E-liquid, also known as vape juice or e-juice, is the substance used in electronic cigarettes (e-cigarettes) that gets vaporised to produce vapour. Unlike traditional cigarettes, which burn tobacco to create smoke, e-cigarettes heat e-liquid to generate vapour, which is then inhaled by the user. The primary purpose of e-liquid is to deliver nicotine in a way that mimics smoking but without the harmful by-products of combustion, such as tar and many toxic chemicals.

E-liquids come in a variety of flavours, ranging from traditional tobacco and menthol to more adventurous choices like mixed fruit, dessert, and even cocktail flavours. This range of flavours allows users to personalise their vaping experience according to their tastes. Furthermore, e-liquids can contain varying levels of nicotine from nicotine-free to high-strength liquids, making them suitable for a broad spectrum of users—from those looking to quit smoking to those who simply enjoy vaping as a hobby.

The main ingredients in e-liquid are relatively straightforward and typically include Propylene Glycol (PG), Vegetable Glycerine (VG), flavourings, and nicotine. PG and VG serve as the base liquids that carry the flavours and nicotine.

Propylene Glycol (PG): PG is a colourless, tasteless liquid that serves as a carrier for the flavourings. High PG liquid is known for providing a strong throat hit, which many ex-smokers find satisfying. PG is used in various consumer products, including food and medicinal inhalers, making it a trusted ingredient in e-liquids.

Vegetable Glycerine (VG): VG is a thicker, sweeter liquid that contributes to the amount of vapour produced. High VG e-liquids are known for producing large, dense clouds, making them popular among cloud chasers. VG is derived from vegetable oils and is also commonly used in food, cosmetics, and pharmaceuticals.

Flavourings: These are food-grade additives that provide the vast array of flavours available in e-liquids. From fruits and desserts to traditional tobacco and menthol, the options are almost limitless. The quality of the flavourings can significantly impact the overall vaping experience, so reputable manufacturers use high-quality ingredients.

Nicotine: This is the optional ingredient in e-liquids. Available in various concentrations, nicotine gives users the experience closest to smoking traditional cigarettes. Nicotine-free options are also available for those who enjoy vaping without the addictive substance.

To maintain the quality and longevity of your e-liquid, store it in a cool, dark place away from direct sunlight and heat sources. A cupboard or drawer is ideal. Ensure the bottles are tightly closed to prevent oxidation.

When it comes to safety, e-liquids are generally considered to be significantly less harmful than traditional cigarettes. This is because they do not involve the combustion of tobacco, which produces thousands of harmful chemicals, including carcinogens. However, it’s essential to note that "safe" does not mean "without risk." Here are some crucial points to consider:

Ingredients: E-liquids produced by reputable manufacturers use high-quality, food-grade ingredients. Always buy from trusted brands to ensure the products meet safety and regulatory standards.

Nicotine: While nicotine is addictive and has its own set of health risks, e-liquids allow users to control their nicotine intake. This controlled consumption can be a safer alternative to smoking and a useful tool for quitting.

Usage and Maintenance: Proper use and maintenance of vaping devices are crucial for safety. Always follow the manufacturer's guidelines and ensure your device is in good working condition. Misuse, such as using incorrect wattage or failing to keep the device clean, can lead to health risks, including inhaling harmful substances or causing device malfunctions.

Regulations: In the UK, e-liquids must comply with strict regulations enforced by agencies like the Medicines and Healthcare products Regulatory Agency (MHRA) and the Tobacco Products Directive. These regulations ensure that products are safe for consumption and free from harmful ingredients.

While e-liquids are not completely without risks, they are generally a safer alternative to smoking traditional cigarettes, especially when purchased from reputable sources and used correctly.

Many people turn to vaping as a means to quit smoking, and e-liquids play a crucial role in this transition. Vaping can mimic the act of smoking, providing both the physical sensation and nicotine that smokers crave. Here’s how e-liquids can help you quit smoking:

Nicotine Control: One of the significant advantages of e-liquids is the ability to control nicotine intake. E-liquids come in various nicotine strengths, allowing you to start at a level that matches your current smoking habits and gradually reduce your intake over time. This tapering method can be effective for quitting smoking.

Physical Habit: Vaping replicates the hand-to-mouth action that many smokers find difficult to give up. This can make the transition from smoking to vaping smoother, as it addresses both the psychological and physical aspects of nicotine addiction.

