What Are the Ingredients in Vape Liquids?

Vape liquids, also known as e-liquids, are liquids used in electronic vaping devices to produce vapour. Understanding what these liquids contain can help people access clear, unbiased information about vaping.

This guide explains the common ingredients found in vape liquids, their purpose, and health and regulatory considerations in New Zealand. This content is purely informational and does not promote or encourage vaping.

What Is Vape Liquid?

Vape liquid, or e-liquid, is a specially formulated fluid that is heated by a vaping device to create an aerosol, commonly called vapour. This vapour is then inhaled by the user.

E-liquids usually contain a few core ingredients, although the exact formulation can vary depending on the product. Some vape liquids contain nicotine, while others are nicotine-free.

Main Ingredients in Vape Liquids

Propylene Glycol (PG)

Propylene glycol is a colourless, odourless liquid commonly used in food, pharmaceuticals, and cosmetics. In vape liquids, PG is used as a base ingredient.

  • Helps carry flavour effectively
  • Creates a throat hit similar to smoking
  • Has a thinner consistency than other base liquids

Vegetable Glycerine (VG)

Vegetable glycerine is a thicker, slightly sweet liquid made from plant oils. In vape liquids, VG helps produce vapour.

  • Creates denser vapour clouds
  • Provides a smoother inhalation experience
  • Balances the effect of propylene glycol

Most e-liquids use a mixture of PG and VG in different ratios.

Nicotine

Nicotine is an optional ingredient in vape liquids. It is a naturally occurring substance found in tobacco plants and is known to be addictive.

Nicotine commonly appears in two forms:

  • Freebase nicotine: A traditional form used in many vape products.
  • Nicotine salts: A modified form that may be absorbed more quickly and is often smoother to inhale.

Not all vape liquids contain nicotine. Some are labelled as nicotine-free.

Flavourings

Flavourings are added to create different tastes and aromas. These may range from tobacco-style flavours to fruit or dessert-like flavours.

Vape liquids often use food-grade flavourings, but the safety of inhaling flavourings is still being researched.

What Do Vape Liquid Ingredients Do?

  • Propylene glycol: Helps deliver flavour and creates throat sensation.
  • Vegetable glycerine: Produces vapour and smoothens inhalation.
  • Nicotine: Provides stimulant effects and may cause addiction.
  • Flavourings: Add taste and smell.

The combination of these ingredients affects vapour production, flavour strength, and throat feel.

Are Vape Liquid Ingredients Safe?

The safety of vape liquid ingredients depends on how they are used and a person’s health condition.

  • Some ingredients, such as PG and VG, are used in food and cosmetics.
  • Inhaling these substances may have different health effects from eating them.
  • The long-term health effects of vaping are still being studied.
  • Nicotine is addictive and may affect cardiovascular and nervous system health.

Health authorities generally advise that vaping is not risk-free and should not be started by non-smokers.

How Vape Liquid Ingredients Are Regulated in New Zealand

In New Zealand, vape products are regulated under the Smokefree Environments and Regulated Products Act.

  • Nicotine-containing products cannot be sold to people under 18.
  • Ingredient disclosure and labelling requirements apply.
  • Advertising and promotion are restricted.
  • Product safety and packaging standards must be followed.

Nicotine vs Nicotine-Free Vape Liquids

Nicotine-Containing Vape Liquids

  • Contain different strengths of nicotine
  • Carry a risk of addiction
  • Are often used by adult smokers as an alternative to cigarettes

Nicotine-Free Vape Liquids

  • Do not contain nicotine
  • Still contain PG, VG, and flavourings
  • May still present health risks from inhaling aerosolised substances

Health Factors and Risks

Vaping involves inhaling aerosolised substances into the lungs, which may pose health risks.

  • Addiction: Nicotine-containing products may cause dependence.
  • Respiratory effects: Vapour inhalation may irritate the airways.
  • Chemical exposure: Some flavouring compounds may form harmful by-products when heated.
  • Uncertain long-term effects: Research is still ongoing.
