What Nasty Juice Slow Blow 50ml Is

Nasty Juice Slow Blow 50ml is a tropical fruit e-liquid from Nasty Juice, a brand with Malaysian roots that built its following on bold, sweet-leaning flavours and loud, graphic bottle artwork. This is the shortfill version: 50ml of nicotine-free liquid supplied in a larger bottle, typically 60ml, so there is empty space left for you to add a nicotine shot if you want a nicotine strength. The flavour is built around kiwi, passion fruit and guava, a combination that reads as juicy and slightly tart rather than creamy or dessert-like.

Shortfills exist in the UK because of the way e-liquid is regulated. Under the Tobacco and Related Products Regulations 2016, liquid that contains nicotine can only be sold in bottles of 10ml or less, at a maximum strength of 20mg/ml, and refillable tanks are limited to 2ml of capacity. Nicotine-free liquid is not subject to the 10ml bottle limit, so a 50ml bottle of 0mg liquid can be sold legally alongside separate 10ml nicotine shots. You then decide whether to add nicotine and how much, rather than buying a fixed strength off the shelf.

Slow Blow is normally a 70VG/30PG blend, meaning 70 per cent vegetable glycerine and 30 per cent propylene glycol. That ratio is designed for sub-ohm tanks and other open-airflow hardware. Thicker liquid produces dense vapour and a soft, rounded inhale, but it needs a coil with generous wicking holes to feed it properly. The hardware sections further down explain what to pair it with.

Quick facts at a glance:

• Brand: Nasty Juice
• Product type: 50ml shortfill e-liquid, supplied at 0mg nicotine
• Flavour direction: kiwi, passion fruit and guava, fruity and lightly tart
• Typical base: 70VG/30PG, so check the label of the batch you receive
• Bottle: 50ml of liquid in a 60ml bottle with room for one 10ml nicotine shot
• Best suited to: sub-ohm tanks and higher-wattage refillable kits
• Age restriction: 18+ only, in line with UK law

This guide is written to be practical rather than promotional. It covers how the liquid tastes, how to mix and vape it, what tends to go wrong, and where it fits next to other 50ml options. Formulations can change between batches, so treat the bottle label as the final word on VG/PG split, bottle size and ingredients.

Flavour Profile: Kiwi, Passion Fruit and Guava

Slow Blow leads with kiwi, and the first thing most people notice on the inhale is a green, slightly sharp fruit note rather than a sugary one. Kiwi has a natural tartness that cuts through the sweetness of the base, so the flavour stays lively instead of turning syrupy. Passion fruit sits underneath, adding a tropical, slightly floral acidity, and guava rounds things out with a softer, perfumed sweetness that lingers on the exhale.

The three fruits do not arrive at the same moment. On a slow draw, the kiwi and passion fruit tend to dominate the front of the inhale, while the guava appears as the vapour settles on the palate and carries through the exhale. On a faster, warmer draw the flavours blend into one general tropical-fruit impression. Neither approach is wrong; it simply depends on how much airflow and power you are using.

It is worth being honest about what this flavour is not. There is no menthol or ice component in the standard Slow Blow, so the vapour is warm to neutral in temperature rather than cooling. There is also no cream, custard or dessert layer, which keeps it closer to a fruit-juice style than a candy or bakery style. If you want a chilled finish, some vapers add a few drops of a menthol additive, or choose an iced variant from the same range where one is available.

Sweetness is moderate to noticeable. The base liquid is VG-heavy, and vegetable glycerine has a mild sweetness of its own, which is why high-VG fruit liquids often taste rounder and sweeter than their 50/50 counterparts. That sweetness builds slightly over a long session, so some vapers find a few tanks in a row enough before they want a break or a change.

