Sweet Vape Juice: The Potential Health Risks of Flavourings

Electronic cigarettes, commonly known as vapes, have become increasingly popular, especially among young adults. Vaping devices work by heating a liquid, referred to as e-liquid or vape juice, to produce an aerosol that is inhaled. Vape juice comes in many flavours, including sweet ones such as fruit, candy, and dessert flavours.

However, some vapers may notice a sweet taste unrelated to the flavour they are vaping. This raises the question, does my vape juice contain sugar, and is it safe to vape? In this article, we will explore the answer to this question and the potential health risks associated with vaping sweet-tasting vape juice.

What is Vape Juice Made of?

Vape juice is a liquid that is used in electronic cigarettes. It is typically made up of four main ingredients: propylene glycol (PG), vegetable glycerine (VG), flavourings, and nicotine. PG and VG are food-grade liquids used in many products, including food, cosmetics, and pharmaceuticals. Flavourings used in vape juice are often made from natural or artificial ingredients, and they provide the unique taste and aroma of the vape juice. Nicotine is an optional ingredient that can be added to vape juice, and its concentration varies depending on the user's preference.

Does Vape Juice Contain Sugar?

The short answer is no; vape juice does not contain sugar. The sweetness in vape juice comes from the flavourings used, which can be natural or artificial. Many flavourings used in vape juice are derived from food and often contain sweeteners such as sucralose, stevia, or ethyl maltol. These sweeteners are not technically sugar but can still provide a sweet taste to the vape juice.

Is Sweet Vape Juice Safe to Vape?

While vape juice does not contain sugar, the sweeteners in flavourings can still have potential health risks. Sucralose, for example, has been shown to have negative effects on gut health and metabolism. Stevia is generally considered safe, but some studies suggest that it may hurt fertility. Ethyl maltol is generally considered safe but can irritate the throat and lungs in high concentrations. Additionally, some flavourings may contain diacetyl, which can cause a condition known as popcorn lung, a severe respiratory disease.

How Does Sweet Vape Juice Affect the Vaping Experience?

Sweet vape juice can enhance the vaping experience by providing a pleasant taste and aroma. However, too much sweetness can be overwhelming and may cause vapers to experience vape tongue, a condition where the taste buds become desensitised to the flavour. Additionally, sweeteners can cause the vape juice to gunk up coils faster, reducing vapour production and a burnt taste.

How Can I Tell if My Vape Juice Contains Sweeteners?

Most vape juice manufacturers list the ingredients used in their products on the packaging or website. If you are unsure whether your vape juice contains sweeteners, check the label or contact the manufacturer for more information. Additionally, many e-liquid flavourings contain reviews or comments from other vapers, which can provide insight into the flavour profile of the vape juice.

Are There Alternatives to Sweet Vape Juice?

Many alternatives are available if you are concerned about the potential health risks associated with sweet vape juice. Some vapers prefer to vape unflavoured e-liquid, which contains no added flavourings or sweeteners. Others may prefer vape juice with natural flavourings or no added sweeteners.


Vape juice does not contain sugar, but the sweeteners used in flavourings can still have potential health risks. While sweet vape juice can enhance the vaping experience, too much sweetness can overwhelm and cause adverse effects. Always check the label or contact the manufacturer for more information about the ingredients used in your vape juice.
