PG and VG: The Ultimate 2026 E-Liquid Ratio Guide

You're probably here because you picked up a bottle or looked at a pod flavour online and saw 50/50, 70/30, or high VG, then realised nobody had explained what those numbers mean in plain English.

That confusion is normal. Most new adult vapers in Toronto don't start by asking about chemistry. They start by asking practical questions. Why does one vape feel sharper? Why does another make bigger clouds? Why does one liquid work well in a STLTH pod while another suits a Vaporesso kit better?

The short answer is pg and vg. Those two ingredients shape most of your day-to-day vaping experience. Once you understand them, e-liquid labels stop looking like code and start looking useful.

Your Guide to PG and VG in E-Liquid

A common first-time shopping moment goes like this. You're looking at nic salts, freebase bottles, or a new pod flavour, and every option seems to come with a ratio. One says 50/50. Another says 70VG/30PG. A disposable feels smooth, but a pod system feels more cigarette-like, and you're not sure why.

That ratio tells you how the liquid is built. PG stands for propylene glycol. VG stands for vegetable glycerin. They're the main carrier liquids in e-liquid, and they affect flavour, throat hit, vapour output, and how well a liquid works in different devices.

In Canada, Health Canada regulates e-liquids under the Tobacco and Vaping Products Act, enacted on August 17, 2018, and requires PG and VG to make up at least 95% of e-liquid solvents by volume, excluding nicotine, water, and flavours. A 2022 Health Canada compliance survey of 250 e-liquid samples from retailers across Ontario found 98% adherence to that ratio, according to this PG and VG regulatory overview.

That matters because it gives adult vapers a reliable starting point. When you buy compliant e-liquid in the GTA, PG and VG aren't mystery ingredients. They're the core base of the product.

Why most people get stuck on ratios

The labels look technical, but the decision is simpler than it seems:

• Choose more PG if you want clearer flavour, a firmer throat hit, and better performance in many pod-style devices.
• Choose more VG if you want a smoother inhale and thicker vapour.
• Choose a balanced ratio if you want an all-around experience.

If you want a broader beginner-friendly explanation of how vape liquid is put together, this guide on what e-juice is helps connect the ingredients to the overall product.

Practical rule: Don't start by chasing the “best” ratio. Start by matching the liquid to your device and the kind of inhale you actually enjoy.

What is Propylene Glycol (PG)

Propylene glycol, usually shortened to PG, is the thinner side of e-liquid. If you want a simple mental model, think of PG as the flavour carrier.

It moves easily through smaller coils and pods, and it delivers a more noticeable sensation on the inhale. That's why many adult smokers who switch to vaping tend to notice PG right away, even if they don't know the name yet. What they're really noticing is the sharper feel and clearer flavour delivery.

What PG does when you vape

PG affects the parts of vaping that people feel immediately.

• Flavour clarity
  PG tends to make flavours feel more defined. If you're using tobacco, mint, menthol, or fruit blends and want the taste to come through cleanly, PG helps with that.
• Throat hit
  This is the slight catch or grip in the throat when you inhale. Many former smokers prefer some throat hit because it feels more familiar than an ultra-soft inhale.
• Fast wicking in smaller devices
  Because PG is thinner, it usually travels through cotton and small coil openings more easily than thicker liquid does.

Why pod users often end up with more PG

Most mouth-to-lung devices, especially compact pods, work best when the liquid isn't too thick. A thinner liquid can soak into the coil more reliably, which helps prevent weak puffs or burnt-tasting hits.

That's why a lot of nic salt products for pod systems use balanced or PG-leaning ratios. If you've tried STLTH-compatible products, Flavour Beast nic salts, or similar compact-device liquids, you've already seen how common that setup is.

PG is often the ingredient behind the sentence, “This one feels more like a cigarette.”

Where new vapers get confused about PG

People sometimes assume more flavour always means a better vape. Not necessarily. More PG can mean stronger flavour delivery and more throat hit, but if your personal preference is a soft, airy inhale, that same liquid might feel too sharp.

PG also isn't a signal of quality by itself. It's just one half of the formula. A great PG-heavy liquid in the wrong device can feel harsh. A balanced liquid in the right pod can feel spot on.

A simple way to think about PG

Use this shortcut when reading labels:

If your setup is compact, low-powered, and designed for nic salts, PG is usually doing a lot of the heavy lifting.

What is Vegetable Glycerin (VG)

If PG is the flavour carrier, vegetable glycerin, or VG, is the cloud creator.

VG is much thicker than PG, and you can feel that difference in the vape. Liquids with more VG usually inhale more softly and produce a fuller, denser vapour. That's why high-VG e-liquid is commonly linked with larger devices, sub-ohm tanks, and direct-to-lung vaping.

Why VG feels different

VG changes the vape in two very obvious ways. First, it softens the inhale. Second, it creates more visible vapour.

That smoothness is one reason some adult vapers prefer high-VG freebase e-liquids in larger kits from brands such as Vaporesso, SMOK, or Uwell. Instead of focusing on a sharp throat hit, those setups usually aim for a fuller draw and a bigger cloud.