A few practical points affect how the flavour comes across:

• Power: lower wattage within your coil's range keeps the fruit crisp and the kiwi sharper, while higher wattage warms the vapour and pushes the guava and passion fruit forward.
• Coil age: a fresh coil shows the full flavour; as a coil gunks up, fruit flavours dull first, and a faintly burnt note can creep in.
• Steeping: leaving a freshly mixed bottle for a day or two lets the nicotine shot and flavour blend, usually giving a more even taste than vaping straight away.
• Nicotine: adding a nicotine shot slightly mutes fruit flavour and adds a little throat warmth, which some find helpful and others find distracting.

Overall, the flavour suits people who like all-day fruit liquids with some bite, and who find purely sweet berry or candy profiles cloying after a while.

Vapour Production and Performance

The headline performance feature of a 70VG/30PG liquid is vapour volume. Vegetable glycerine produces more visible vapour than propylene glycol, so on a suitable sub-ohm tank at 50 to 80 watts Slow Blow produces dense, thick clouds with a smooth, full inhale. Throat hit is low to moderate at 0mg and increases only modestly once a nicotine shot is added, which is part of why this style is popular with people who want volume without harshness.

Because this is a bottle of liquid rather than a device, puff count depends entirely on your hardware and habits. As a rough guide, a typical 5ml tank of sub-ohm vapour might last a heavy user a single day and a lighter user two to three days. A 50ml bottle is therefore around ten refills of a standard 5ml tank, and in practice many vapers get anywhere from one to four weeks from a bottle. The value section later in this guide breaks the numbers down.

Performance in practice depends on a handful of variables:

• Wicking speed: thick liquid moves slowly through cotton. If your coil has small wicking holes, you will get dry hits at higher power. Coils with large ports are designed for 70VG and avoid the problem.
• Airflow: open airflow cools the vapour and increases volume, while a tighter draw concentrates flavour and warmth. Many users settle on a mid-open setting.
• Coil resistance: lower resistance coils (roughly 0.15 to 0.4 ohm) run at higher wattage and use more liquid per puff.
• Liquid temperature: in cold weather, VG-heavy liquid thickens. If your tank starts to dry-hit in winter, let the bottle and tank warm to room temperature first.

Consistency is generally good from the first puff to the last of a tank, provided the coil is primed correctly. The most common performance complaint with any high-VG shortfill is not the liquid itself but a coil that was not left to soak, so a few minutes of patience after refilling is worth it.

It is also worth being clear about what this liquid is not designed to do. It is not intended for small, tight-draw pod kits that use low-wattage mouth-to-lung (MTL) coils. Those devices are built for thinner liquid, often 50/50 or nicotine salt blends, and a 70VG liquid can choke the wick, produce muted flavour and cause leaks. If you use a pod system, check that it explicitly supports high-VG liquid before buying a 50ml bottle.

Finally, think about throat hit and vapour in combination. At 3mg/ml in an open-airflow tank, the experience is soft and voluminous: plenty of vapour, light nicotine feel per puff, and a flavour that stays present through the exhale. If you want a firmer hit, it is better to raise the nicotine strength than to push the wattage, because excess heat shortens coil life and sharpens the fruit into something closer to a burnt-sugar note.

Bottle Design and Build Quality

Nasty Juice has a recognisable visual identity, and the Slow Blow packaging follows that style: bold colours, cartoon-influenced artwork and large type on the front label. The label is there to be noticed on a shelf, but it also carries the information you need, including the flavour name, the 50ml volume, nicotine content, ingredients and batch details. Because label layouts are updated from time to time, the version you receive may differ slightly in artwork from the pictures on this page.

The 50ml of liquid is supplied in a 60ml plastic bottle. That extra 10ml of headspace is deliberate: it is the room you need to add one standard 10ml nicotine shot without pouring any liquid out. The bottle body is soft and squeezable, which makes it easy to push liquid out, and it has a narrow nozzle designed to fit most tank fill ports. If you use a tank with a very small fill hole, such as some top-fill designs, it is worth checking the nozzle width before you buy.

