For adult smokers (19+) who use vape products, understanding what’s inside an e-liquid can make the experience more predictable, more comfortable, and more enjoyable. While formulas vary across brands and devices, most e-liquids share three essential components: PG, VG, and nicotine. Some may also include flavourings, depending on the region and regulations.
This guide breaks down what each ingredient does — in a clear, neutral, science-based way — so adult users can make informed choices.
🟩 1. What Is PG (Propylene Glycol)?
PG is a thin, clear, odorless liquid commonly used in food, pharmaceuticals, and cosmetics.
What PG does in e-liquid:
-
Carries flavour effectively
-
Produces a stronger throat hit
-
Creates thinner vapor
-
Wicks quickly in most coils
Common observations from adult users:
-
Feels “sharper” on the throat
-
May cause dryness for some (PG is hygroscopic)
-
Works well in higher-resistance pod coils
Because PG is thinner, it flows easily through cotton wicks — making it ideal for low-power pod systems.
🟦 2. What Is VG (Vegetable Glycerin)?
VG is a thicker, sweeter, plant-based liquid used in foods, syrups, skincare, and more.
What VG does in e-liquid:
-
Produces dense, smooth vapor
-
Creates a softer throat hit
-
Adds slight sweetness
-
Helps vapor feel fuller and more “cloudy”
Common observations from adult vapers:
-
Ultra-smooth inhale
-
Better for those sensitive to throat hit
-
Thick VG can struggle in cold weather or smaller coils
VG is popular among adult users who prefer a gentler, smoother vape.
🟧 3. How PG/VG Ratios Affect the Experience
Most e-liquids fall into common ratio categories:
Higher-PG blends (e.g., 50/50 PG/VG or 60/40 PG/VG):
-
Stronger throat hit
-
Sharper flavour
-
Thinner liquid
-
Great for pod-style vapes
Higher-VG blends (e.g., 70/30 VG/PG or Max VG):
-
Dense, smooth vapor
-
Softer throat sensation
-
Slightly sweeter taste
-
Works best in higher-power coils or open airflow systems
In Canada:
Many sealed pods use balanced ratios like 50/50 or 55/45, ideal for adult smokers transitioning from cigarettes.
🟥 4. What About Nicotine? Freebase vs Nicotine Salt
Nicotine is optional — some adult vapers choose 0 mg — but for smokers transitioning, it affects smoothness and satisfaction.
Freebase Nicotine
-
Stronger throat hit
-
Sharper inhale
-
Used in higher-power devices
-
Common in open-tank systems
Adult smokers who prefer a “traditional cigarette-like bite” may notice this more.
Nicotine Salt (Nic Salts)
-
Much smoother
-
Designed for pod systems
-
Stable and consistent
-
Favoured in modern sealed pods and disposables
Nicotine salts allow higher strengths (up to Canada’s 20 mg cap) while staying smooth.
🟫 5. Flavourings (Depending on Local Regulations)
Flavourings are food-grade ingredients used in countless products like beverages, baking, and confectionery.
They influence:
-
aroma
-
sweetness
-
overall vape feel
Important:
Regulations vary by province in Canada. Some regions restrict flavours to tobacco, mint, or specific categories. Always check local rules.
🟩 6. Why Understanding Ingredients Matters (Adult Perspective)
Knowing what’s in an e-liquid helps adult smokers:
-
choose smoother or stronger throat sensations
-
avoid blends that feel too harsh
-
select pods that work better in cold weather
-
understand why vapor feels thin or thick
-
identify why some liquids dry the mouth more
Each ingredient plays a clear functional role — no mystery, no complexity.
🟦 Final Thoughts
E-liquids are built around a simple base: PG for throat hit and flavour, VG for smooth vapor, and nicotine for optional satisfaction. Small changes in ratio or nicotine type can dramatically affect how the vape feels.
For adult smokers (19+), understanding these components makes it easier to select products that match personal comfort and preference.
