How to Make Your Own CBD Vape Liquid: A DIY Guide

Ever wished you could create the perfect CBD vape juice? Maybe a little stronger, or with a specific flavour you can’t find anywhere? Good news: becoming the master of your own CBD e-liquid is way easier and more affordable than you might think.

This guide is here to walk you through the entire process, step by step. We promise, no complicated science, just a simple recipe for creating high-quality CBD vape juice at home.

Ingredients & Equipment: What You’ll Need to Get Started

Before you start mixing, having everything on hand makes the whole process smooth and simple.

Ingredients:

• CBD Booster Shots – the foundation of your e-liquid 
• Food-grade Propylene Glycol (PG) – emulsifies the CBD and carries flavour 
• Vegetable Glycerin (VG) – creates vapour clouds and adds smoothness

Essential Equipment: 

• Transparent measuring cups – precise measurements matter
• Glass beakers or sealable bottles – for mixing and storage 
• Blunt-tip syringes or pipettes – for accurate liquid transfers 
• Labels – to mark strength and date

Optional Add-ins: 

• Vape-safe flavouring concentrates (oil-free only) 
• Small funnel – makes pouring easier 
• Warm water bath – speeds up emulsification

Tip: Ensure that you source all of your ingredients from reputable retailers. None of the ingredients or required equipment pieces are illegal, and you will be able to find them without difficulty. We recommend acquiring all components from a reputable vaping retailer like MIST.

Step-by-Step DIY CBD Vape Juice

This recipe creates 100ml of CBD e-liquid. Scale up or down as needed, maintaining consistent ratios. This recipe presumes a 10ml 1200mg CBD Booster Shot is used.

Step 1: Measure Your CBD Booster

First up, measure out your CBD booster. To get a final strength of 500mg in your 100ml bottle, you’ll need to pour exactly 4.2ml of your 1200mg booster into your large mixing bottle.

Step 2: Add the PG and Get Mixing

Next, add about 40ml of your Propylene Glycol (PG) to the bottle. Put the cap on and shake it like you mean it. Don’t panic if it doesn’t mix perfectly right away—that’s totally normal. If it’s being a bit stubborn, you can give it some encouragement by placing the sealed bottle in a bowl of warm (not boiling!) water for 5-10 minutes. Give it a shake every now and then.

Step 3: Time for Flavour (Optional)

If you want to have flavour, now’s the time. A good starting point for a 100ml batch is between 5ml and 10ml of flavour concentrate (that’s 5-10% flavour). Just remember, most flavourings are PG-based, so this will count towards the PG side of your final PG/VG ratio.

Step 4: Top it Up with VG

Now for the clouds! Grab your Vegetable Glycerin (VG) and carefully add it to the mix until your total liquid reaches the 100ml mark on your bottle. A clean syringe can help you be precise here.

Step 5: The Final Shake!

Cap the bottle tightly and give it one last, vigorous shake for a good minute or two. You want everything to be perfectly blended, with no streaks or separation.

Step 6: Steep for a Better Taste

This last step is all about patience. Store your freshly made e-liquid in a cool, dark place (a drawer is perfect) for at least 24-48 hours. This “steeping” process allows the flavours to fully develop and results in a much better taste.

How to Calculate Your CBD E-Liquid Strength

With this recipe, the maths is super simple. You just need to know the strength of your booster shot.

The Formula: Total milligrams (mg) of CBD booster ÷ total millilitres (mL) of liquid = strength in mg/mL

Example Calculation: 500mg of CBD from booster shots mixed into 100mL of liquid gives you 5mg/mL strength. Each millilitre contains 5mg of CBD.

Our Advice: Start Low, Go Slow! New to DIY e-liquid? Begin with a lower concentration like 25mg/mL (250mg in 10mL). You can always make stronger batches once you know what works for you. Most people find 25-50mg/mL a good starting range.

Remember to account for any flavouring additions when calculating total volume. Those extra drops add up, especially in small batches.

Your Safety Checklist When Making CBD E-liquid at Home

Making your own juice is fun, but safety is everything. These rules are non-negotiable.

• Use Boosters, Not Oils: Never, ever use CBD oil tinctures (the kind you take orally) in your mix. They contain oils that are dangerous to inhale. Stick to proper CBD Booster Shots made for vaping.
• Work in a Clean Space: Sterilise all equipment with isopropyl alcohol and let it dry completely. Work on a clean, stable surface away from pets and children.
• Label Your Bottles: Mark each bottle with the date made, CBD strength in mg/mL, flavour used, and PG/VG ratio. This prevents mix-ups and helps track what works best for future projects!
• Store it Safely: Keep your finished juice in child-proof bottles, away from sunlight and heat. CBD e-liquid typically stays good for 1-2 years when stored properly.
• Do a Test Run: Before you fill your main tank, put a small amount in your device and test it on a low power setting.