Flavour Variety: The wide range of flavours available can make vaping a more enjoyable experience compared to smoking. This variety can help keep you engaged in the process of quitting, as you can experiment with different flavours until you find what you like best.

Immediate Benefits: Users often report immediate benefits when they switch from smoking to vaping, such as improved taste and smell, better lung function, and overall well-being. These improvements can provide positive reinforcement to stay off cigarettes.

Scientific Support: Studies have shown that vaping is an effective tool for smoking cessation. According to Public Health England, e-cigarettes are estimated to be approximately 95% less harmful than smoking. Many smokers have successfully quit smoking by transitioning to vaping and eventually reducing their nicotine intake to zero.

While e-liquids and vaping devices can significantly aid in smoking cessation, the best results are often seen when combined with a strong commitment and possibly other support methods, such as counselling or smoking cessation programmes.

Choosing the right nicotine strength in your e-liquid is critical for a satisfying vaping experience and can also aid in your efforts to quit smoking. Here’s how to make an informed choice:

Understand Your Smoking Habits: The first step is to evaluate how many cigarettes you currently smoke per day. This will help you choose a nicotine strength that matches your current nicotine intake and can help you avoid under- or over-consuming nicotine.

●    Heavy Smokers (20+ cigarettes/day): If you’re a heavy smoker, look for e-liquids with high nicotine levels, around 18-20mg/mL. This strength is designed to satisfy your nicotine cravings and prevent withdrawal symptoms.

●    Moderate Smokers (10-20 cigarettes/day): For moderate smokers, a nicotine strength of 12-18mg/mL is usually sufficient. This level provides a balance between satisfying cravings and reducing nicotine consumption.

●    Light Smokers (<10 cigarettes/day): If you’re a light smoker, you can opt for lower nicotine levels, around 3-6mg/mL. This strength can help you transition away from smoking without overwhelming your system with nicotine.

●    Non-Smokers or Occasional Smokers: If you’re not a smoker or are an occasional smoker, consider starting with 0mg nicotine e-liquids. This allows you to enjoy the flavours and experience of vaping without the addictive substance.

Consider the Throat Hit: Nicotine contributes to the throat hit, which many ex-smokers find satisfying. Higher nicotine levels provide a more substantial throat hit, while lower levels offer a smoother experience. If you prefer a harsh hit, opt for higher nicotine; if you want a gentle hit, go for lower nicotine.

Experiment and Adjust: It may take some trial and error to find the perfect nicotine strength for you. Start with a level that closely matches your smoking habits and adjust as needed. Some vapers keep multiple bottles with different nicotine strengths to manage their cravings throughout the day.

Seek Advice: Don’t hesitate to consult with experienced vapers or contact the Go Smoke Free team for personalised advice. They can guide you based on your smoking history and vaping goals.

Choosing the right nicotine strength is essential for a satisfying and effective vaping experience. Take your time to understand your needs and make adjustments as necessary.

Propylene Glycol (PG) and Vegetable Glycerine (VG) are the two primary base liquids in e-liquids. Their roles and characteristics significantly impact your vaping experience, so understanding them is crucial.

Choosing the right PG/VG ratio depends on your personal preferences and vaping style. Understanding their roles helps you make an informed decision to enhance your vaping experience.

Whether a higher VG (Vegetable Glycerine) is better than a higher PG (Propylene Glycol) depends on your preferences and vaping style. VG and PG each have distinct characteristics that cater to different experiences.

High VG e-liquids are known for producing thick, dense vapour clouds, making them a favourite among cloud chasers. VG offers a smoother throat hit, which is less harsh and easier on the throat. Its thicker consistency also adds a slight sweetness to the vapour. However, VG can cause a build-up in your device and might require more frequent cleaning.

High PG e-liquids, on the other hand, are excellent for flavour delivery and provide a stronger throat hit, closely mimicking the sensation of smoking. PG’s thinner consistency makes it less likely to cause build-up but can be harsh on the throat, especially at higher nicotine levels.

Yes, e-liquid can expire. Depending on storage conditions, it usually has a shelf life of 1–2 years. Check the expiry date on the bottle and look out for changes in colour or taste, which might indicate the e-liquid has gone off.

