What Are Nic Salts?

Nic Salts Explained at a Glance

Nic salts are a refined type of nicotine used in e-liquids for smoother, faster absorption. They’re created by combining nicotine with mild organic acids, which makes the vapour easier to inhale and steady in strength. Here’s a quick, clear overview of how they behave in real use:

• Nic salts form a stable compound that delivers nicotine quickly in compact pod systems.

• Their chemistry reduces the throat harshness you often feel with traditional freebase liquids.

• When heated, they release nicotine that’s absorbed efficiently through the lungs, giving a controlled and satisfying experience for adults who already use nicotine.

• They’re regulated under UK TPD rules, which limit nicotine strength, bottle size, and labelling. Products aren’t risk-free and should only be used by adults.

• Buying TPD-compliant nic salt e-liquids from trusted retailers like Vape Big helps you avoid counterfeit or unsafe products.

• Freebase nicotine feels sharper because it’s more alkaline, while nic salts feel smoother and more consistent on each inhale.

• Freebase is better for high-wattage sub-ohm devices. Nic salts work best in low-powered MTL pod kits and starter vapes that use higher-resistance coils.

• High-wattage or sub-ohm devices aren’t recommended for nic salts because they can deliver too much nicotine too quickly.
  
  

Understanding Nic Salts

Nicotine salts perform differently from traditional e-liquids because of how they’re made. When nicotine reacts with specific organic acids, it changes its chemical structure, creating a more balanced compound that behaves differently when vaporised. This process affects everything from vapour feel to how quickly nicotine is absorbed, giving nic salts their distinctive performance.

Let’s look at the chemistry that makes this possible and how it shapes the vaping experience.

What Is Nicotine Salt?

Nicotine salt, or nic salt, is a form of nicotine that exists naturally in tobacco leaves. In this state, nicotine molecules are paired with organic acids, which stabilise them. To produce nic salts for e-liquids, manufacturers replicate this by combining purified nicotine with a mild acid such as benzoic, lactic, or levulinic acid.

This creates a more stable, less volatile compound that vaporises evenly and retains strength at lower temperatures. Because of this, nic salts deliver consistent nicotine levels while producing a smoother vapour that’s easier to inhale at moderate power.

Acids in Nic Salts

The addition of organic acids is what separates nic salts from freebase nicotine. These acids lower the pH of the e-liquid, making the vapour gentler on the throat and lungs. Beyond comfort, they also influence how nicotine behaves during heating, promoting stable vapourisation and helping preserve flavour quality.

Different acids are used for different results:

• Benzoic acid helps the nicotine absorb more easily in the lungs, so the effects are felt more quickly and evenly.

• Lactic acid focuses on smoothness, reducing any remaining throat sharpness.

• Levulinic acid can add a slight sweetness and enhance flavour clarity.

Together, they fine-tune both the feel and efficiency of the vaping experience.

Nic Salt Absorption

Once inhaled, nicotine salts are rapidly absorbed through the lungs into the bloodstream. Their altered chemical form allows nicotine to cross biological membranes more effectively than traditional freebase liquid, resulting in consistent, predictable delivery.

This faster uptake means users feel the effects sooner, without needing to inhale large volumes of vapour. Because of that balance, nic salts pair best with compact pod systems or mouth-to-lung (MTL) devices, which are designed to replicate the natural draw of a cigarette while maintaining control over nicotine output.

For users fine-tuning their e-liquid preferences, the Nicotine Shot Calculator can help achieve the ideal nicotine strength for comfort and satisfaction.

Choosing Nic Salt Strength

Understanding nic salt strengths is key to finding a satisfying vape without overdoing nicotine intake. In the UK, e-liquids are legally capped at 20 mg/ml under the Tobacco and Related Products Regulations (TPD), meaning all nic salts must fall below this limit. Most brands offer 5 mg, 10 mg, and 20 mg options, making it easier to match your vaping strength to your previous smoking habits.

Let’s look at the main strengths available and how to choose what suits you best.

Nic Salt Strength Options

Nic salts come in a few standard strengths, each catering to different levels of nicotine need:

• 5 mg/ml: Best for light smokers or social vapers who want mild satisfaction without strong nicotine.

• 10 mg/ml: A balanced middle ground for moderate smokers who used to have around half a pack a day.

• 20 mg/ml: The strongest option allowed in the UK, designed for heavy smokers or those who want quick relief from cravings.

