Is It Safe to Mix Two Different E-Juices? Tips for Flavor & Safety
You’ve got one e-juice that’s almost perfect, and another that’s good but missing something.
So the big question hits, can you mix two different e-juices safely, or are you asking for trouble?
Good news, mixing e-juices can be safe.
But only if you do it right.
Let’s break down what’s safe, what’s risky, and how to mix flavours without ruining your vape (or your coils).
Can You Mix Two Different E-Juices?
Yes, adult vapers commonly mix e-juices to customize flavour, sweetness, or throat hit. But safety depends on what you’re mixing and how.
In general, mixing is safer when:
-
-
-
Both e-juices are from reputable brands
-
Nicotine strengths are compatible
-
PG/VG ratios are similar
-
You’re using clean equipment
-
-
If you’re unsure about device compatibility, browsing ready-to-use disposable vapes can be a simpler alternative to avoid mixing altogether.
Flavor Mixing, What Works (and What Doesn’t)
Some flavour combos work beautifully. Others, not so much.
Flavours that usually mix well,
-
-
-
Fruit + fruit (e.g., mango + berry)
-
Mint or menthol + fruit
-
Dessert + vanilla or cream
-
-
Flavours that often clash:
-
-
-
Tobacco + sweet desserts
-
Strong menthol + bakery flavours
-
Complex multi-flavour blends mixed together
-
-
Tip: Start small. Mix a few drops first instead of committing a whole bottle.
Nicotine Levels: Don’t Overdo It
One of the biggest mistakes people make when mixing e-juices is accidentally increasing nicotine strength.
Example:
Mixing two 20 mg/mL liquids doesn’t double the nicotine, but mixing different strengths can create an unexpected result.
Health Canada regulates nicotine limits in vaping products sold in Canada, capping them at 20 mg/mL for consumer safety.
Always calculate your final strength, especially if you’re sensitive to nicotine.
PG/VG Ratios Matter More Than You Think
E-juices are made of PG (propylene glycol) and VG (vegetable glycerin), and mixing very different ratios can affect:
-
-
-
Vapour production
-
Flavour intensity
-
Coil lifespan
-
Wicking performance
-
-
If your device struggles after mixing, it may not be the flavour, it could be the ratio.
This is one reason many vapers prefer pre-balanced disposable vapes, where everything is already optimized.
Is It Safe to Mix Brands?
Usually yes, if both brands are compliant and reputable.
Avoid mixing:
-
-
-
Unknown or unlabelled e-juices
-
Old or expired liquids
-
Products stored improperly
-
-
Stick to brands that clearly list ingredients and meet Canadian standards.
Cleanliness = Safety
Never mix directly inside a dirty tank or pod.
Always:
-
-
-
Clean your tank before mixing
-
Use a separate bottle or container
-
Label your mix
-
-
Mixing in an old tank can create weird flavours, or worse, burnt hits.
When You Should NOT Mix E-Juices
Skip mixing if:
-
-
-
You’re new to vaping
-
You’re using salt nicotine without understanding ratios
-
Your device is sensitive to viscosity changes
-
You want consistency every time
-
-
In those cases, sticking to pre-made flavour options is the safer move.
Mix Smart or Keep It Simple
So, is it safe to mix two different e-juices?
✔️ Yes, if you’re mindful of flavour balance, nicotine strength, and device compatibility
❌ No, if you’re guessing, rushing, or mixing random products
If you love experimenting, take it slow and mix responsibly.
If you prefer zero guesswork, ready-to-use options might be the better fit.
Either way, knowing the rules keeps your vaping experience smooth, safe, and enjoyable.