Build quality of the packaging matters more than it might seem, because e-liquid leaks are messy and nicotine is a skin irritant. Reputable shortfill bottles from established brands typically include a tamper-evident seal and a child-resistant cap. When your bottle arrives, check that:

• the outer seal or tamper-evident ring is intact before you open it;
• the cap turns and seals firmly, with no cracks in the plastic;
• the label is complete and legible, with a batch number and best-before date;
• there is no liquid residue around the nozzle or inside the outer packaging.

If anything looks wrong, do not use the bottle and contact customer service with a photo and your order number so it can be reviewed.

The plastic bottle is also a practical advantage over glass for everyday use. It will not shatter if dropped, it is light enough to carry, and the nozzle gives you control when filling a tank. The trade-off is that soft plastic can be squeezed too hard, so fill slowly to avoid overfilling or flooding the airflow. When you are not using it, keep the cap on tight and store the bottle upright.

The cap and nozzle design is simple, and there are no moving parts or electronics to fail. That simplicity is a point in the favour of any e-liquid: build quality comes down to the seal, the plastic and the label, and all three are easy to inspect on arrival. Because the bottle is oversized relative to the liquid inside, it also makes shaking and mixing straightforward, which is exactly what you want after adding a nicotine shot.

Choosing the Right Nicotine Strength

Slow Blow 50ml arrives at 0mg, so the first decision is whether you want nicotine at all. If you do, the standard approach is to add one 10ml nicotine shot to the 60ml bottle, which brings the whole bottle up to a mild strength. Because the 50ml of liquid sits in a 60ml bottle, the maths is simple and predictable.

The strength you end up with depends on the shot you choose:

• 10ml shot at 18mg/ml: gives 3mg/ml across 60ml (10 x 18 / 60).
• 10ml shot at 20mg/ml: gives roughly 3.3mg/ml across 60ml.
• Two shots: would give roughly double, but they will not fit in a 60ml bottle with 50ml already inside. You would need to pour out some liquid or transfer everything into a larger empty bottle first.
• No shot: leaves the liquid at 0mg, which is how some vapers use it.

As a rough guide for sub-ohm vaping, which uses large volumes of liquid per puff, lower strengths are usual. Around 3mg/ml suits many people who previously smoked a moderate amount, because the high airflow delivers a lot of nicotine per puff. Heavier former smokers sometimes find 3mg unsatisfying and move to 6mg, which is possible by using a larger bottle and two shots. Occasional vapers or people who vape mainly for flavour may prefer 0mg or a very light 1.5mg, which can be achieved by using a half shot or by adding the shot to a larger volume of liquid.

Two points are worth stressing. First, start low. Nicotine is addictive, and it is easier to add a little more than to take it back out. If you feel dizzy, nauseous or get a hot, harsh throat hit, the strength is too high for your setup. Second, do not use nicotine liquid if you do not currently use nicotine. Vaping is intended for adults who smoke or already use nicotine and want an alternative; it is not recommended for non-smokers or under-18s.

Freebase and nicotine salt shots behave differently. Freebase nicotine is the traditional choice for sub-ohm vaping and gives a standard throat hit. Nicotine salt shots, often sold at 20mg/ml, feel smoother at higher strengths but are usually intended for lower-power devices. For a 70VG liquid in a sub-ohm tank, freebase shots are the more usual pairing, so check what the shot you buy is designed for.

Remember that your own consumption changes the picture. Someone vaping 5ml a day at 3mg takes in roughly 15mg of nicotine daily, while someone vaping 2ml a day at the same strength takes in roughly 6mg. If you are unsure, pick the lower option and adjust over a week or two as you see how the strength feels.

How to Mix, Prime and Use It

Using a shortfill is simple once you have done it once. The steps below assume you are adding a single 10ml nicotine shot. If you are staying at 0mg, skip straight to filling your tank.