Freebase nicotine is the most common form found in traditional e-liquids. It is created through a chemical process that makes the nicotine more potent and allows it to vaporise at lower temperatures. This form of nicotine is known for delivering a strong throat hit, closely resembling the sensation of smoking a traditional cigarette. However, at higher concentrations, freebase nicotine can become harsh, which might not be suitable for everyone.

Nicotine salts, on the other hand, are a more recent innovation. They are created by combining pure nicotine with an organic acid, usually benzoic acid. This combination results in a nicotine form that absorbs more quickly into the bloodstream and provides a smoother throat hit, even at higher concentrations. Nicotine salts are particularly beneficial for heavy smokers looking to transition to vaping, as they offer a more immediate and satisfying nicotine hit.

Choosing the right e-liquid flavour can be a fun but sometimes overwhelming process, given the vast array of options available. The best approach is to start with what you know and love. If you’re transitioning from smoking, you might want to begin with tobacco or menthol flavours, as these can provide a sense of familiarity. Once you’re comfortable, you can explore more adventurous flavours like fruits, desserts, or beverages. Reading reviews and asking for recommendations from other vapers can also guide you towards popular and well-loved flavours.

Your personal preferences will play a significant role in your choice. Are you drawn to fruity, sweet, or savoury flavours? Do you prefer something that mimics the taste of a cigarette, or are you open to exotic and unique blends? Keep an open mind and don’t be afraid to try something new; you might just find your new favourite flavour!

A burnt taste in your e-liquid is often a sign that your coil is dry or burnt out. When the coil inside your vape device isn’t adequately saturated with e-liquid, it can burn the wicking material, resulting in an unpleasant taste.

Switching e-liquid flavours without mixing residuals from the previous flavour requires a bit of care. Here’s how to do it effectively:

1. Disassemble Your Device: Start by taking apart your vape tank and removing the coil.

2. Rinse the Tank: Rinse the tank components (excluding the coil) under warm water to remove any leftover e-liquid. For a more thorough clean, you can use a mixture of warm water and mild dish soap. Ensure all soap is completely rinsed off.

3. Dry the Components: Use a paper towel to pat dry the components or let them air dry completely. Any remaining water can dilute the new e-liquid and affect the flavour.

4. Replace the Coil: If you’re changing to a dramatically different flavour, it might be wise to start with a new coil. Residual e-liquid in the old coil can impact the new flavour.

5. Prime the New Coil: If you’re using a new coil, don’t forget to prime it. Apply a few drops of the new e-liquid to the coil's wicking material and let it sit for a few minutes before reassembling the tank.

6. Reassemble and Fill: Reassemble your vape tank and fill it with the new e-liquid. Allow it to sit for a few minutes to ensure the coil is fully saturated before you start vaping.

If your e-liquid starts leaking, it can be frustrating and messy! There are many reasons why e-liquid can begin to leak from your device, from loose components and overfilling to improper coil installation and even environmental changes. Taking the time to get to know your device and following all of the manufacturer's guidance can help ensure you avoid leakage.

While e-liquids are generally considered safer than traditional cigarettes, they are not entirely without side effects. Common side effects include:

Dry Mouth and Throat: The PG in e-liquids can absorb moisture and lead to dryness of the mouth and throat. Staying hydrated can help alleviate this issue.

Coughing: New vapers might experience a slight cough when transitioning from smoking to vaping. This usually diminishes as your body adjusts.

Dizziness: Consuming too much nicotine too quickly can lead to light-headedness or dizziness. If this occurs, consider lowering your nicotine strength or taking longer breaks between vaping sessions.

Allergic Reactions: Some users might be sensitive or allergic to PG. Symptoms can include dry mouth, throat irritation, or mild rashes. Switching to a higher VG e-liquid can often solve this problem.

Headaches: Dehydration can lead to headaches, so make sure to drink plenty of water while vaping.

Nicotine Addiction: Nicotine is an addictive substance. While e-liquids allow you to control your nicotine intake, it’s crucial to manage your consumption to avoid dependence.

It’s always advisable to consult with a healthcare professional if you experience persistent or severe side effects.

Regular cleaning of your vape tank is essential to maintain its performance and flavour quality. Here’s a step-by-step guide to keep your vape tank clean:

1. Disassemble Your Tank: Remove the tank from the battery and disassemble all parts, including the coil, tank, and mouthpiece.

2. Rinse Under Warm Water: Rinse all parts (except the coil) under warm running water. For a more thorough clean, use a mixture of warm water and mild dish soap.

