Navigating the World of E-liquids: A Comprehensive Guide

E-liquids, also known as vape juice or e-juice, are the essential ingredients that transform electronic cigarettes, or e-cigarettes, into flavorful vaporizers. These liquid solutions comprise a blend of propylene glycol (PG), vegetable glycerin (VG), flavourings, and, in most cases, nicotine. The choice of PG and VG ratio influences the vaping experience, affecting factors like vapour production and throat hit.

Unveiling the Composition of E-liquids

Propylene Glycol (PG)

Propylene glycol is a colourless, odourless, and hygroscopic liquid that serves as the base for most e-liquids. It contributes to the throat hit, the sensation felt in the back of the throat when inhaling vapour. PG also carries flavourings effectively, making it an essential component for achieving a flavorful vaping experience.

Vegetable Glycerin (VG)

Vegetable glycerin, a thick, colourless, and odourless liquid, acts as the other primary component in e-liquids. It produces thicker vapour clouds and enhances the sweetness of flavourings. VG is generally considered smoother than PG and may be preferred by those who find PG too harsh.


Flavourings are the key to the vast array of flavours available in the e-liquid market. These flavourings, food-grade additives, impart a wide range of tastes, from fruity and refreshing to dessert-inspired and tobacco-flavoured options.

Nicotine (Optional)

Nicotine, an addictive substance found in tobacco, is an optional ingredient in e-liquids. Its presence and concentration determine the nicotine strength of an e-liquid. Nicotine levels range from zero (nicotine-free) to high concentrations, catering to diverse preferences and smoking cessation goals.

Understanding Nicotine Strength

Nicotine strength is typically measured in milligrams per millilitre (mg/ml). The higher the nicotine concentration, the stronger the throat hit and the more potent the nicotine effect. Common nicotine strengths include:

  • 0mg/ml: Nicotine-free
  • 3mg/ml: Low-strength nicotine
  • 6mg/ml: Mid-strength nicotine
  • 12mg/ml: High-strength nicotine
  • 18mg/ml: Very high-strength nicotine

Exploring E-liquid Ratios: PG vs. VG

The ratio of PG to VG in an e-liquid significantly impacts the vaping experience. A higher PG ratio typically results in a stronger throat hit, while a higher VG ratio produces thicker clouds and a smoother vape. Common PG/VG ratios include:

  • 50/50: A balanced blend that provides a moderate throat hit and vapour production
  • 70/30: A higher PG ratio for a stronger throat hit and clearer flavour
  • 80/20: A higher VG ratio for thicker vapour clouds and smoother vape

Factors Influencing E-liquid Choice

Choosing the right e-liquid depends on personal preferences and vaping goals. Consider the following factors:

  • Throat Hit Preference: For a stronger throat hit, opt for a higher PG ratio. For a smoother vape, choose a higher VG ratio.
  • Flavor Profile: Explore the vast array of flavours available to find those that suit your taste.
  • Nicotine Strength: Select a nicotine strength that aligns with your needs, whether reducing nicotine intake or transitioning away from smoking.

Safely Enjoying E-liquids: Essential Considerations

  • Purchase E-liquids from Reputable Sources: Ensure e-liquids are sourced from reputable manufacturers that adhere to safety standards and use high-quality ingredients.
  • Store E-liquids Properly: Keep e-liquids out of reach of children and pets. Store in a cool, dark place to preserve flavour and quality.
  • Handle E-liquids with Care: Avoid direct contact with skin and eyes. In case of accidental contact, rinse thoroughly with water.
  • Follow Recommended Usage Guidelines: Adhere to the recommended usage guidelines provided by the e-liquid manufacturer.
  • Practise Responsible Vaping: Avoid excessive vaping and be mindful of the potential effects on others.

Conclusion: Navigating the World of E-liquids Responsibly

E-liquids offer a diverse range of flavours and nicotine strengths, catering to a variety of vaping preferences. Understanding the composition of e-liquids, exploring PG/VG ratios, and carefully considering nicotine strength are crucial steps in selecting the right e-liquid for your needs. Remember to prioritise safety, purchase from reputable sources, handle e-liquids with care, and practise responsible vaping habits
