What is Vape Juice Made Of?

Vape juice, also known as e-liquid or e-juice, is primarily composed of four main ingredients: Propylene Glycol (PG), Vegetable Glycerine (VG), nicotine, and flavourings (1).

1. Propylene Glycol is a colourless, odourless liquid that provides a strong throat hit, similar to smoking tobacco, and serves as a carrier for the flavourings (2).
2. Vegetable Glycerine is a thicker, sweeter liquid that produces dense vapour clouds and smoothens the overall vaping experience.
3. Nicotine, an optional component, is the addictive substance found in traditional cigarettes and comes in various strengths to suit different preferences.
4. Flavourings, which can range from fruit and dessert to menthol and tobacco, give vape juice its distinct taste and aroma.

Together, these ingredients create the vaping experience that has become popular among many users.

What is vape juice for?

Vape juice, also known as e-liquid or e-juice, serves as the primary substance used in vaping devices to create vapour. Its primary purpose is to deliver flavour and, in many cases, nicotine to the user. When heated by the vape device, vape juice transforms into an aerosol that is inhaled, providing a sensory experience akin to smoking but without combustion. Beyond nicotine, vape juice comes in a variety of flavours, allowing users to enjoy a range of tastes from fruity and sweet to savoury and spicy. Additionally, vape juice can be formulated without nicotine, catering to those who enjoy vaping purely for the flavours and vapour production. Ultimately, vape juice is designed to enhance the vaping experience by offering both pleasure and satisfaction through its flavours and, when included, its nicotine content.

Do Flavoured Vapes Have Nicotine?

Do flavoured vapes have nicotine? The answer depends on the specific product. Many flavoured vapes do contain nicotine, catering to users who are looking for a smoking alternative with the same addictive substance. However, there are also numerous nicotine-free options available for those who enjoy a range of flavours without the associated nicotine. It's essential for users to check the packaging and product descriptions to determine the nicotine content of any flavoured vape they purchase. This ensures they can make an informed decision based on their personal preferences and health considerations.

Does the Type of Nicotine Affect the Vape Juice?

Yes, the type of nicotine significantly affects the vape juice and the overall vaping experience. There are primarily two types of nicotine used in vape juices: freebase nicotine and nicotine salts. Freebase nicotine, the traditional form, provides a stronger throat hit and is typically found in higher concentrations. Nicotine salts, sometimes just called 'nic salt', are derived from the natural state of nicotine in tobacco leaves and are formulated to be smoother and less harsh on the throat, even at higher concentrations. This means that vape juices with nicotine salts can deliver a higher nicotine content with a more enjoyable and less irritating experience, making them popular among those seeking a quick and potent nicotine fix. The choice between these types ultimately depends on personal preference and desired vaping experience.

What are shortfill e-liquids?

Shortfill e-liquids are a type of nicotine-free e-liquid that comes in a bottle larger than the standard 10ml size but with a deliberate gap at the top, leaving space for additional nicotine shots, also known as 'nic shots'. Typically available in 60ml or 120ml bottles, shortfills are designed to be mixed with nicotine boosters or nicotine salts to achieve the desired nicotine strength. The thinking is that you add the 10ml nicotine shot to your 50ml shortfill to give you a total of 60ml of custom e-liquid, or a 20ml nicotine shot to your 100ml shortfill bottles to make 120ml of vape juice.

The practice of using shortfills allows vapers to customise their nicotine levels for the perfect nicotine strength while adhering to UK regulations that limit the sale of nicotine-containing e-liquids to 10ml bottles (3). This flexibility makes shortfills popular among vapers who prefer to mix their own nicotine levels without compromising on the volume of e-liquid they purchase. In addition to their practical benefits, shortfills come in a wide range of flavours, offering a versatile vaping experience tailored to individual preferences.

What kind of vape juice do disposable vapes use?

Disposable vapes typically use a specific kind of vape juice formulated to complement their design and functionality. These devices often utilise nic salts rather than freebase nicotine. Nic salts provide a smoother throat hit and higher nicotine concentrations, which is ideal for disposable vapes designed for quick, satisfying nicotine delivery. The vape juice in disposable vapes usually features a balanced blend of Propylene Glycol (PG) and Vegetable Glycerine (VG), ensuring an optimal mix of flavour delivery and vapour production. Additionally, the disposable vape flavours are varied and vibrant, ranging from traditional tobacco and menthol to an array of fruit, dessert, and beverage-inspired options, catering to diverse user preferences.

Disposable vape users should be aware that a disposable vape ban is coming into effect in the UK in 2025 in order to tackle the environmental impact of disposable vapes and the increase in youth vaping. (4)

Can Vape Juice Go Bad?

Yes, vape juice can go bad over time, and its quality may degrade if not stored properly. Vape juice typically has a shelf life of about one to two years, but its longevity depends on factors like exposure to light, heat, and air. Over time, the flavourings can lose their potency, and the nicotine content can diminish or change in taste. Signs that vape juice has gone bad include a change in colour, a rancid or off-putting odour, or an altered flavour. To maximise its shelf life, vape juice should be stored in a cool, dark place, away from direct sunlight and extreme temperatures. If you notice any of these signs, it's best to discard the vape juice to avoid an unpleasant vaping experience.