These levels allow gradual adjustment; many users start higher and gradually reduce as cravings decrease.

Here’s a simple guide to help you choose your starting point:

This is only a guideline; personal tolerance, device type, and puff frequency all play a role. If you find yourself vaping constantly, you may need a slightly higher strength; if it feels too strong or harsh, step down.

Tips for Adjusting Nicotine Levels

Finding the right strength can take some trial and error. Start at the level closest to your smoking habit, then adjust after a few days. Signs you might need to lower your nicotine include light-headedness, throat discomfort, or reduced enjoyment.

For precise adjustments or DIY mixing, try our Nicotine Strength Calculator to tailor your e-liquid safely and within UK limits.

Best Devices for Nic Salts in the UK

Nic salts perform best in low-wattage, high-resistance devices that prioritise flavour and control over power and vapour volume. These setups allow higher nicotine strengths to be vaped comfortably while maintaining a consistent draw. In the UK, pod systems and mouth-to-lung (MTL) kits remain the top choices for smooth, efficient salt-based vaping.

Pod Kits and Nic Salts

Pod kits are compact, user-friendly vapes that heat e-liquid at lower wattages, delivering gentle vapour without overwhelming nicotine output. They often use MTL (mouth-to-lung) coils, which replicate the draw of a cigarette, you inhale into your mouth first, then into your lungs.

This tighter airflow and lower vapour production make MTL devices ideal for higher nicotine strengths and flavour clarity. They’re efficient, discreet, and perfect for ex-smokers or anyone who wants reliable performance without large clouds.

Nic Salt Pods: Refillable vs Prefilled

Modern pod kits come in two main types: refillable and prefilled.

• Refillaable pods let you add any nic salt e-liquid you like, offering flexibility in flavour and strength. They’re generally more cost-effective over time and generate less waste, as only the coil or pod needs replacing.

• Prefilled pods arrive ready to use and are great for simplicity or travel, though they cost slightly more per use and create more disposable plastic.

Refillable pods are the better choice for regular vapers who value long-term savings and eco-conscious design, while prefilled pods suit beginners who want an easy, mess-free start.

How to Use Nic Salts

Nic salts are easy to use, but getting the best experience depends on proper setup and mindful use. Using the right device settings, maintaining your pod or tank, and handling liquids correctly all help ensure smooth performance and safe nicotine delivery.

Follow these tips to get the most from your nic salt e-liquid while keeping your device, and yourself, in top condition.

Filling and Priming Your Pod for Nic Salts

To get clean flavour and avoid dry hits, follow these quick steps before your first vape:

1. Check your coil and pod.
Make sure you’re using the correct coil for nic salts, usually between 1.0Ω and 1.8Ω, and that it’s securely fitted into the pod or tank.

2. Prime your coil.
Add 2–3 small drops of nic salt e-liquid directly onto the cotton inside the coil. This pre-soaks the wick to prevent burning when you first fire the device.

3. Fill the pod or tank.
Open the fill port and slowly add e-liquid up to the indicated line. Avoid overfilling to prevent leaks or flooding.

4. Wait and settle.
Let the filled pod sit for 5–10 minutes so the coil can absorb the liquid completely.

5. Take a few gentle puffs without activating the device (optional).
This helps draw liquid through the coil for extra priming before you start vaping.

6. Vape and enjoy.
Once ready, reattach the pod, check airflow settings if available, and start at a low wattage for smooth, consistent vapour.

Tip: Refill your pod before the liquid level gets too low. Keeping the cotton inside the coil soaked prevents dry hits and helps your coil last longer.

Nic Salts: Best Wattage & Coil Range

Nic salts perform best at low wattages with higher-resistance coils, typically between 1.0Ω and 1.8Ω. This setup limits vapour output and heat, making each puff smooth and satisfying without excessive nicotine delivery.

Avoid using nic salts in high-wattage or sub-ohm devices, as they can deliver too much nicotine too quickly and cause discomfort. Always check your device’s recommended settings before use.

How Often to Vape Nic Salts

Because nic salts absorb quickly, you won’t need to vape as frequently as with standard e-liquids. Try spacing sessions 10–15 minutes apart to prevent nicotine overconsumption.

If you feel light-headed, dizzy, or nauseous, pause your session and lower your nicotine strength next time. Listen to your body, satisfaction, not excess, is the goal.