According to this Canadian guide to vape liquid ingredients, PG has a viscosity of approximately 0.042 Pa·s at 20°C, while VG is about 1.5 Pa·s. The same source notes that PG's lower boiling point is 188°C compared with VG's 290°C. In simple terms, PG is thinner and easier for small pods to wick, while VG is thicker and better known for dense vapour in sub-ohm setups.

What thickness means in real life

That viscosity point sounds technical, but the practical meaning is easy to understand.

• Thin liquid moves quickly into smaller coils.
• Thick liquid needs more room, more heat, and better wicking.
• If the device can't keep up, the vape can taste dry or burnt.

This is why someone can love a high-VG bottle in a larger mod, then hate that same liquid in a compact pod. The issue often isn't the flavour. It's the mismatch between liquid thickness and hardware.

If you want a deeper look at how this ingredient behaves in vape liquid, this article on vegetable glycerin in vape products is a helpful companion read.

A thick liquid isn't “too much” on its own. It's only too much for the wrong coil.

A useful way to picture VG

Think of VG as the heavier base in the mix. It brings body to the vapour. That body can make the inhale feel smoother, but it can also slightly soften flavour edges compared with a PG-forward blend.

For many adult vapers, that trade-off is worth it. If the goal is comfort, dense vapour, and a less sharp draw, VG is usually the ingredient making that happen.

Comparing PG vs VG Effects

By this point, the easiest way to understand pg and vg is to compare what they do side by side. Most e-liquid decisions come down to four things. Throat hit, flavour, clouds, and thickness.

PG vs VG At-a-Glance

Throat hit and smoothness

This is usually the first difference people notice. A higher-PG liquid often feels more direct on the inhale. A higher-VG liquid feels softer and rounder.

Neither one is automatically better. If you've recently switched from cigarettes and want that familiar sensation in the throat, PG-heavy or balanced blends often make more sense. If you dislike any sharpness at all, more VG usually feels more comfortable.

Flavour and vapour

People often assume flavour and clouds always rise together. They don't.

PG tends to present flavour with more edge and clarity. VG tends to create more visible vapour and a smoother mouthfeel. That means a liquid can taste crisp without producing a giant cloud, or it can produce a large cloud while tasting more rounded.

Quick takeaway: PG usually shapes how clearly you taste the liquid. VG usually shapes how fully you see and feel the vapour.

Coil behaviour and device fit

This part causes a lot of frustration for beginners because the symptoms can look random. Maybe one liquid works beautifully in a pod, while another spits, floods, or tastes burnt.

The cause is often simple. Thin liquid suits smaller, lower-power systems. Thick liquid usually suits larger, more powerful ones.

Here's a plain-language breakdown:

• Pod systems and MTL devices usually prefer thinner or balanced liquids because the wick openings are smaller.
• Sub-ohm tanks and DTL kits usually handle thicker liquids better because they use more power and larger wick channels.
• Disposable-style performance varies by design, but the same rule still helps. Match the liquid style to the way the device is built.

Which one should matter most to you

Ask yourself which of these sounds most like your goal:

1. “I want something that feels closer to smoking.”
   You'll probably prefer a balanced or more PG-forward ratio.
2. “I want a smoother inhale with more vapour.”
   You'll probably lean toward more VG.
3. “I use a simple pod and don't want dry hits.”
   Keep a close eye on thickness.
4. “I use a stronger kit and enjoy bigger pulls.”
   A higher-VG blend is often the better fit.

The ratio isn't just about preference. It's also about compatibility. Good e-liquid selection is really the overlap between what you like and what your device can handle.

Choosing the Right PG/VG Ratio for Your Vape

Ratios represent the shift from theory to practical shopping logic. You don't need to memorise every blend on the shelf. You just need to know which ratio usually fits your device style.

A balanced 50/50 liquid is often the easiest place to start for adult vapers using pod systems. It gives you a mix of flavour clarity, manageable vapour, and a throat hit that many recent switchers find familiar. That's why 50/50 nic salts are so common in compact devices and prefilled pod ecosystems.

A higher 70VG/30PG style usually makes more sense for stronger kits built for direct-to-lung use. Those devices are designed for thicker liquid and more vapour production.

What the Ontario data suggests

A 2021 Ontario Ministry of Health study covering 1,200 e-liquid samples from GTA vape shops found that 75% of 19+ vapers preferred 70VG/30PG for direct-to-lung devices, while 55% of ex-smokers favoured 50/50 for mouth-to-lung pod systems like STLTH. The same source says nicotine delivery efficiency peaked at 50PG/50VG, with a 92% absorption rate.

That lines up with what many adult vapers notice in practice. Pods and cigarette-style draws often feel best with balanced liquids. Larger mods and open airflow setups usually come alive with more VG.

A simple device-based guide

For pod systems and nic salts

If you use something in the lane of STLTH, Allo Sync, or another compact MTL-style device, start with a 50/50 ratio unless the manufacturer suggests otherwise.