• 1. Prepare: wash your hands, work on a clean flat surface, and keep tissue nearby. Wear gloves if you have sensitive skin.
• 2. Open the bottles: twist off the Slow Blow cap, then open the nicotine shot.
• 3. Add the shot: squeeze the full contents of the shot into the 60ml bottle. Do not add more than one shot unless you have first removed liquid to make room.
• 4. Close and shake: replace the cap firmly and shake the bottle for around 30 seconds to mix the nicotine evenly.
• 5. Steep if you can: leave the bottle in a cool, dark place for 24 to 48 hours with the cap on. Shake once or twice during that time.
• 6. Fill the tank: follow your tank's instructions, fill below the maximum line and keep liquid out of the central airflow tube.
• 7. Prime the coil: for fresh coils, drip a few drops directly onto the cotton through the wicking holes, then wait 5 to 10 minutes before the first puff.
• 8. Start low: set the wattage at the lower end of the range printed on the coil and increase gradually.

Priming deserves emphasis. The most common reason a new coil tastes burnt is that the cotton was not saturated before it was fired. Thick 70VG liquid takes longer to soak through than thin 50/50, so give it the time it needs. Taking two or three gentle draws with the device switched off can help pull liquid into the coil.

When you vape, take slow, steady draws of three to five seconds rather than quick pulls. Longer draws let the coil refill between puffs and keep the temperature even. Pausing for 20 to 30 seconds between draws gives the wick time to catch up, particularly at higher wattages.

Look after your bottle between sessions. Keep the cap tight, store the bottle upright away from direct sunlight and heat, and wipe the nozzle after each fill. Never leave nicotine liquid within reach of children or pets, and label any decanted bottles clearly.

If you use more than one flavour, rinse your tank and replace the coil when switching, to avoid blended tastes. Cleaning with warm water and leaving the parts to dry fully before refilling is enough for most tanks. Keeping a small routine, such as a quick wipe of the threads and a check of the O-rings each time you refill, prevents most of the minor leaks and stuck-thread problems that people attribute to the liquid.

Coils, Tanks and Wattage: Matching the Hardware

A 70VG liquid wants a particular kind of hardware, and matching them correctly makes a larger difference to your experience than any other choice. In plain terms, you need a tank or atomiser with wide wicking channels, a coil designed for high-VG, and enough power to heat the liquid properly.

Coil styles that work well with Slow Blow include:

• Mesh coils: a flat sheet of fine metal mesh rather than a wound wire. Mesh has more surface area in contact with the cotton, so it heats evenly, wicks quickly and tends to preserve flavour. Common resistances run from roughly 0.15 to 0.3 ohm, typically at 40 to 80 watts.
• Wound sub-ohm coils: traditional round-wire coils around 0.2 to 0.5 ohm, usually rated for 30 to 70 watts. They are reliable and widely available, with a slightly warmer flavour.
• Restricted direct-to-lung (RDL) coils: around 0.4 to 0.8 ohm with tighter airflow. These sit between sub-ohm and mouth-to-lung and use less liquid, though extra-thick 70VG can still strain wicking on the higher resistances.

Whichever coil you choose, look at the printed wattage range and begin near the lower-middle of it. Running a coil at the top of its range burns through liquid and coils faster and tends to flatten fruit flavours. Running too low can leave the coil flooded, giving gurgling and weak flavour.

Tank size also matters for the practicalities. Refillable tanks sold in the UK are limited to 2ml of capacity under UK regulations, even though larger tanks are common in other countries. That means you will refill more often than the 50ml bottle size might suggest, so keep the bottle close and get used to topping up little and often rather than waiting until the tank is nearly empty. Letting a tank run dry is one of the quickest ways to scorch a coil.

Coil lifespan with a sweet, VG-heavy fruit liquid is usually somewhere between one and three weeks of regular use, depending on wattage and habits. Signs a coil is ready to be replaced include flavour fading, a slightly burnt or sour aftertaste, bubbling or crackling that was not there before, and darkened, gunky cotton when viewed through the wicking ports. Keeping the wattage moderate and letting the coil cool between draws extends its life.

