Not all nicotine shots are created equal, and understanding the differences can significantly enhance your vaping experience. The two main considerations when choosing a nic shot are the type of nicotine it contains and its strength. Let's break down what makes each option unique and how to pick the right one for your needs.

Freebase Nicotine Shots

Freebase nicotine has been the standard in e-liquids for years. It's nicotine in its purest form, which means it delivers that classic, noticeable throat hit many vapers enjoy—particularly those who've recently made the switch from traditional cigarettes. When you add a freebase nic shot to your shortfill, you're getting a vaping experience that closely mimics the sensation of smoking, which can be quite satisfying.

Most freebase nic shots come in 18mg strength, which is the maximum legally available in the UK. These work brilliantly with shortfills, and they're particularly popular among cloud chasers using sub-ohm devices. The throat hit is more pronounced at higher wattages, giving you that satisfying "kick" at the back of your throat.

Nicotine Salt Shots

Nicotine salts represent a newer innovation in the vaping world. Unlike freebase nicotine, nic salts are absorbed more quickly by your body and provide a smoother throat hit even at higher concentrations. This makes them perfect for vapers who want their nicotine fix without the harshness that can sometimes come with freebase nicotine at higher strengths.

Typically available in 20mg strength (the maximum under TPD regulations), nicotine salt shots are an excellent choice for mouth-to-lung (MTL) vapers or anyone using lower-powered devices. They're also brilliant if you find freebase nicotine too harsh but still need adequate nicotine satisfaction to keep those cravings at bay. Many vapers who use pod systems or MTL tanks swear by nic salt shots for their smooth delivery and fast-acting nicotine absorption.

Strength Options Available

While 18mg freebase and 20mg nicotine salt shots are the most common, you'll also find other strengths available. Some brands offer 15mg, 12mg, and even 9mg options. These lower-strength shots are useful if you want to create e-liquid with nicotine concentrations between the standard levels—for instance, a 1.5mg or 2mg mix—or if you're gradually reducing your nicotine intake.

When selecting a nicotine shot, matching the VG/PG ratio to your shortfill is crucial for maintaining the intended vaping experience. VG (Vegetable Glycerine) and PG (Propylene Glycol) are the two base liquids in all e-liquids, and their ratio affects everything from vapour production to throat hit and flavour intensity.

Understanding VG and PG

VG (Vegetable Glycerine) is a thick, sweet liquid responsible for vapour production. Higher VG ratios produce bigger, denser clouds and offer a smoother inhale. However, VG is less efficient at carrying flavour than PG. It's perfect for sub-ohm vaping and direct-to-lung (DTL) styles where cloud production is desired.

PG (Propylene Glycol) is thinner and provides a stronger throat hit whilst carrying flavour more effectively. Higher PG ratios are better for mouth-to-lung (MTL) vaping and deliver more intense flavour. They're also better suited to smaller devices with tighter airflow.

Common VG/PG Ratios in Nic Shots

Most nicotine shots come in specific VG/PG ratios designed to complement popular shortfill blends:

• 70VG/30PG Nic Shots: The most popular option, perfect for matching high-VG shortfills commonly used in sub-ohm devices. These maintain the smooth, cloud-heavy experience most shortfill users are after.
• 50VG/50PG Nic Shots: A balanced option suitable for all-round vaping. These work well with mid-range devices and provide a good compromise between flavour, throat hit, and vapour production.
• 80VG/20PG or Higher: For maximum cloud production, some manufacturers offer ultra-high VG shots. These are ideal if you're using a shortfill with 80% VG or higher and want to maintain that thick, smooth vapour.

How VG/PG Affects Your Final Mix

When you add a 10ml nic shot to a 50ml shortfill, you're adding about 16.7% of the final volume. This means the nic shot's VG/PG ratio will influence your final blend, but not dramatically if you match it correctly. For example:

• A 70/30 shortfill mixed with a 70/30 nic shot remains 70/30
• A 70/30 shortfill mixed with a 50/50 nic shot becomes approximately 67/33
• A 70/30 shortfill mixed with an 80/20 nic shot becomes approximately 72/28

These small variations might not seem significant, but they can affect the overall vaping experience, particularly for experienced vapers who've fine-tuned their preferences.

Using nicotine shots is wonderfully straightforward, but there are a few best practices worth following to ensure you get the perfect mix every time whilst staying safe.

Step-by-Step Mixing Guide

1. Check Your Shortfill Size: Most shortfills come in 50ml or 100ml bottles with space left for nic shots. Make sure you know the size before adding your shot.
2. Choose Your Strength: Decide what final nicotine strength you want. Use the calculations in our mixing calculator section to work out how many shots you need.
3. Open Both Bottles: Remove the cap from your shortfill and your nicotine shot. Some shortfills have a nozzle that you'll need to remove first.
4. Pour Carefully: Tip the entire contents of your nic shot into the shortfill bottle. Take your time—nicotine is quite thin and can spill easily.
5. Secure the Cap: Replace the cap on your shortfill bottle and make sure it's tightly sealed.
6. Shake Thoroughly: Give the bottle a really good shake for at least 30-60 seconds. You want the nicotine to be evenly distributed throughout the e-liquid.
7. Steep if Necessary: Some e-liquids benefit from steeping (letting them sit for a few days) after mixing. This allows the flavours to fully blend with the nicotine. Check the manufacturer's recommendations.

