixed low strength and value the convenience of a small, carry-anywhere bottle. If you vape heavily, buying in 50ml shortfill format will usually cost less. If you use a pod kit, a nic salt is likely better value because it is built for that device.

UK rules, storage, safety and recycling

Selling and buying nicotine e-liquid in the UK comes with clear rules, and knowing them helps you shop with confidence and use the product safely.

• Age: you must be 18 or over to buy nicotine vaping products. Expect age verification at checkout and possibly on delivery.
• Strength: nicotine e-liquid is capped at 20mg/ml. That same limit applies to nicotine in pods and any other vaping product sold in the UK, so you will never see legitimate liquid above it.
• Bottle size: nicotine-containing e-liquid bottles are limited to 10ml, which is why this product comes in that size.
• Tank size: refillable tanks and pods are limited to 2ml capacity for nicotine devices.
• Packaging: bottles must be child-resistant and tamper-evident, and must carry the nicotine health warning and ingredient list.

For safe storage, keep Blue Mix in its original bottle with the cap on tight, upright and out of sight and reach of children and pets. Do not decant it into drinks bottles or unlabelled containers. Keep it away from direct sunlight and heat sources. Concentrated nicotine is harmful if swallowed or absorbed through the skin in large quantities, and the sweet fruit smell can be attractive to children, so treat the bottle like any household chemical.

Never use e-liquid in a device not designed for it, and never alter a ready-made nicotine liquid by adding flavourings, additives or other substances. Do not vape while driving in a way that distracts you, and follow the smoking and vaping policies of workplaces, trains, aircraft and venues.

Recycling matters too, and it is simple to do properly.

• Devices, batteries and chargers: never put these in household bins or recycling. Lithium batteries can start fires in collection vehicles and sorting plants. Take old devices to a waste electrical recycling point, a council household waste recycling centre, or a retailer that accepts returned vapes. Shops that sell vaping products are required to provide take-back for waste vapes, and many also accept batteries.
• Coils: they are small metal and cotton parts. Check with your local council about whether used coils can go in household waste or should go to the recycling centre.
• Empty e-liquid bottles: these are plastic, and local rules differ. Many councils accept clean, empty plastic bottles in household recycling, but you should check your local guidance first. Let any residue dry out inside the bottle, remove the cap if your council asks, and never pour liquid down a drain.
• Packaging: cardboard outer boxes and inserts can usually go in household recycling.

Used responsibly, a 10ml refillable setup produces far less waste than a stream of single-use devices, but only if the batteries, coils and bottles end up in the right place. A drop-off point is rarely more than a short trip away.
