“Strongest CBD e-liquid” can mean different things depending on what you prioritise: total milligrams in the bottle, milligrams per millilitre after mixing, or the overall intensity you experience at the coil.
This guide walks through Canavape’s highest-strength options, starting with customisable additive shots, then into popular 50ml flavours and practical mix examples, and finally a quick comparison with 80%+ CBD vape cartridges.
You’ll find clear mg/mL maths, device and mixing tips, and direct product links to help you choose your perfect high-strength setup.
If you want the most concentrated booster in the smallest volume, look at Your Blend 5000mg additive (10ml) or, if you prefer fuller-spectrum profiles and flexible strength, choose from our high-strength additive range.
And if you want high potency with flavour, combine a 50ml Canavape e-liquid with an additive to dial in your exact mg/mL.
We also include a quick note on when our 80%+ cartridges make sense versus e-liquid.
For a neutral UK overview of vaping devices and use (note: CBD e-liquids are nicotine-free), see the NHS guide to using e-cigarettes.
This covers device fundamentals that also influence how strong a vape can feel at the mouthpiece.
For maximum flexibility in the smallest bottle, Your Blend packs 5000mg in 10ml.
It’s designed as a booster to add into compatible e-liquids (generally 50/50-style bases) and lets you push total milligrams per millilitre to very high levels with precision.

Prefer to tailor strength while also choosing the cannabinoid profile you like?
Pick from three additive families below and blend into a compatible 50/50-style e-liquid to achieve your target mg/mL:
| Additive | Why choose it | Pairs well with |
|---|---|---|
| Your Blend 5000mg | Maximum mg/mL headroom in 60ml mixes | Any 50ml flavour you already love (must be min 50% PG ratio) |
| Full Spectrum | Broader plant profile with terpene character | Terpene e-liquids (e.g., Purple Kush) |
| Broad Spectrum | Multi-cannabinoid without THC being the goal | Fruit & dessert profiles |
| Pure CBD | Predictable, neutral strength boost | Any flavour when you don’t want to change taste |
These three 50ml bottles are popular choices to pair with additives. They deliver flavour and terpene character out of the box and are easy to boost to your preferred strength.
Classic terpene-led profile in a 50ml format with 1800mg total. Rich, rounded notes make it a strong base for high-strength blends. Product page: Purple Kush Terpene CBD E-liquid 1800mg.
Cool, refreshing fruit profile with 1250mg in 50ml. Ideal if you like a crisp, clean flavour that still carries high-strength booster shots well. Product page: Watermelon Ice CBD E-liquid 1250mg.
A tropical broad spectrum blend in 50ml with 1250mg total. Layered fruit makes it a favourite mixer for strong yet smooth all-day setups. Product page: Pineapple Peach & Mango CBD E-liquid 1250mg.
When you boost a 50ml bottle with a 10ml additive, you end up with 60ml total. The total milligrams divided by 60 gives your mg/mL.
Here are real examples using the bottles above and two popular additive strengths (1200mg and 2400mg), plus Your Blend 5000mg.
| Base e-liquid | Additive | Total mg | Total volume | Approx mg/mL |
|---|---|---|---|---|
| Watermelon Ice 1250mg (50ml) | Pure CBD 1200mg (10ml) | 2450mg | 60ml | ≈ 40.83 |
| Watermelon Ice 1250mg (50ml) | Full or Broad 2400mg (10ml) | 3650mg | 60ml | ≈ 60.83 |
| Pineapple Peach & Mango 1250mg (50ml) | Full or Broad 2400mg (10ml) | 3650mg | 60ml | ≈ 60.83 |
| Purple Kush 1800mg (50ml) | Pure CBD 1200mg (10ml) | 3000mg | 60ml | ≈ 50.00 |
| Purple Kush 1800mg (50ml) | Full or Broad 2400mg (10ml) | 4200mg | 60ml | ≈ 70.00 |
| Any 50ml (e.g., 1250mg) | Your Blend 5000mg (10ml) | 6250mg | 60ml | ≈ 104.17 |
| Any 50ml (e.g., 1800mg) | Your Blend 5000mg (10ml) | 6800mg | 60ml | ≈ 113.33 |
These numbers are why additive shots are the easiest route to a truly strong CBD e-liquid.
They let you keep your favourite flavour while pushing mg/mL to your preferred level with predictable maths.
| Coil / Power | Why it helps at high mg/mL | Notes |
|---|---|---|
| 0.8-1.2Ω, ~10-16W | Keeps temperatures sensible; flavour stays smooth | MTL pod devices excel here |
| Lightly restricted airflow | Concentrates aroma, reduces harshness | Avoid hot, long pulls |
| Short sips, 30-60s between | Lets wicks re-saturate | Protects coil life |
Cartridges are a different format to e-liquids: they’re pre-filled for convenience and designed to run on a low-voltage 510 battery.
If you want ultra-simple potency with tuned flavour and no mixing, they’re a great alternative to high-strength e-liquids.
Choose cartridges if you want no-fuss strength with consistent performance. Choose e-liquids + additives if you want to control flavour family, mg/mL, and bottle value, and you’re happy to refill a pod.
| Goal | Best pick | Why |
|---|---|---|
| Highest mg/mL in a mix | Your Blend 5000mg + a 50ml bottle | Pushes 60ml blends over 100 mg/mL depending on base |
| High-strength with fuller profile | Full Spectrum Additive + 50ml bottle | Flexible strength with a broader plant profile |
| Strong and straightforward | Pure CBD Additive + 50ml bottle | Clean CBD boost and predictable mixing |
| Potent with zero mixing | 80%+ cartridges | Ready-to-vape strength; just pair with a 510 pen |
Is higher mg/mL always better? Not necessarily. There’s a personal sweet spot where flavour, smoothness and overall experience balance out.
Use the tables above as a guide and start lower before stepping up.
Can I boost any e-liquid? Additives are intended for compatible bases (typically 50/50-style or a PG ratio of 50 percent or more).
Check your bottle’s label and keep ratios sensible for wicking and coil health.
When should I pick a cartridge instead? If you want the simplest route to strong performance with zero mixing, cartridges are ideal.
If you want flavour freedom, bottle value, and granular mg/mL control, e-liquid plus additive wins.
Choose your booster, pick your flavour, and set your strength.
Start with Your Blend 5000mg for maximum headroom, explore Full Spectrum, Broad Spectrum or Pure CBD for tailored builds, then pair with Purple Kush 1800mg, Watermelon Ice 1250mg or Pineapple Peach and Mango 1250mg.
Prefer pre-filled? Check out Blue Zkittlez, Orange Creamsicle and the Reserve Permanent Marker cartridge.