Storing Nic Salts Safely

Store your nic salt e-liquids in a cool, dry place away from direct sunlight and out of reach of children or pets. Always replace the cap securely to prevent spills and oxidation.

Dispose of empty bottles and pods through recycling or household waste, following local guidance. Never pour leftover e-liquid down the drain. Responsible handling protects both users and the environment.

What ingredients are in Nic Salts 

Nicotine salt e-liquids use simple, regulated ingredients designed for adult vapers under UK law. Every product sold must meet strict standards for composition, nicotine strength, labelling, and packaging. Recent updates from the UK government on vape regulations reinforce these rules, including new measures such as the ban on single-use vapes from June 2025. Below, we explain what nic salts contain, how these regulations protect consumers, and address common questions about their composition and use.

Nic salt e-liquids contain only a handful of carefully controlled ingredients:

• Propylene Glycol (PG): A thin, flavour-carrying base that provides throat hit and helps evenly distribute nicotine.

• Vegetable Glycerine (VG): A thicker, plant-derived liquid that adds smoothness and produces vapour.

• Flavourings: Food-grade concentrates used to create everything from classic tobacco to fruit or dessert profiles.

• Nicotine: The active ingredient that provides satisfaction and helps reduce cigarette cravings.

• Organic Acids (e.g., Benzoic or Lactic Acid): Used to stabilise nicotine and create the smoother feel that defines nic salts.

All ingredients used in UK-compliant e-liquids must meet pharmaceutical or food-grade quality standards and follow the MHRA’s official guidance on e-liquid ingredients (published on GOV.UK). Each product must also be notified to the Medicines and Healthcare products Regulatory Agency (MHRA) before it can be legally sold in the UK.

Benefits and Drawbacks of Nic Salts

Nic salts offer distinct advantages for many adult vapers, but they’re not ideal for every device or preference. Their formulation provides comfort and speed, yet the same qualities that make them smooth can also limit flexibility for advanced users. Understanding the pros and cons of nic salts helps you decide whether they suit your vaping goals and setup.

Nic Salt Advantages

Nic salts are valued for their balanced performance and ease of use. Their lower pH produces a mild vapour that’s comfortable even at higher nicotine strengths, making them ideal for those moving away from smoking or seeking quick craving relief.

Because they vaporise efficiently at lower temperatures, nic salts deliver consistent nicotine delivery without the need for high power or large clouds. This makes them well-suited to smaller pod systems that prioritise convenience and portability.

Other practical advantages include:

• Stable shelf life: Nic salts degrade more slowly than freebase liquids, helping maintain flavour and potency over time.

• Discreet use: The vapour dissipates quickly, leaving minimal scent. Ideal for indoor or low-profile vaping.

• Smoother adjustment: Easier for new users to find a satisfying level without irritation.

When to Avoid Nic Salts

While nic salts perform well in everyday pod kits, they’re less compatible with powerful or sub-ohm devices. Their higher nicotine concentration can feel overwhelming when used with high-wattage coils that produce large vapour volumes.

They also provide a lighter throat hit, which may feel too gentle for vapers who enjoy a stronger kick or prefer more tactile feedback. Additionally, because nic salts are designed for faster absorption, some users may find themselves reaching for their device more often to maintain satisfaction.

Choosing between nic salts and freebase nicotine ultimately comes down to your device, vaping habits, and personal preference, which we’ll explore next.

Nicotine salts aren’t just a trend; they’re designed to suit specific vaping needs and lifestyles. Their smooth delivery and higher nicotine strength make them ideal for adult smokers switching to vaping or anyone seeking quick, satisfying nicotine in a simple format. However, they’re not the right choice for every vaper or device setup.

Below, we break down who benefits most from nic salts and when you might want to consider other options.

Who Should Use Nic Salts?

Nicotine salts are designed for specific vaping needs. Their smooth delivery and higher nicotine strength make them ideal for adult smokers switching to vaping or anyone who wants quick, satisfying nicotine in a simple format. However, they’re not suited to every vaping style or device setup.

Nic Salts for Smokers Switching to Vaping

Nic salts work well for smokers moving to vaping because they closely replicate the satisfaction and speed of nicotine from a cigarette. The smoother throat hit allows higher strengths without irritation, reducing cravings and making the switch easier. Used with compact pod kits, they offer a familiar, low-maintenance experience.

Nic Salts for New Vapers

For beginners who find standard e-liquids too mild, nic salts deliver a more concentrated nicotine effect that’s felt almost immediately. Their smoothness at higher strengths helps users manage cravings without frequent puffing or multiple devices.

