Vaping isn’t just a way to quit smoking anymore—it’s a full-blown lifestyle. And if you’re even slightly interested in personalising your vaping experience, you’ll quickly hear about nicotine shots, or nic shots as they’re often called. They’re the behind-the-scenes heroes that give you complete control over how strong (or smooth) your vape hits. But what sets everyday vapers apart from the pros is how they mix nicotine shots into their custom vape juice setups.
In this blog, we’ll go beyond the usual beginner advice and explore how seasoned vapers, hobbyists, and vape shop staff go about mixing nicotine shots professionally—all while keeping the process accessible to anyone who wants to give it a try. Whether you're new to vaping or just want to up your game, this guide will help you mix like a pro, even if you're still learning the ropes.
What Are Nicotine Shots, Really?
Before we dive into mixing like a pro, let’s get the basics out of the way. Nicotine shots are 10ml bottles of nicotine e-liquid with a high nicotine concentration, typically 18mg or 20mg per millilitre. They’re unflavoured and designed to be mixed with shortfill e-liquids—which are larger bottles of vape juice that don’t contain nicotine but leave room for you to add your own.
There are two types of nicotine boosters:
- Freebase nicotine shots – known for a stronger throat hit and slower absorption.
- Nicotine salt shots (nic salt shots) – smoother with faster absorption, ideal for higher nicotine levels.
Understanding the type of nicotine shot you’re working with is key to getting the right outcome in your custom vape mix.
Why Do Professionals Custom-Mix E-Liquids?
Let’s be honest. Pre-mixed e-liquids are fine for casual users. But for those of us who really enjoy vaping—whether it's for stress relief, flavour crafting, or smoking cessation—custom mixing with nic shots offers several benefits:
- Personalised nicotine strength
- Wider flavour choices
- Cost efficiency
- Control over throat hit and vapour production
- Smooth transition off cigarettes
Professionals know that the best vaping experience is one that fits individual needs. That’s why many prefer to mix their own shortfill e-liquids with nicotine boosters, whether in the shop, at home, or on the go.
The Kit Professionals Use
Mixing nicotine shots like a pro doesn’t mean investing in lab equipment, but having the right kit certainly helps. Here’s what most experienced users have on hand:
- Shortfill bottle (50ml or 100ml)
- Nicotine shot (10ml, 18mg or 20mg)
- Vape kit suited to your mix (Mouth-to-Lung or Sub-Ohm)
- Gloves (optional but smart for cleanliness)
- Syringes or bottle nibs for precise measurement
- A clean surface and tissues for spills
Professional mixers often know their ratios by heart and mix in seconds—but even beginners can get it right with the proper tools and a bit of focus.
Mixing Like a Pro: Step-by-Step Process
So how do vape pros mix nicotine shots into shortfill bottles without messing it up? It’s easier than it sounds. Here’s how it’s done:
Step 1: Decide Your Nicotine Strength
Most shortfill bottles are sold as 50ml in a 60ml bottle, or 100ml in a 120ml bottle, so there’s space to add nic shots.
To mix to 3mg nicotine strength:
- Add 1x 10ml 18mg nic shot to a 50ml shortfill
- Add 2x 10ml 18mg nic shots to a 100ml shortfill
For a 6mg strength (if your device can handle it), you’ll need 2x 10ml shots in a 50ml shortfill—but this will dilute the flavour slightly.
Step 2: Choose the Right Type of Nic Shot
- Freebase nic shots give a sharper hit, ideal for Sub-Ohm vaping
- Nic salt shots are better for Mouth-to-Lung devices and ex-smokers who want a smoother feel with quicker nicotine delivery
A lot of ex-smokers prefer nic salt shots when first switching, because they more closely mimic the nicotine satisfaction of cigarettes. You can read more about that in this blog on why nicotine shots are popular among ex-smokers.
Step 3: Add Your Nic Shot
Remove the nib from the shortfill bottle and pour in your nicotine shot. You can also use a syringe for precision if you're trying to mix a specific strength or create a multi-nic blend.
Make sure everything is clean and sealed properly to avoid contamination or leaks.
Step 4: Shake Vigorously
Once your nicotine booster is added, shake the bottle thoroughly. Professionals usually recommend shaking for 1–2 minutes to ensure full distribution. You’ll know it’s ready when the bubbles settle and the liquid looks smooth and even.
Step 5: Steep (Optional)
Some vapers like to steep their mix—especially for dessert or tobacco flavours. This means letting the mix sit for a few days to blend properly. Fruity or minty flavours don’t usually need this, but heavier flavour profiles can benefit from it.
Real-World Tips From Vape Enthusiasts
If you hang around vape communities long enough, you’ll notice a few unwritten rules and tips for getting the best out of your nic shot mixes. Here’s what seasoned vapers often recommend:
- Always label your bottles if you’re mixing multiple strengths or flavours.
- Use dark, cool storage to keep nicotine fresh (it degrades in heat and light).
- Don’t overfill—leave space for air so the liquid can mix properly.
- Check for compatibility between VG/PG ratios and your device.
Professionals treat their vape kits like a barista treats their espresso machine. Every detail matters, and once you get the hang of it, it becomes second nature.
The Role of Vape Kits in Custom Nicotine Mixing
Mixing nic shots is only one half of the equation. You need a vape kit that suits the style and strength of your mix. A high-powered Sub-Ohm kit, for example, is perfect for low-strength (3mg) freebase nicotine mixes. On the other hand, a sleek pod system or MTL device is better for nic salt blends with higher nicotine content.

Why Mixing Nicotine Shots Is for Everyone
Don’t be put off by the “professional” label. Mixing nic shots is not just for vape geeks or shop staff. It’s for anyone who wants a better experience—especially ex-smokers who need control, students on a budget, or professionals who want a discreet and satisfying vape setup.
Here’s why custom mixing nicotine shots is a good fit for all types of users:
For Ex-Smokers
- Customise nicotine strength to match cravings
- Gradually reduce intake over time
- Use nic salt shots for a smooth transition
For Casual Vapers
- Save money by buying shortfills and mixing at home
- Try different strengths with minimal effort
For Advanced Users
- Perfect your preferred throat hit
- Create blends with layered nicotine delivery
- Experiment with PG/VG ratios and device output
Mixing Nicotine Shots: A Smarter Alternative to Buying Pre-Mixed E-Liquids
The vaping market is flooded with pre-mixed options, but more and more people are turning to DIY mixing with nic shots because it simply makes more sense.
- More flexibility
- Greater value for money
- Better understanding of what you’re vaping
It’s also a great step for those using vaping as part of a harm reduction strategy. You’re not locked into fixed strengths. You get to control your intake on your own terms.
The Evolution of the Nicotine Shot Culture
Back in the day, you just picked a flavour and vaped. Now, thanks to TPD regulations and a more educated vaping community, we’re seeing the rise of a full-on DIY culture. Vape shops now offer nic shot calculators, nicotine salt options, and even workshops to teach you how to mix like a boss.
And while the word “professional” might sound intimidating, this culture is really about empowerment. It’s about giving you the tools, knowledge, and freedom to vape your way.
You Don’t Need to Be a Pro to Mix Like One
At the end of the day, mixing nicotine shots isn’t rocket science. It’s just smart vaping. With a bit of knowledge, the right equipment, and a touch of curiosity, anyone can do it—and do it well. Whether you’re looking to quit smoking, save money, or just fine-tune your vape experience, nicotine boosters are your ticket to custom vaping freedom.
So, next time you grab a shortfill e-liquid, don’t just vape it—make it yours.