Common Mistakes to Avoid

Even though mixing nic shots is simple, here are a few pitfalls to watch out for:

• Not Shaking Enough: Insufficient mixing can lead to inconsistent nicotine distribution, meaning some vapes might be stronger than others. Always shake thoroughly.
• Adding Too Many Shots: More isn't always better. Adding multiple shots to achieve higher strengths will dilute your flavour and alter the VG/PG ratio significantly.
• Using Mismatched Ratios: Using a nic shot with a very different VG/PG ratio to your shortfill can change the vaping characteristics you were expecting.
• Vaping Immediately After Mixing: Some e-liquids, particularly complex dessert or tobacco flavours, really benefit from a few days of steeping after adding nicotine. Be patient for the best results.

Storage and Shelf Life

Nicotine can degrade over time, especially when exposed to light, heat, or air. Store your nic shots and mixed e-liquids in a cool, dark place. Unopened nicotine shots typically have a shelf life of around 1-2 years, whilst mixed e-liquids are best used within 6-12 months for optimal freshness and flavour.

Quality matters when it comes to nicotine shots. At VapeBus, we only stock nic shots from reputable, TPD-compliant manufacturers who maintain rigorous quality standards. Here are some of the most popular and trusted brands in our collection:

Vampire Vape Nic Shots

Vampire Vape is a household name in UK vaping, renowned for their consistent quality and attention to detail. Their Nicit Up range includes freebase shots in various VG/PG ratios (50/50, 70/30, 80/20), nicotine salt options, and even ice-cold menthol variants for those who enjoy a cooling sensation. Vampire Vape nic shots are manufactured to exacting standards and are a reliable choice for vapers who want consistency every time.

Bar Juice Nicotine Shots

Bar Juice has quickly become a favourite among vapers who enjoy disposable-style flavours in a more economical format. Their nic shots are designed to work seamlessly with their extensive shortfill range, maintaining the authentic taste profiles their brand is known for. Available in both freebase and salt nicotine options.

Vapouriz Premium Nic Shots

Vapouriz Premium offers excellent value without compromising on quality. Their nic shots are TPD compliant, lab-tested, and available in the most popular strengths and ratios. They're a solid, no-nonsense choice for vapers who want a dependable product at a competitive price.

Just Juice Nicotine Shots

Just Juice specialises in fruit-forward e-liquids, and their nic shots are formulated to complement their vibrant flavour profiles. Available in standard strengths with carefully balanced VG/PG ratios, Just Juice shots are perfect for vapers who prioritise fruity, bold tastes.

Drifter Salt Nic Shots

For those who prefer nicotine salts, Drifter offers premium 20mg salt nic shots that deliver smooth, satisfying hits without harshness. These are particularly popular with MTL vapers and anyone using pod-style devices who wants quick nicotine absorption.

Nicotine shots have revolutionised the way UK vapers enjoy their e-liquids. Beyond just being a workaround for TPD regulations, they offer genuine advantages that make vaping more flexible, economical, and personalised.

Cost Savings

This is perhaps the most compelling benefit. Buying a 50ml shortfill with a nic shot works out significantly cheaper than purchasing six 10ml bottles of the same flavour with nicotine already mixed in. Over time, especially for regular vapers, these savings really add up. You're essentially getting five times the volume for roughly twice the price—that's excellent value for money.

Complete Customisation

Fancy a 3mg strength today but 6mg tomorrow? No problem. Want to try switching from freebase to salt nicotine to see which you prefer? Easy. Nicotine shots give you total control over your vaping experience. You can adjust strength, choose between nicotine types, and even gradually reduce your nicotine intake by using fewer shots over time.

Fresher E-Liquid

Because shortfills come without nicotine, they tend to have a longer shelf life before being opened. The flavour stays fresher for longer in storage. When you add your nic shot, you're creating a fresh batch of nicotine-containing e-liquid that's at peak quality. It's like mixing a cocktail fresh rather than buying one ready-made that's been sitting on the shelf.

Greater Flavour Selection

The shortfill market offers an absolutely enormous range of flavours, far exceeding what's available in pre-mixed 10ml bottles. From complex dessert blends to exotic fruits and unique cocktails, there's virtually no limit to what you can try. Nicotine shots unlock this entire world of flavour possibilities.

Ideal for DIY Mixers

If you enjoy making your own e-liquids at home, nicotine shots are the only legal way to add nicotine to your creations in the UK. They provide a safe, measured way to incorporate nicotine into your DIY recipes without needing to handle pure nicotine base, which requires special storage and handling.

Environmental Benefits

Using larger shortfill bottles means less packaging waste compared to buying multiple small bottles. Whilst this might seem like a minor point, for regular vapers who go through substantial amounts of e-liquid, it does contribute to reducing plastic waste over time.