Nic Salts for Discreet Vaping

Nic salts suit vapers who value convenience and discretion. Their low vapour output and quickly fading aroma make them ideal for commuting or shared spaces. Paired with small pod systems, they provide satisfying performance without drawing attention.

Who Nic Salts Aren’t Right For

Nic salts don’t suit every vaping style. They’re not ideal for people who use powerful, cloud-producing vape kits or enjoy experimenting with settings and custom coils. Those setups work best with lower-strength, freebase e-liquids, which can withstand higher heat and produce larger clouds of vapour.

If you prefer a strong throat hit, bold flavour, or large vapour production, you’ll get better results with freebase nicotine than with nic salts.

Nic Salts vs Freebase Nicotine

Both nic salts and freebase nicotine deliver the same substance, nicotine, but in very different ways. Their chemical structures, device compatibility, and overall vaping experience set them apart. Understanding these differences helps you choose which option best matches your preferences, whether that’s a stronger throat hit or a smoother, more cigarette-like inhale.

Nic Salts vs Freebase Smoothness

The throat hit is where most vapers first notice a difference.

Freebase nicotine has a higher pH, giving it a sharper, more pronounced sensation at the back of the throat. Many experienced users enjoy this intensity, especially at lower nicotine strengths, as it feels similar to smoking a strong cigarette.

Nic salts, by contrast, are chemically balanced with mild acids that lower alkalinity. This produces a softer, smoother inhale, comfortable even at higher nicotine levels. For beginners or those switching from smoking, this gentler feel often makes the transition easier.

Nic Salts vs Freebase: Absorption

The chemical balance of each nicotine type affects how quickly it’s absorbed.

Nicotine salts enter the bloodstream more quickly, providing near-instant satisfaction and helping curb cravings. This rapid uptake is one reason they’re commonly used in pod systems designed for efficiency.

Freebase nicotine absorbs more slowly, delivering a slower, longer-lasting release between puffs. It suits vapers who prefer steady use throughout the day rather than a fast nicotine hit.

Nic Salt vs Freebase Strength

Nic salts can comfortably deliver higher strengths (up to the UK legal limit of 20 mg) without overwhelming the throat. They’re best for new vapers or ex-smokers seeking a satisfying, cigarette-like nicotine level in a compact device.

Freebase e-liquids are usually preferred at 3–12 mg, where flavour and vapour production shine. They appeal to hobbyist vapers who value control, cloud production, and longer sessions over nicotine intensity.

Best Devices for Nic Salts and Freebase

Your vape device has a major impact on how nic salts and freebase nicotine perform.

Nic salts work best in low-powered, mouth-to-lung (MTL) pod kits or starter vapes using coils between 1.0 Ω and 1.8 Ω. These setups produce moderate vapour and smooth, consistent nicotine delivery.

Freebase nicotine e-liquids, however, are suited to sub-ohm and high-wattage devices. These produce large clouds and stronger throat hit but can make high-strength liquids feel harsh. Using nic salts in these powerful devices can result in excessive nicotine intake and discomfort.

Nic Salts vs Freebase: Flavour and Vapour

Flavour and vapour production differ noticeably between nicotine salts and freebase e-liquids.

Freebase nicotine produces richer flavour intensity and thicker clouds, especially at higher temperatures. It’s ideal for vapers who enjoy strong taste, visible vapour, and open airflow setups. However, sweet or dessert-style flavours can sometimes feel more pronounced or linger longer in the air.

Nicotine salts, by contrast, deliver cleaner, smoother flavour at lower wattages. They perform well in compact pod systems, bringing out subtler blends like fruits or menthols without overwhelming sweetness. Vapour dissipates faster, making nic salts more discreet for everyday use.

Nic Salts vs Freebase Nicotine – Quick Comparison

To make it easier to see how nic salts and freebase nicotine differ, here’s a quick side-by-side comparison. This table highlights the key differences in chemistry, performance, and device suitability, helping you choose the option that best fits your vaping style.

Overall, nic salts are best for vapers who want smooth, high-strength nicotine and cigarette-like satisfaction in smaller devices. Freebase nicotine suits those who enjoy lower strengths, bolder flavour, and larger vapour clouds. Knowing these differences helps you choose the right e-liquid for both comfort and performance.