If you are new to sub-ohm vaping, a beginner-friendly starter kit with a 0.3 to 0.6 ohm coil and adjustable airflow is a sensible starting point. Check the manufacturer's information on compatible liquids before buying, and confirm that it supports 70VG. Starter kits aimed at newcomers often carry a clear VG range on the coil head itself, which makes the match easy to confirm.

Batteries, Charging and Power Safety

Slow Blow does not have a battery of its own, because it is a liquid, but the battery in your device has a direct effect on how the liquid performs. High-VG liquid on sub-ohm coils draws far more current than a small pod kit does, so the battery and its charging habits matter.

Devices generally fall into two types. Kits with built-in batteries, such as many starter pens and all-in-one box mods, commonly carry capacities from about 1,000mAh to 3,000mAh and charge by USB-C. Mods with removable batteries use 18650 or 21700 cells, usually in the 2,500mAh to 5,000mAh range, and are charged either in the device or, preferably, in a separate external charger. As a rule of thumb, higher capacity gives longer run time between charges, and a higher continuous discharge rating allows the battery to deliver the current a sub-ohm coil demands.

To get safe and consistent performance:

• Match the battery to the coil: a battery's continuous current rating, in amps, must be high enough for your coil resistance and wattage. Your device's manual or a reputable battery-safety guide explains how to check this.
• Use the right charger: charge with the cable supplied, or a reputable branded USB charger of suitable output, and never with an unbranded charger of unknown quality.
• Do not charge unattended: do not leave a battery charging overnight or when you are out of the house.
• Keep loose cells protected: carry removable batteries in a plastic case, never loose in a pocket or bag with keys or coins.
• Inspect wraps: if a cell's plastic wrap is torn, damaged or peeling, stop using it and replace it.

Battery level can affect liquid performance subtly. As voltage falls on an unregulated or low-end device, the output can sag, leading to cooler vapour and duller flavour from the same liquid. Regulated devices maintain a steady wattage until the battery is almost flat, so flavour stays consistent across the charge. If Slow Blow suddenly tastes muted, check the battery before blaming the liquid.

Charging time varies between devices, but most USB-C built-in battery kits take roughly one to two hours to charge from empty. Faster external chargers will also shorten the time for removable cells, although slower charging is gentler on a battery over its lifespan.

Finally, at the end of its life, never throw a battery into household rubbish or standard recycling bins. Lithium-ion cells can start fires in bin lorries and waste facilities. Drop used batteries and vape hardware at a battery recycling point, which is available at many supermarkets, DIY retailers and local council household waste recycling centres. See the final section for more on recycling.

Who Slow Blow Suits and Who Should Skip It

Every liquid suits some vapers better than others. Here is a candid look at who is likely to enjoy Slow Blow and who might want to look elsewhere.

Slow Blow is a good match if you:

• already use a sub-ohm tank or a high-wattage refillable kit and want a fruit liquid designed for it;
• enjoy tropical or tart fruit rather than sweets, desserts or tobacco flavours;
• want the flexibility to choose your own nicotine strength, including 0mg;
• go through a lot of liquid and want a larger bottle to cut cost per millilitre;
• prefer a smooth, low-throat-hit vape with plenty of vapour.

You may want to look at something else if you:

• use a low-power pod kit or mouth-to-lung device that works best with thin 50/50 or nicotine salt liquid;
• need a strong throat hit, which high-VG blends at low nicotine do not provide;
• dislike sharp or tart notes and prefer very sweet, dessert-style profiles;
• want a menthol or ice finish by default;
• do not want to mix your own nicotine, in which case a ready-mixed 10ml nicotine bottle or a nicotine salt is simpler.

It is also an option for people moving on from single-use vapes. Many former disposable users are used to 20mg nicotine salt strength in a small pod, and the jump to a 3mg shortfill in a sub-ohm tank can feel quite different: more vapour, a smoother throat feel and less intense nicotine per puff. That does not mean it is weaker overall, because each puff uses much more liquid. It does mean the switch needs a little adjustment, and some people find they want to start nearer 6mg to compensate. Taking a week or two to find the right combination is normal.