3. Use a Cleaning Brush: For stubborn residue, use a small cleaning brush or an old toothbrush to scrub the tank components gently.

4. Soak for Deep Cleaning: For a deeper clean, you can soak the tank components in a bowl of warm water mixed with a bit of vinegar or baking soda for 15-30 minutes before rinsing thoroughly.

5. Dry Completely: Pat the components dry with a paper towel and allow them to air dry completely. Any remaining moisture can affect the performance and flavour of your e-liquid.

6. Clean the Coil and Mouthpiece: Use a cotton swab dipped in rubbing alcohol to clean the coil’s outer parts and the inside of the mouthpiece.

7. Reassemble and Prime: Once all parts are completely dry, reassemble your tank and prime the coil if it’s new.

Steeping is the process of allowing your e-liquid to mature, enhancing its flavour by letting the ingredients blend more thoroughly. The process is similar to letting a fine wine age. While not all e-liquids require steeping, many benefit from it, especially those with complex flavour profiles.

Here’s how you can steep your e-liquid:

1. Shake Well: Start by shaking the e-liquid bottle to ensure all the ingredients are well-mixed.

2. Store in a Cool, Dark Place: Store the e-liquid in a cool, dark place like a cupboard. Avoid exposing it to sunlight or high temperatures, as this can degrade the nicotine and flavourings.

3. Remove the Cap: Some vapers prefer to let the bottle "breathe" by removing the cap for a few hours before sealing it again. This can help to dissipate any harsh alcohol or chemical notes.

4. Shake Regularly: Periodically, give the bottle a good shake to help the steeping process.

5. Give It Time: Steeping can take anywhere from a few days to a few weeks, depending on the complexity of the flavours. You can taste-test periodically to see if the flavours have developed to your liking.

6. Speed Steeping: If you’re in a hurry, some methods like warm water baths can accelerate the steeping process. Just be cautious not to expose the e-liquid to too much heat.

Ensuring your e-liquid is of high quality is crucial for a satisfying and safe vaping experience. Reputable Manufacturer: Always buy from reputable brands and vendors. High-quality e-liquids are usually produced by well-known manufacturers who follow stringent safety and quality control standards.

Remember! Making your own e-liquid can be rewarding but requires caution to ensure safety and quality.

Ensuring your e-liquid is compatible with your vape device is crucial for both performance and satisfaction. The two primary factors to consider are the VG/PG ratio and nicotine strength.

VG/PG Ratio:  Devices with sub-ohm coils (below 1.0 ohm) are designed to handle high VG e-liquids (70% VG or more), which are thicker and produce larger vapour clouds. Regular vape starter kits and devices with higher resistance coils work better with high PG e-liquids (50% PG or more), which are thinner and provide a stronger throat hit. Always check your device's specifications for the recommended VG/PG ratio.

Nicotine Strength: The nicotine level can affect both the throat hit and overall experience. High nicotine e-liquids (12-20mg/mL) are ideal for devices with higher resistance coils that operate at lower wattages. Low nicotine e-liquids (3-6mg/mL) are well-suited for sub-ohm devices that vaporise e-liquid more efficiently, producing larger clouds. Using a nicotine level that’s too high in a sub-ohm device can result in a harsh, unpleasant experience.

Device Specifications: Manufacturers often provide guidelines on the best e-liquid ratios and nicotine levels for their devices. Reviewing the user manual or visiting the manufacturer's website can offer valuable insights to ensure compatibility.

The duration a bottle of e-liquid lasts can vary widely depending on several factors, including your vaping habits, device efficiency, and the size of the bottle.

Vaping Frequency: If you’re a heavy vaper who enjoys substantial, frequent clouds, you’ll naturally go through e-liquid more quickly. Conversely, occasional or moderate vapers will find their e-liquid lasting longer.

Device Efficiency: High-powered devices vaporise e-liquid faster than low-powered ones. Sub-ohm devices, which are designed for creating large vapour clouds, tend to consume more e-liquid compared to standard vape pens with higher resistance coils.

Nicotine Level: Higher nicotine concentrations can curb your desire to vape frequently, potentially extending the life of your e-liquid. If you’re using a high nicotine strength, you might find yourself taking fewer puffs, which conserves your supply.

Average Consumption: On average, moderate vapers use about 2-3ml of e-liquid per day. However, this can vary based on the factors mentioned above.