Nic Salts vs Bar Salts vs Hybrid E-Liquids

Since the UK ban on single-use vapes took effect on 1 June 2025, the vaping market has shifted towards refillable, compliant alternatives. Products like bar salts and hybrid e-liquids have grown in popularity, offering the same smooth satisfaction and bold flavours that disposable users enjoyed, but in reusable, environmentally responsible formats.

While all three types use nicotine in liquid form, they each behave slightly differently when vaped. Here’s how nic salts, bar salts, and hybrid e-liquids compare in flavour, feel, and performance.

What Are Bar Salts?

Bar salts are a style of nicotine salt e-liquid formulated to recreate the sweet, intense flavours and smooth inhale that people associate with pre-ban disposable vapes. Instead of coming in a single-use device, bar salts are designed for use in legal refillable pod kits.

They typically use higher flavour concentrations and a balanced PG/VG ratio (often 50/50) to deliver a bold, saturated taste with a soft inhale. Chemically, they’re still nicotine salts, usually made using benzoic or lactic acid to keep the throat feel comfortable at higher strengths. Still, the emphasis is on strong, “disposable-style” flavour in a reusable format.

Bar salts are a good option for adult vapers who previously relied on disposables and now need a refillable alternative that feels familiar, stays within UK regulations, and avoids the waste and legal issues of single-use vapes. 

What Are Hybrid E-Liquids?

Hybrid e-liquids combine freebase nicotine and nicotine salts in one blend, offering the best of both worlds, a gentle throat hit with a satisfying nicotine delivery.

• The nic salt component provides smoothness and rapid absorption.

• The freebase portion adds a stronger hit and sharper flavour definition.

This balance appeals to users who find regular nic salts too soft but want faster relief than freebase alone. Hybrids perform well in low-to-mid-powered MTL pod systems, offering a flexible option for everyday vaping.

Nic Salts vs Bar Salts vs Hybrid E-Liquids - Comparison Table

To help you decide which liquid suits your style, here’s a quick comparison of how each type performs:

Bar salts are essentially flavour-boosted nic salts that recreate the intensity of disposable vapes, while hybrid e-liquids blend freebase and nic salts for a balanced feel. Standard nic salts remain the go-to for smooth, cigarette-like satisfaction, but the newer options give vapers more control over flavour, strength, and overall experience.

FAQs About Nic Salts – Quick Answers to Common Questions

Still have questions about nic salts? You’re not alone, they’re one of the most talked-about e-liquid types in the UK. Below, we’ve answered the most common questions adult vapers ask about how nic salts work, how to use them safely, and how they compare with other e-liquid styles.

What are nic salts?

Nic salts, or nicotine salts, are e-liquids made by blending nicotine with mild organic acids such as benzoic or lactic acid. This process creates a smoother, more stable form of nicotine that delivers satisfaction quickly without the harshness often associated with freebase e-liquid. Nic salts allow higher nicotine strengths to be used comfortably, making them ideal for adults switching from cigarettes to vaping. Because they mimic the natural form of nicotine found in tobacco leaves, they provide a familiar and balanced experience for transitioning smokers.

How do nic salts work?

Nic salts work by lowering the pH of the e-liquid, allowing nicotine to vaporise more efficiently at lower temperatures. When inhaled, this vapour is absorbed into the bloodstream more quickly than freebase nicotine, providing a quicker sense of satisfaction. The smoother vapour and faster absorption make nic salts perfect for small pod kits and mouth-to-lung devices. This efficient delivery means fewer puffs are needed to feel satisfied, helping reduce the urge to vape frequently.

What acids are used in nic salts?

Most nic salts are made from benzoic acid, but other acids, such as lactic and levulinic acids, are also common. These acids reduce nicotine’s alkalinity, making the vapour smoother on the throat and easier to inhale. They also help stabilise the nicotine, improving flavour and extending shelf life. The choice of acid can slightly influence the vaping feel. For example, benzoic acid offers a soft draw, while lactic acid gives a slightly sharper hit.

Are nic salts the same as nicotine salts?

Yes, “nic salts” is simply a shorter name for nicotine salts. Both terms refer to the same type of e-liquid that combines nicotine with organic acids for smoother delivery. This naming convention is standard across UK vape retailers and packaging. Whether the label reads 'nic salts' or 'nicotine salts,' the product works the same way and follows the same safety regulations.

Are nic salts safer or more addictive?