Who should not buy this product at all? Anyone under 18, who cannot legally purchase or be sold nicotine liquid in the UK. Non-smokers who have never used nicotine should not start with a nicotine shot. Pregnant or breastfeeding people, and anyone with a heart condition or other health concerns, should speak to a doctor or pharmacist before using nicotine products. The NHS and local stop smoking services provide free advice if you are trying to quit smoking and want to compare options such as patches, gum and vaping.

Finally, if you only vape occasionally, a 50ml bottle may take months to finish. In that situation a smaller 10ml bottle may be a better fit, or you can store the mixed bottle carefully and use it within the date on the label.

Troubleshooting Common Problems

Most problems with a shortfill come down to wicking, priming, power or mixing rather than the liquid itself. Here is a quick diagnostic guide for the issues vapers report most often with high-VG fruit liquids.

• Burnt or acrid taste: usually an unprimed coil or a coil past its life. Replace the coil, prime it properly with a few drops and a 5 to 10 minute soak, and start at a lower wattage. Chain vaping can also burn a coil, so pause between draws.
• Dry hits: the wick is not getting enough liquid. Check the tank is not nearly empty, that the airflow is not too open, and that the coil's wicking holes are large enough for 70VG. Lowering the wattage often solves it.
• Gurgling or spitting: excess liquid is sitting in the coil chamber. Remove the tank, blow gently through the drip tip, wipe away liquid, and refill below the maximum line. Opening airflow slightly or reducing the wattage can help.
• Leaking: check that the O-rings are seated, the tank sections are screwed together firmly, and the tank is not overfilled. Leaks can also happen after a flight or when the tank is stored on its side.
• Weak or muted flavour: a tired coil, low battery or vaper's tongue (temporary flavour fatigue). Try changing the coil, charging the battery, drinking water and switching flavour for a day.
• Harsh throat hit: the nicotine strength is too high, or the wattage is too high for the coil. Reduce power or choose a lower strength next time.
• Sweet sticky residue: wipe the tank threads and drip tip regularly. Sugary build-up from VG-heavy fruit liquid can lead to stiff threads and cloudy glass.
• Liquid looks darker over time: a slight darkening in colour is normal for steeped e-liquid and nicotine-containing mixes. It is not a cause for concern unless the liquid smells off, separates visibly or becomes cloudy.

A useful habit is to change only one thing at a time. If you swap the coil, the wattage and the nicotine strength all at once, you will not know which change fixed or caused the problem. Make a single adjustment, vape for a tank, and judge the result.

When should you stop and contact someone? If a battery gets hot, swells, hisses or smokes, stop using it, move away from flammable material and follow your device manual or manufacturer advice. If a bottle arrives leaking or with a broken seal, stop and get in touch rather than trying to salvage it. If you have swallowed liquid or got it in your eyes, treat it as a medical matter and get urgent advice from NHS 111, or call 999 in an emergency.

Keep a few spare coils on hand so a worn coil does not interrupt your routine, and note down which wattage works well for each coil type so you can return to it quickly.

Value for Money and How It Compares

Value in e-liquid is best judged by cost per millilitre and by how long a bottle lasts in your own setup, not by sticker price alone. A 50ml shortfill is cheaper per millilitre than five 10ml bottles, so a daily vaper will usually spend less overall, although the upfront cost is higher and you need to add a nicotine shot as a separate purchase.

Here is a simple way to compare. Take the price of the Slow Blow bottle, add the price of one nicotine shot, and divide by 60 to get a cost per millilitre of finished liquid. Then do the same for a 10ml nicotine salt or freebase bottle by dividing its price by 10. Shortfills usually work out noticeably lower per millilitre, although the exact gap depends on current prices and on any multibuy offers, which are worth checking on the store page.

