PG vs VG Ratios and Nicotine Levels Explained

What is E-Liquid? PG vs VG Ratios and Nicotine Levels Explained

For anyone stepping into the world of vaping, one of the first questions that comes up is: what exactly is e-liquid? Often called vape juice, e-liquid is the substance heated in your vape device to create vapor. It comes in countless flavors, strengths, and formulas, but at its core, e-liquid is a blend of a few key ingredients—primarily propylene glycol (PG), vegetable glycerin (VG), flavorings, and nicotine. Understanding how PG/VG ratios and nicotine levels work can help you choose the right e-liquid for your preferences and needs.

What is E-Liquid Made Of?

Most e-liquids contain four main components:

  • Propylene Glycol (PG): A thin, flavor-carrying base ingredient.
  • Vegetable Glycerin (VG): A thicker, sweeter base that produces vapor.
  • Flavorings: Food-grade ingredients that provide everything from fruity blends to dessert-inspired tastes.
  • Nicotine (optional): The stimulant found in tobacco, offered in different strengths or omitted entirely for zero-nicotine options.

PG vs VG Ratios: What’s the Difference?

The PG/VG ratio in e-liquid plays a huge role in how your vape feels and tastes.

PG (Propylene Glycol):

  • Provides a stronger throat hit, similar to traditional cigarettes.
  • Carries flavor more effectively, making it popular with flavor chasers.
  • Thinner consistency, which works well in smaller vape pens and pod systems.

VG (Vegetable Glycerin):

  • Creates thicker, denser clouds of vapor—great for “cloud chasers.”
  • Has a naturally sweeter taste, which can enhance dessert and fruit flavors.
  • Thicker consistency, better suited for more powerful sub-ohm devices.

Common ratios include:

  • 50/50 PG/VG: A balanced option with good flavor and decent vapor production, ideal for beginners.
  • 70 VG / 30 PG: Cloud-focused with a smoother inhale, perfect for sub-ohm vapers.
  • High PG blends: Sharper throat hit and stronger flavor delivery, favored by those switching from smoking.

Nicotine Levels in E-Liquid

Another important factor is nicotine strength, which can vary widely. Levels are usually measured in milligrams per milliliter (mg/ml).

  • 0mg: No nicotine—perfect for flavor enjoyment without the buzz.
  • 3mg to 6mg: Low nicotine, often used with sub-ohm devices where large vapor clouds deliver plenty of satisfaction.
  • 12mg to 18mg: Medium to high levels, best for mouth-to-lung (MTL) devices that mimic the feel of smoking.
  • Nicotine salts: A smoother form of nicotine available in higher strengths (20mg to 50mg), commonly used in pod systems for a strong but less harsh hit.

Choosing the Right E-Liquid for You

When selecting e-liquid, ask yourself:

  • Do you want stronger flavor or bigger clouds?
  • Are you looking for a cigarette-like throat hit or a smooth inhale?
  • How much nicotine do you need to satisfy cravings?

Experimenting with different PG/VG ratios and nicotine levels can help you find your perfect vape experience.

E-liquid may seem complicated at first, but once you understand the basics of PG vs VG ratios and nicotine levels, it becomes much easier to find what works best for you. Whether you prefer thick clouds, bold flavors, or a satisfying throat hit, the right balance is out there—it’s all about tailoring your vape juice to your style.