At VapeBus, we offer various e-liquid categories beyond just nicotine shots and shortfills. Understanding how nic shots fit into the broader e-liquid landscape can help you make better choices for your vaping setup.

Nicotine Shots + Shortfills

This is the classic pairing. Shortfills are specifically designed with nic shots in mind—they're large bottles of 0mg e-liquid with space left at the top for you to add your nicotine. The flavours are typically more concentrated to account for the dilution that occurs when you add the shot. This combination offers the best value and widest flavour selection.

Most shortfills are high-VG blends (70% VG or higher), making them perfect for sub-ohm tanks and devices that produce large clouds. When mixing nic shots with shortfills, always check the recommended ratio to ensure you're getting the vaping experience the manufacturer intended.

Comparing with Nicotine Salts

Nicotine salt e-liquids come pre-mixed with nic salts already blended in, typically in 10ml or 20mg bottles. These are convenient ready-to-vape options, particularly for MTL devices and pod systems. Unlike shortfills, you don't need to add anything—just fill your tank and go.

However, if you want to use nic salts with shortfills, that's where nicotine salt shots come in. They give you the smooth delivery of nic salts whilst maintaining the cost benefits and flavour variety of shortfills. It's the best of both worlds.

Freebase Nicotine E-Liquids

Traditional freebase nicotine e-liquids are pre-mixed bottles that contain freebase nicotine, usually in 10ml sizes with strengths ranging from 3mg to 18mg. These are completely ready to use straight out of the bottle—no mixing required.

The main difference between using freebase e-liquids and adding freebase nic shots to shortfills is simply convenience versus value. Pre-mixed bottles are grab-and-go easy but more expensive per millilitre. Nic shots require a bit of mixing but save money and offer more choices.

Which Option Is Right for You?

If you're someone who vapes regularly and goes through e-liquid quickly, shortfills with nic shots offer unbeatable value. If you prefer convenience and don't mind paying a bit extra, pre-mixed bottles might suit you better. Many vapers keep both options on hand—shortfills for their everyday favourites and pre-mixed bottles for trying new flavours or when they need something quick.

Safety is absolutely paramount when it comes to nicotine products. At VapeBus, we take quality control seriously and only stock nicotine shots that meet stringent UK and EU regulations.

TPD Compliance

Choosing Quality Products

When shopping for nicotine shots, look for these quality indicators:

• Established, reputable brand names
• Clear batch numbers and expiry dates
• Proper TPD-compliant labelling
• Childproof caps and tamper-evident seals
• Retailers who provide detailed product information

At VapeBus, we carefully vet every brand we stock to ensure they meet these criteria. Your safety and satisfaction are our top priorities.

Even with straightforward products like nicotine shots, questions and occasional issues can arise. Here are solutions to the most common problems vapers encounter:

Problem: Harsh Throat Hit After Mixing

If your e-liquid feels too harsh after adding a nic shot, several factors might be at play:

• Too much nicotine: You may have added more nicotine than you're comfortable with. Consider using a lower-strength shot next time or fewer shots total.
• Needs steeping: Some e-liquids require a few days for the nicotine to fully integrate. Let your mix sit for 3-5 days and try again.
• Wrong nicotine type: Freebase nicotine naturally has a stronger throat hit. Try switching to nicotine salt shots for a smoother experience.
• High PG content: PG contributes to throat hit. If your nic shot has higher PG than your shortfill, this could increase harshness.

Problem: Weak or Muted Flavour

If flavour intensity drops after mixing:

• Over-dilution: Adding too many nic shots dilutes the flavour concentration. Stick to recommended amounts.
• Wrong VG/PG ratio: Using a nic shot with significantly different ratio can affect flavour delivery. Match ratios closely.
• Vaper's tongue: Extended vaping of the same flavour can dull your taste perception. Switch flavours for a while.
• Needs steeping: Some complex flavours develop more depth after steeping for a week or two.

Problem: E-Liquid Too Thin or Thick

Consistency issues usually stem from VG/PG mismatches:

• Too thin: You've likely added a high-PG nic shot to a high-VG shortfill. This can cause leaking in some tanks. Next time, use a nic shot that matches your shortfill's ratio.
• Too thick: The opposite problem—high-VG shot in a balanced shortfill. This might cause wicking issues. Again, matching ratios is key.

Problem: Nicotine Feels Too Strong or Too Weak

Getting the strength right takes some experimentation:

• Too strong: Use fewer shots, try lower-strength shots (15mg or 12mg instead of 18mg), or choose larger shortfills to dilute further.
• Too weak: Add an additional shot, use higher-strength shots, or switch to nicotine salts which absorb more efficiently.

Problem: Separation or Cloudiness

If your mixed e-liquid looks separated or cloudy:

• Insufficient mixing: Shake more vigorously for at least 60 seconds.
• Temperature: VG can become cloudy when cold. Let it warm to room temperature and shake again.
• Old product: Check expiry dates on both the shortfill and nic shot.