How long a bottle lasts depends on consumption. These are rough estimates for the finished 60ml bottle:

• 1ml a day: light use, roughly two months.
• 2ml a day: moderate use on a lower-power coil, roughly 30 days.
• 3ml a day: typical sub-ohm use, roughly 20 days.
• 5ml a day: heavy sub-ohm use, roughly 12 days.

Those numbers shift with wattage, coil and how often you vape, so use them as a starting point rather than a promise.

How does it compare with the alternatives? Honestly, it depends on what you value:

• Other 50ml fruit shortfills: many brands sell similar kiwi, passion fruit or guava combinations, and the differences come down to sweetness, the VG/PG split and how sharp the fruit is. Some UK-made ranges are priced similarly or slightly lower, and some lean sweeter or add menthol. Slow Blow's draw is its tart, tropical profile and the established Nasty Juice name; it is not the only option, and it is worth comparing prices and reviews.
• 10ml nicotine salt bottles: better for pod kits and mouth-to-lung devices, quicker to use with no mixing, but higher in cost per millilitre and not designed for sub-ohm tanks.
• Ready-mixed 10ml freebase bottles: no shot to add, but a smaller volume and typically a higher price per millilitre.
• Single-use vapes: these can no longer be sold in Great Britain following the ban that came into force on 1 June 2025, so refillable kits with bottled liquid, and rechargeable pod devices, are the practical route. Over time, a refillable setup also tends to cost less to run and produces less waste.

Overall, the value case rests on three points: a lower cost per millilitre than small bottles, the freedom to set your own nicotine level, and a flavour that holds up over a full tank. The compromises are the need for compatible hardware, the extra step of mixing, and a tart profile that will not suit every palate.

UK Rules, Storage and Recycling

Buying and using e-liquid in the UK is governed by the Tobacco and Related Products Regulations 2016, and knowing the basics helps you buy and store products sensibly.

• Age: it is illegal to sell nicotine vaping products to anyone under 18, and illegal for an adult to buy them on behalf of someone under 18. Expect age checks when ordering and sometimes on delivery.
• Bottle size: nicotine-containing e-liquid is limited to 10ml bottles. That is why Slow Blow ships at 0mg with a separate nicotine shot.
• Strength: the maximum nicotine strength for UK e-liquid is 20mg/ml. The same cap applies whatever the format, including nicotine salts.
• Tank size: refillable tanks are limited to 2ml capacity.
• Packaging: nicotine products must carry a health warning and be sold in child-resistant and tamper-evident packaging.

Good storage keeps the liquid tasting as intended and keeps everyone safe. Store bottles upright with the cap on, in a cool, dark place away from sunlight, heaters, car dashboards and windowsills. Heat and light can degrade the flavour and darken the liquid faster. Keep all e-liquid, nicotine shots and devices where children and pets cannot reach them. Nicotine is toxic if swallowed or absorbed through the skin in sufficient quantity. If liquid gets on your skin, wash it off with soap and water. If it gets in your eyes, rinse with clean water. If anyone swallows it, or you feel unwell after exposure, get urgent medical help by calling NHS 111, or 999 in an emergency. Mixed bottles are best used within the date on the label and within roughly a year, so make a note of the mixing date.

Recycling is the part that people forget. The bottles, batteries and devices all need different handling:

• Empty bottles: let any remaining liquid drain, then check your local council's guidance on whether small plastic bottles can go in kerbside recycling. If in doubt, take them to a household waste recycling centre.
• Nicotine shot bottles: treat these the same way, and do not pour leftover liquid down the sink or into the garden.
• Batteries: take used lithium-ion cells to a battery recycling drop-off point. These are found at most large supermarkets, DIY stores and council recycling centres.
• Vape devices and coils: these count as waste electrical equipment, so take them to a council recycling centre or a retailer that offers a take-back scheme, rather than putting them in general waste.

The aim is simple: buy from a reputable UK retailer, mix and store carefully, and dispose of the empties responsibly. It is a small amount of effort that keeps vaping safer and cleaner for everyone.