Can You Use Expired Vape Liquid?

Using expired vape liquid is generally not recommended, as its quality and safety may be compromised. Over time, expired vape juice can undergo chemical changes that affect its flavour, nicotine potency, and overall effectiveness. This degradation can result in a less enjoyable vaping experience and, in some cases, may even cause irritation or adverse reactions. Additionally, expired vape juice may not vaporise properly, leading to poor performance. To ensure the best experience and avoid potential health risks, it's advisable to replace expired vape liquid with fresh, properly stored e-juice. Always check the expiration date and condition of your vape liquid before use.

Can You Put Any E-Liquid in Any Vape?

No, you can't put just any e-liquid in any vape device; compatibility is crucial for optimal performance. Vape devices and e-liquids vary in their composition, specifically in their Propylene Glycol (PG) to Vegetable Glycerin (VG) ratio, which affects viscosity and vapour production. For instance, high-VG makes for thicker e-liquids and better suited for sub-ohm tanks that can handle larger vapour volumes, while high-PG e-liquids are thinner and generally work better with pod systems or smaller tanks. Additionally, using e-liquids with nicotine salts in devices designed for freebase nicotine can affect the throat hit and overall experience. It's important to match the e-liquid's properties with your device's specifications to ensure efficient vaporisation, avoid potential damage, and enjoy a satisfying vaping experience.

What Strength Vape Juice Should I Choose?

Choosing the right strength of vape juice depends on your personal nicotine needs and vaping habits. If you're new to vaping or trying to transition from smoking, starting with a moderate nicotine strength—typically between 3mg to 6mg—might be suitable, as it provides a good balance between throat hit and satisfaction. For those who are heavy smokers or need a stronger nicotine hit, higher strengths such as 12mg to 18mg may be more appropriate. Conversely, if you prefer a milder experience or are aiming to reduce nicotine intake, opting for lower strengths like 0mg or 1.5mg can be beneficial. Additionally, nicotine salts are available in various strengths and offer a smoother throat hit, making them a popular choice for those who require higher nicotine levels without the harshness. Ultimately, your choice should reflect your individual needs and preferences for both nicotine content and throat hit.

What is the best vape juice for quitting smoking?

The best vape juice for quitting smoking is one that aligns with your nicotine needs and preferences to effectively manage cravings while offering a satisfying vaping experience. Typically, e-liquids with nicotine salts are favoured for this purpose because they apparently deliver nicotine more smoothly and efficiently, mimicking the quick nicotine absorption of traditional cigarettes. Opt for vape juices that provide a range of nicotine strengths, allowing you to start at a higher concentration and gradually reduce it as you progress in your quitting journey. Additionally, select flavours that you find enjoyable and comforting, as this can make the transition from smoking more pleasant. Popular choices often include classic tobacco flavour, which closely resemble the taste of cigarettes, or menthols, which provide a cooling effect similar to menthol cigarettes. Ultimately, the best vape juice for quitting smoking is one that supports your nicotine reduction goals while making the experience enjoyable and manageable.

Why are UK-made liquids considered the best?

UK-made vape liquids are often considered among the best due to their adherence to stringent quality and safety standards set by regulatory bodies such as the Tobacco and Related Products Regulations (TRPR). These regulations ensure that e-liquids meet high manufacturing and labelling standards, including accurate nicotine content and ingredient transparency. Additionally, UK vape liquid manufacturers are known for their rigorous quality control processes, which involve thorough testing for consistency, purity, and flavour accuracy. The emphasis on high-quality ingredients and adherence to safety protocols contributes to a reliable and enjoyable vaping experience. Furthermore, many UK-made e-liquids feature innovative and well-crafted flavour profiles that cater to diverse tastes, enhancing their reputation for excellence in the vaping community. These high standards reflect the findings from Public Health England that E-Cigarettes are at least 95% less harmful than smoking.

Despite this, a survey from Action on Smoking and Health found that 40% of UK smokers wrongly believe that vaping is as harmful or even worse than smoking! (5) 

Best Vape Flavours UK

In the UK, the best e-liquid flavours cater to a wide range of tastes, reflecting diverse preferences among vapers. Popular choices include classic fruit flavours like strawberry, mango, and blueberry, which provide a refreshing and vibrant vaping experience. Dessert-inspired flavours, such as custard, caramel, and doughnut, are also highly sought after for their rich, indulgent profiles. Menthol and mint flavours are favored for their cooling sensation and crispness, making them ideal for a refreshing vape. Additionally, traditional tobacco flavours remain a staple for those transitioning from smoking. With a growing selection of innovative and unique blends, including combinations of fruits, desserts, and beverages, the UK vaping market offers something for everyone, ensuring that vapers can find their perfect flavour match.
