What Is CBD Vape Juice?
CBD vape juice (also called CBD e-liquid) is a liquid designed specifically for vaporisation using a vape device.
Unlike regular CBD oil (which is taken under the tongue), vape juice is formulated with inhalation-safe ingredients that can be heated and turned into vapour.
What it contains:
- CBD extract → isolate, broad-spectrum, or full-spectrum
- Propylene Glycol (PG) → carries flavour and CBD
- Vegetable Glycerin (VG) → produces vapour clouds
- Optional flavourings or terpenes
These ingredients are combined to create a balanced liquid that:
- vaporises efficiently
- delivers CBD quickly into the bloodstream
- provides flavour and throat sensation
Important distinction:
Not all CBD oil is vape-safe. Only use products specifically designed for vaping.
Why Make Your Own CBD Vape Juice?
Making your own CBD vape juice gives you full control over what you inhale.
Control over strength
You decide exactly how much CBD goes into your mix. This allows:
- precise dosing
- easier adjustment over time
THC control (UK compliance)
By choosing the type of extract:
- CBD isolate → 0% THC
- Broad-spectrum → THC-free
- Full-spectrum → trace THC
This helps you stay within UK legal limits.
Custom flavour profiles
You can create:
- fruit blends
- mint or cooling effects
- terpene-based cannabis flavours
Ingredient transparency
You know exactly what’s inside your vape juice:
- no unknown additives
- no unnecessary fillers
Cost efficiency
DIY vape juice is often cheaper long-term compared to pre-made products.
Ingredients You Need to Make CBD Vape Juice
To make CBD vape juice safely, you need high-quality, vape-safe ingredients.
1. CBD Extract (Core Ingredient)
You can choose:
- CBD Isolate → pure CBD, easiest to mix
- Broad-spectrum → no THC, more plant compounds
- Full-spectrum → contains trace THC
CBD isolate is the most beginner-friendly option.
2. Propylene Glycol (PG)
- Thin liquid
- Helps dissolve CBD
- Provides “throat hit” sensation
CBD dissolves well in PG, making it essential for mixing.
3. Vegetable Glycerin (VG)
- Thick liquid
- Produces vapour clouds
- Smooths the inhale
4. Flavourings or Terpenes (Optional)
- Adds taste and aroma
- Must be safe for inhalation
- Avoid oil-based flavourings
Recommended PG/VG ratios:
- 50/50 → balanced
- 60/40 (PG/VG) → stronger flavour, thinner liquid
- High VG → smoother but harder to dissolve CBD
Equipment Needed
Using the right tools ensures accuracy and safety.
Essential tools:
- Digital scale (precise measurement)
- Syringes or pipettes
- Glass mixing container
- Stirring tool
- Empty vape bottles
- Gloves (for hygiene)
Optional:
- Magnetic stirrer (for better mixing)
- Funnel (to avoid spills)
Accuracy matters, incorrect ratios can affect:
- CBD strength
- vapour quality
- device performance
Step-by-Step Guide: How to Make CBD Vape Juice
Here is a clear, beginner-friendly process.
Step 1: Measure your CBD
- Weigh your CBD isolate (e.g. 500mg)
- Adjust based on desired strength
Example: 500mg CBD in 30ml = moderate strength
Step 2: Add Propylene Glycol (PG)
- Add PG to your container
- Mix CBD into PG first
Important: CBD dissolves in PG, not VG.
- Stir until fully dissolved
Step 3: Add Vegetable Glycerin (VG)
- Add VG gradually
- Mix thoroughly
This creates the final vape consistency
Step 4: Add Flavour (Optional)
- Add a few drops of flavouring
- Mix slowly
Start low, you can always add more
Step 5: Final Mix
- Stir or shake thoroughly
- Ensure no separation
Step 6: Steep (Optional but recommended)
- Store in a cool, dark place
- Wait 24–48 hours (or longer)
This improves flavour and consistency.
Step 7: Bottle and label
- Transfer into vape bottles
Label:
- CBD strength
- date
- flavour
How to Calculate CBD Strength
Understanding strength helps you dose correctly.
Simple formula:
Total CBD (mg) ÷ Total liquid (ml) = mg/ml
Example:
- 500mg CBD ÷ 30ml = ~16.6 mg/ml
Higher mg/ml = stronger vape juice
Common Mistakes to Avoid
Avoid these issues to ensure safety and quality:
Using regular CBD oil
Not designed for vaping → can damage devices and lungs
Wrong PG/VG ratio
Too much VG:
- poor CBD dissolution
- weak delivery
Overflavouring
Too much flavour:
- harsh inhale
- unpleasant taste
Poor mixing
CBD may separate → always shake before use
Low-quality ingredients
Unverified CBD may contain:
- contaminants
- incorrect potency
Is It Legal to Make CBD Vape Juice in the UK?
Yes, but with conditions.
CBD is legal in the UK if:
- THC content is within legal limits
- It is not marketed as a medicine
- Ingredients comply with safety standards
CBD products can be legally sold if they meet UK requirements and do not exceed THC limits.
Important:
- Selling DIY vape juice = regulated
- Personal use = generally allowed