Nic salts are not risk-free and should only be used by existing adult smokers or vapers. They contain nicotine, which is an addictive substance, but their safety is regulated under the UK’s Tobacco and Related Products Regulations (TPD). According to public health research, vaping poses significantly fewer risks than smoking, yet it’s still intended as a nicotine alternative,  not a harmless product. Always purchase from trusted retailers to ensure your e-liquids are TPD-compliant and authentic.

Can I use nic salts in a sub-ohm vape?

No,  nic salts should not be used in sub-ohm or high-wattage vape devices. These devices deliver large amounts of vapour, which can result in excessive nicotine intake and throat discomfort. Nic salts are designed for low-power, mouth-to-lung pod kits that replicate the feel of a cigarette draw. For sub-ohm vaping, choose lower-strength freebase e-liquids instead.

Do nic salts have more nicotine?

Nic salts don’t contain more nicotine than other e-liquids; they just deliver it more efficiently. Under UK law, all e-liquids are capped at 20 mg/ml of nicotine, regardless of type. The key difference is that nicotine salts absorb more quickly, delivering a quicker, smoother hit. This makes them feel stronger than a comparable freebase e-liquid, even though the nicotine content is the same.

What are bar salts or hybrid e-liquids?

Bar salts are a type of nic salt e-liquid formulated to mimic the taste of disposable vapes, offering sweet, cooling flavours for refillable pod kits. Hybrid e-liquids combine freebase and nic salt nicotine, balancing smoothness with a slightly stronger throat hit. Both are designed for adults who want disposable-style flavour without waste or high cost. Vape Big stocks several bar salt ranges, including ElfLiq, Bar Juice 5000, and Maryliq.

How long do nic salts last?

A 10 ml bottle of nic salts typically lasts 2 to 5 days, depending on your device's power, coil resistance, and how frequently you vape. Because nic salts provide stronger satisfaction per puff, users often find they use less liquid overall. Pod systems are especially efficient, as they vaporise smaller amounts of e-liquid compared to sub-ohm kits. Always monitor usage to find your ideal pacing and strength.

What devices are best for nic salts?

Nic salts work best in pod kits or mouth-to-lung (MTL) vape pens with coils between 1.0 Ω and 1.8 Ω. These devices create a restricted airflow, similar to a cigarette draw, and gently heat e-liquid for smooth vapour. Popular MTL devices include the Vaporesso XROS, OXVA Xlim, and Aspire Gotek X. Avoid using nic salts in high-wattage or direct-lung systems.

What are the best nic salt flavours?

The UK market offers a wide range of nic salt flavours, from classic tobacco and menthol to fruit and dessert blends. Popular picks include ElfLiq Blue Razz Lemonade, IVG Strawberry Watermelon, and Nasty Salts Cush Man Mango.

Can nic salts expire?

Yes, most nic salt e-liquids have a shelf life of around two years from the manufacturing date. Over time, exposure to heat, air, or light can degrade nicotine and flavour quality. To keep them fresh, store bottles upright in a cool, dark place. Always check the expiry date printed on the packaging before use.

Are nic salts legal in the UK?

Yes, nicotine salts are entirely legal and regulated under the UK’s Tobacco and Related Products Regulations (TPD). These laws restrict nicotine strength to 20 mg/ml and bottle size to 10 ml, while requiring childproof caps and accurate labelling. All Vape Big products meet these standards to ensure compliance and consumer safety. Remember: these e-liquids are strictly for adults aged 18 and over.

Do nic salts stain coils or tanks?

Not typically. Nic salts behave much like standard e-liquids in this regard, but darker or sweeter flavours can leave more residue over time. Regular cleaning or coil replacement keeps the flavour crisp and performance consistent. If you notice a burnt taste or reduced vapour, it’s time to swap the coil.

Can I mix nic salts with other e-liquids?

Yes, you can mix nic salts with other 50/50 VG/PG e-liquids to adjust flavour or strength. Just avoid combining them with high-VG shortfills made for sub-ohm vaping, as this can affect consistency and performance. Mixing similar blends helps maintain smoothness, flavour, and coil life. Always shake well before filling your pod or tank.

Are nic salts suitable for beginners?

Absolutely. Nic salts are ideal for adults switching from smoking who want fast nicotine satisfaction without harshness. They’re easy to use with simple pod systems and come in many strengths and flavours. This balance of comfort, convenience, and performance makes them one of the most beginner-friendly vaping options available.
