If you are shopping for vape juice in Canada, you will quickly see two letters everywhere, PG and VG. At first, it can look technical. However, it is actually one of the simplest choices you can make, and it affects comfort right away. The ratio changes how strong the throat feel is, how thick the liquid is, how much vapour you get, and even how likely you are to deal with leaking or dry hits.

This guide keeps things easy to follow. You will learn what PG and VG do, how to pick a ratio based on your device and your preferences, and how to troubleshoot common problems. We will also keep the focus on MR FOG only.

Before we start, here are two Canada reminders.

In Canada, it is illegal to sell or provide vaping products to anyone under 18, and some provinces set the age higher.
Canada also limits nicotine concentration in vaping products sold legally to a maximum of 20 mg per mL.

Now let us get into the basics.

What PG and VG mean in plain English

PG stands for propylene glycol. VG stands for vegetable glycerin. They are both common ingredients used to carry flavour and nicotine in vape liquids.

You do not need to memorize chemistry. Instead, remember how each one behaves.

PG is usually about flavour and throat feel

PG is thinner and it carries flavour very well. It also tends to create more noticeable throat sensation, especially when nicotine is present. Because it is thinner, it wicks easily in many devices, which can feel consistent for shorter puffs.

VG is usually about smoothness and vapour

VG is thicker and it is known for producing denser vapour. It often feels smoother on the throat, although the exact feel depends on nicotine level and how warm the vapour is. Because VG is thicker, it can be harder for some coils to absorb quickly, especially if the device is small or the power is low.

So, the ratio is basically a comfort and performance dial.

Why the ratio matters more than most beginners think

Many new users focus only on nicotine strength or flavour names. However, the PG and VG ratio can change the entire experience even when everything else stays the same.

A higher PG mix often feels sharper and more defined. At the same time, it can be a bit drier for some people. Meanwhile, a higher VG mix often feels smoother and more cloud heavy, but it may need a device that can handle thicker liquid.

That is why the question PG vs VG is not just about clouds. It is also about how your device feeds liquid to the coil and how the vapour feels when you inhale.

PG VG throat hit and comfort

Some people want a stronger throat feel because it feels more satisfying. Others prefer smoothness.

If you are searching for PG VG throat hit, the simple rule is this.

More PG usually means more throat sensation. More VG usually means a softer feel.

Still, nicotine strength and puff style matter too. In Canada, the legal cap is 20 mg per mL, so many users tune comfort by choosing a ratio that matches their inhale style rather than trying to increase nicotine beyond the limit.

If your throat feels irritated, you can try one or more of these changes.

Choose a slightly higher VG ratio
Take shorter puffs and slow down
Lower nicotine within the legal options
Reduce vapour warmth if your device allows it

On the other hand, if the vapour feels too soft and you want a clearer throat feel, a little more PG can help.

Clouds and flavour balance

PG helps flavour feel crisp and bright. VG helps vapour feel thick and smooth. Therefore, many people try to find a middle ground.

If you want bigger clouds, more VG usually helps. If you want strong flavour clarity, more PG can help.

However, you should also match the ratio to your device. Otherwise, you might get problems like leaking, flooding, or dry hits. This brings us to the practical part.

PG VG for pod system

If you use a compact pod device, the wick and coil are typically designed for thinner liquid or balanced blends. That is why many beginners search PG VG for pod system when they notice inconsistent hits.

In simple terms, pod systems often perform best with balanced or moderately thin liquids, because the coil needs to stay saturated even with short puffs. If the liquid is too thick, the coil may not feed fast enough, especially when you take back to back puffs.

As a result, for many pod users, a balanced blend is the safest starting point.

50/50 vs 70/30 vape juice

A common beginner question is 50/50 vs 70/30 vape juice. This is a helpful comparison because it shows how different a ratio can feel.

50/50 usually means a balanced experience
It can feel more flavour forward and it tends to wick easily
It often works well for many beginners and many smaller devices

70/30 usually means more VG than PG
It can feel smoother and more cloud focused
It may require a device that can handle thicker liquid reliably

If you are not sure where to start, a balanced option is often easier. Then, you can move toward thicker or thinner blends based on how it feels.

Best PG VG ratio for beginners in Canada

There is no single best ratio for everyone. Still, there is a practical way to choose.

If you want a clear throat feel and crisp flavour, lean toward more PG.
If you want a smoother inhale and thicker vapour, lean toward more VG.
If you want fewer surprises while you learn, start balanced.

That is why many people search best PG VG ratio and end up choosing a middle ground first. After a week or two, your preferences become clearer, and then it is easier to fine tune.

Does VG cause leaking

People often ask does VG cause leaking. The honest answer is that VG alone is usually not the direct cause. In fact, thicker VG heavy liquid can sometimes reduce leaking because it moves more slowly.

However, leaking can still happen with any ratio if the setup is not matched properly.

Leaking is often caused by one or more of these.

A coil or pod that is worn out
Overfilling or getting liquid into the airflow path
Temperature changes that thin the liquid temporarily
Drawing too hard which pulls excess liquid into the coil area
Poor sealing or misaligned pod placement

So, if you have leaks, do not assume VG is the problem. Instead, use a simple checklist.

A simple leak and spitback checklist

If your device leaks or spits, try these steps in order.

1. Check the pod or tank seal
   Make sure everything is seated correctly and clean.

2. Do not overfill
   Leave a small air space so pressure stays stable.

3. Use gentler puffs
   Hard pulls can flood the coil.

4. Wipe condensation
   Moisture can collect in the airflow area and look like a leak.

5. Replace the coil or pod if it is old
   Old coils can lose efficiency and flood more easily.

If leaking keeps happening, consider adjusting the ratio. A slightly thicker blend can help some setups. Still, device condition and technique usually matter more.

Choosing a ratio for MR FOG devices

When you shop on MR FOG, the most important goal is consistency. A beginner friendly setup should deliver stable flavour and comfortable vapour without constant tuning.

If you are using a compact device, a balanced ratio is often a safe choice because it supports reliable wicking. If you prefer denser vapour and smoothness, you can move toward higher VG, as long as performance stays consistent for your device.

Some customers also look up MR FOG NOVA when comparing device options in the MR FOG lineup. If that is you, focus on matching your liquid thickness to the way the device wicks and the way you puff. Comfort and consistency should come first, especially in the first weeks.

Canada friendly tips for a better day to day experience

Because Canada limits nicotine concentration to 20 mg per mL, you may rely more on comfort choices like ratio and puff style to get the experience you want.
Here are a few simple habits that help.

Drink water
Vapour can feel drying, and hydration improves comfort

Take slower puffs
This reduces flooding and also reduces harshness

Let the coil soak after refilling
A few minutes helps prevent dry hits

Store liquid at room temperature
Cold can thicken VG, while heat can thin liquid and increase flooding risk

Also remember the age rules. In Canada it is illegal to sell or provide vaping products to anyone under 18, and some provinces set the age higher.
