Is there Sugar in Vape Juice?

July 10, 2026 • 4 min read

Quick answer

Standard vape juice (e-liquid) does not contain traditional sugar (sucrose). The base ingredients are propylene glycol (PG), vegetable glycerin (VG), food-grade flavourings, and optional nicotine. Some e-liquids include sucralose, an artificial sweetener, in the flavouring component. Vuse e-liquids contain no added sucralose.

What is vape juice made of?

E-liquid (also called vape juice or vape liquid) is formulated from a small number of core ingredients:
 

  • Ingredient: propylene glycol (PG)
    • Role: carries flavour; produces throat sensation; thinner consistency
    • Typical proportion: 20–50% of base
  • Ingredient: vegetable glycerin (VG)
    • Role: produces vapour volume; slightly sweet taste naturally; thicker consistency
    • Typical proportion: 50–80% of base
  • Ingredient: flavourings
    • Role: food-grade concentrates providing taste profile
    • Typical proportion: 1–20% depending on formulation
  • Ingredient: nicotine (optional)
    • Role: available as freebase or nicotine salt; 0–20 mg/mL (TVPA cap)
    • Typical proportion: variable (0 mg/mL to 20 mg/mL)
  • Ingredient: distilled water (optional)
    • Role: reduces viscosity in some formulations
    • Typical proportion: trace amounts if used

Does vegetable glycerin (VG) count as sugar?

Vegetable glycerin (VG) is a sugar alcohol derived from plant oils. It has a naturally mild sweet taste and provides the thick, cloud-producing properties of an e-liquid. However, VG is not sucrose (table sugar), fructose, or glucose. It is classified as a humectant and sweetener (E422) in food applications but is metabolised differently from conventional sugars.
 

VG is widely used in food and cosmetic applications, as recognised by regulatory bodies in North America and Europe. Its presence in e-liquid is primarily for vapour production, not sweetness.
 

Sucralose in e-liquid: what you need to know
 

Some flavoured e-liquids, particularly those with dessert, candy, or fruit profiles, include sucralose as a sweetener. Sucralose is a zero-calorie artificial sweetener approximately 600 times sweeter than sugar by weight.
 

Key facts about sucralose in e-liquid:
 

  • Sucralose is not the same as sugar. It is a chlorinated sucrose derivative that passes through the body largely unmetabolised.
  • When heated and vaporized, sucralose and similar sweeteners contribute to coil degradation; sweet e-liquids are associated with faster coil gunking due to caramelization residue on the coil cotton.
  • Not all e-liquids contain sucralose. Many flavour concentrates are formulated without sweeteners.
  • Under the TVPA, it is required that manufacturers report e-liquid ingredients including flavourings and any sweeteners.
     

Puff frequency and duration
 

Each puff activates the heating element and drains the battery. Frequent, long draws accelerate depletion. An adult nicotine consumer taking 300 puffs per day will drain the battery significantly faster than one taking 75 puffs per day on the same device.
 

Vuse e-liquids: no added sucralose
 

Vuse e-liquids are formulated without any added sucralose. For full ingredient information, visit the Vuse E-Liquids Done Right page.

 

Why e-liquid sweetness doesn't always mean sucralose
 

Many adult nicotine consumers report sweet-tasting e-liquids that contain no sucralose whatsoever. This perceived sweetness can come from:

  • The natural mild sweetness of VG itself.
  • Flavouring concentrates designed to mimic sweet tastes without using sweetener additives.
  • Nicotine format: usually nicotine salt (20 mg/mL in most Canadian-compliant versions).
  • Certain naturally derived flavour esters that produce sweet olfactory perception.
     

How sucralose-free e-liquids affect coil life
 

Sucralose caramelizes at vaping temperatures and deposits a dark, sticky residue (gunking) on the coil cotton. This residue reduces wicking efficiency, degrades flavour quality, and shortens coil life, sometimes dramatically, to only a few days for heavy adult nicotine consumers of heavily sweetened e-liquids.
 

E-liquids formulated without added sweeteners like sucralose produce significantly less coil residue, extending coil and pod life.
 

Canadian regulatory framework for e-liquid ingredients
 

Under the TVPA, manufacturers of vaping products sold in Canada must:
 

  • Report all ingredients in e-liquid, including flavourings and any sweeteners, to Health Canada.
  • Disclose emissions data from the product when heated to vaporization temperature.
  • Not include ingredients on Health Canada's list of prohibited substances.
  • Label products with required health information, including nicotine content.

Frequently Asked Questions

Standard e-liquid does not contain sucrose (table sugar). The naturally mild sweetness comes primarily from vegetable glycerin (VG). Some formulations add sucralose as a flavour enhancer — but Vuse e-liquids contain no added sucralose.

No. Vuse e-liquids are formulated without added sucralose. See eliquids done right for Vuse's full ingredient commitment.

Sucralose and certain sweeteners caramelize when repeatedly exposed to high heat on the coil cotton, forming a dark, thick residue. This is why heavily sweetened e-liquids are associated with shorter coil life. Sucralose-free formulas like Vuse produce less of this residue.

 No. Vegetable glycerin (VG) is not a conventional sugar and is processed differently by the body. In vaping products, VG is used to produce aerosol rather than being consumed as a food ingredient.

Canadian vaping products regulated under the TVPA must include ingredient information. Check the product label and packaging, or consult the brand's website. Vuse's ingredient transparency can be found at eliquids done right.