Good fit categories often include:

• Nic salts for a firmer throat hit and efficient delivery
• Tobacco, mint, menthol, and fruit blends where flavour definition matters
• Brands such as Flavour Beast, Lemon Drop, Allo, and STLTH-style products that are often chosen for pod-friendly performance

These setups suit adult vapers who want a smaller draw, more discretion, and a feel that's closer to smoking.

For mods, tanks, and bigger airflow

If you use a Vaporesso, SMOK, Voopoo, or similar open-system kit designed for bigger pulls, a 70VG/30PG liquid often makes more sense.

That usually fits people who want:

• More vapour
• A smoother inhale
• Lower sharpness in the throat
• Better performance in sub-ohm hardware

Here's a visual walkthrough that can help if you're comparing ratios and device types:

What about disposables

Disposables can confuse people because you're not filling them yourself. Even so, the same ratio logic still helps explain why one disposable feels smooth and another feels punchier.

If you enjoy products from names like Lost Mary, Geek Bar, ELF Bar, or STLTH Eco, what you're really reacting to is still the same mix of throat hit, vapour feel, and device design. When you later move into refillable products, knowing your PG/VG preference makes that transition much easier.

If you liked a pod or disposable because it felt tight, clear, and satisfying, don't automatically jump to a high-VG bottle. Start closer to the experience you already know you enjoy.

PG Allergies Safety and E-Liquid Storage

Most adult vapers won't have a problem with PG or VG, but some people do notice that one type of liquid feels better than another. The key is to watch your own experience without jumping to conclusions.

If a liquid feels unusually scratchy, dries your throat, or just doesn't sit right, the simplest test is often to try a more VG-heavy option and see whether the inhale feels smoother. If your device is a pod system, though, don't swing too far into very thick liquid unless the hardware can handle it.

Sensitivity and device fit aren't the same thing

People often blame the ingredient when the underlying issue is compatibility. A thick liquid in a small pod can cause poor wicking. That can create a rough or unpleasant vape even if the user isn't sensitive to VG at all.

For GTA pod users, this guide discussing nic salt ratios in pod systems notes that high PG ratios such as 50/50 or 70/30 PG/VG enhance throat hit and flavour clarity in compliant nic salts. It also says Ontario data shows 62% of vapers prefer nic salts for quitting smoking, and that a 50PG/50VG selection can reduce dry hits by 40% in low-watt pods.

So before you decide an ingredient is the problem, check the setup first:

• Using a compact pod and getting dry hits? Try a thinner or balanced liquid.
• Using a bigger mod and finding the inhale too sharp? Try more VG.
• Getting discomfort across several liquids? Pause, simplify, and test one change at a time.

Don't troubleshoot three variables at once. Change the ratio, keep the device the same, and pay attention to how the vape feels over a few sessions.

Safe handling and storage habits

E-liquid lasts best when you store it carefully. Heat, direct light, and sloppy handling can dull flavour and make the overall experience less consistent.

A simple routine works well:

• Keep bottles sealed when you're not using them.
• Store them in a cool, dark place rather than on a sunny windowsill or in a hot car.
• Wipe drips off the bottle and device so residue doesn't build up.
• Keep products away from children and pets and follow the labelled warnings.
• Check your coil before blaming the liquid because an old coil can make even a good e-liquid taste wrong.

When to switch ratios

A ratio change makes sense if your current vape keeps missing the mark.

Try changing the blend if:

• the throat hit feels stronger than you want
• the vapour feels too thin
• the flavour seems too muted for your taste
• your pod struggles with the liquid you're using

Sometimes the fix is not a new device or a new brand. It's just a better-matched PG/VG ratio.

Finding Your Perfect E-Liquid at Wii Vape

The easiest way to remember pg and vg is this. PG leans toward flavour clarity, throat hit, and pod-friendly flow. VG leans toward smoothness, denser vapour, and larger-device performance.

That's why ratio labels matter more than many beginners realise. A 50/50 nic salt can feel excellent in a compact MTL setup. A 70VG/30PG freebase liquid can feel far better in a sub-ohm kit. If you mix those up, the problem often shows up as weak flavour, rough hits, or poor wicking.

For adult vapers in Toronto and the GTA, the practical next step is to shop by device type first, then flavour, then ratio. If you use a prefilled pod or a small refillable kit, start by browsing nic salts and pod-friendly blends. If you use a larger Vaporesso, SMOK, Uwell, or Voopoo device, look more closely at freebase and high-VG options. If you mostly use disposables and want to move into refillables, use your favourite disposable's inhale style as your clue.

The good news is that once you know your ratio preference, shopping gets much easier. You stop guessing. You start recognising what “balanced”, “smooth”, and “stronger throat hit” will feel like in your hand, in your coil, and on your inhale.

If you're ready to put that knowledge to work, browse Wii Vape for nic salts, freebase e-liquids, disposables, pods, coils, and starter kits from brands adult GTA vapers already know, with local support and same-day delivery options that make finding the right setup much easier.
