How to Add Nicotine to Vape Juice

You measure, you mix, you shake – adding nicotine to vape juice is a process that's straightforward but requires precision. As you embark on customizing your vaping experience, it's crucial you're familiar with the basics.

Nicotine shots, or 'nic shots', allow you to infuse varying strengths of nicotine into your favourite e-liquids. You'll need to select the right volume and concentration of nicotine to blend with your shortfill bottle, ensuring you achieve the throat hit and satisfaction you're after.

This short guide will provide you with the knowledge to calculate nicotine strength, mix effectively, and handle nicotine safely. By the end, you'll have the tools to tailor your vape juice to your personal preference, all while maintaining the integrity of the flavour.

Let's get into the nitty-gritty of how to add nicotine to your vape juice with confidence.

Understanding Nicotine Shots

Nicotine shots, often referred to as 'nic shots', are small 10ml bottles that you'll add to your vape juice to reach your desired nicotine strength. These concentrated nicotine solutions are designed to be mixed with shortfill e-liquids, which are larger bottles of vape juice that come without nicotine. When you're understanding nicotine shots, it's crucial to know that they typically contain a high level of nicotine, which, when added to your shortfill, dilutes to the strength you prefer.

To achieve your desired nicotine strength, first, calculate how much of the nicotine shot you need to add to your e-liquid. For instance, adding one 18mg nic shot to a 50ml shortfill will typically create a 3mg nicotine e-liquid. Pour the required amount of nicotine shot into your shortfill bottle, and then you must shake the liquid vigorously. This ensures that the nicotine solution is evenly distributed throughout the e-liquid. Once mixed, your vape juice is ready to use.

Selecting Your Shortfill Bottle

When you're ready to mix in your nicotine shot, you'll need to pick out a shortfill bottle that best suits your vaping needs. Shortfill e-liquids are designed to accommodate additional nicotine, offering you the flexibility to create a vape juice with your desired strength. The selection process should be methodical, ensuring you achieve the perfect blend for a satisfying experience.

Consider the bottle size of your shortfill; it determines the amount of space available for your nicotine shot. Typically, a 50ml shortfill in a 60ml bottle will leave adequate room for a single 10ml nicotine shot. This is essential when aiming for higher nicotine concentrations without the need to transfer to a larger container.

Pay attention to the VG/PG ratio of the shortfill e-liquids, as this affects the compatibility with your nic shot. For a smoother throat hit and thicker vapor, look for a higher VG formula. Conversely, a higher PG ratio is suitable for those seeking a more pronounced flavour and stronger throat hit.

To conclude, selecting the right shortfill bottle is a critical step in customizing your vape juice. Balance your preference for flavour, throat hit, and vapor production with the space needed for your desired nicotine strength to ensure a tailored vaping experience.

Calculating Nicotine Strength

To accurately determine how much nicotine you'll need to achieve your desired strength, it's essential to do some simple math.

First, decide your desired nicotine strength for the end mixture. Let's say you aim for a 3mg strength in a 60ml bottle.

If you're adding an 18mg nicotine shot, the calculation would be as follows: the volume of the e-liquid (60ml) multiplied by the desired strength (3mg) divided by the strength of the nicotine shot (18mg). This gives you the amount of liquid nicotine required, which in this case is 10ml.

Next, ensure you're adding the right volume of this nicotine shot to your base liquid. After pouring the nic shot into the e-liquid, securely replace the bottle cap and shake the liquid vigorously. It's crucial to shake well to ensure the nicotine is evenly distributed throughout the e-liquid.

Remember, the more precise you are with your measurements, the more accurate your nicotine strength will be.

Preparing for Nicotine Mixing

Before you start mixing, ensure you've got all the necessary supplies, including your nicotine shot, e-liquid base, syringe or pipette, gloves, and a clean workspace. Preparing for nicotine mixing is a critical step in the process to achieve the desired nicotine strength in your vape juice.

To begin, calculate the amount of nicotine you'll need based on the strength you want. Adding the right amount of liquid nicotine to your base is key. If you're aiming for a specific nicotine level, precision is essential. Use a syringe or pipette for accurate measurement. Remember, the concentration of the nicotine shot and the volume of your e-liquid base will dictate how much to add.

After introducing the nicotine to the base, it's time to shake the liquid thoroughly. This ensures that the nicotine disperses evenly throughout the e-liquid. Don gloves to protect your skin and avoid contamination. Once the liquid appears homogeneous, you'll know the mixing is complete.

How To Mix Nicotine With Vape Juice

You'll need to carefully measure the nicotine shot to mix it with your e-liquid, ensuring the desired strength is achieved. Begin by determining the amount of nicotine you'll need for your desired nicotine strength. For shortfill e-liquids, which typically have space to add nicotine, you must calculate the volume of nicotine shot required. Adding a nicotine shot to a 50ml shortfill, for example, will usually raise the nicotine level to 3mg in a 60ml bottle.

Once you have the correct measurement, slowly add the nicotine shot to your e-liquid, taking care not to spill any. After you've added the nicotine, it's crucial to shake the liquid vigorously. This step is essential as it ensures that the nicotine is evenly distributed throughout the e-liquid. Failing to do so can result in uneven nicotine concentration when you vape, which can be unpleasant and unsatisfying.

After mixing, let the e-liquid sit for a few minutes to allow any air bubbles to settle. Then, give it another shake for good measure before filling your vape device. With these methodical steps, you've successfully completed mixing nicotine with e-liquid, tailored to your vaping preferences.

Safety Measures for Handling

Always wear protective gloves and eyewear when handling nicotine shots to prevent skin and eye exposure. This is one of the crucial safety measures for handling concentrated nicotine. The potent nature of nicotine means that any contact with your skin could result in nicotine absorption, which can be harmful. It's particularly important for persons who should avoid using nicotine, such as pregnant women and minors, to stay clear of direct contact.

When preparing to add nicotine to your vape juice to achieve the desired nicotine strength, ensure you're in a well-ventilated area. Spills should be cleaned immediately, and all bottles should be tightly sealed after use. Before you shake the liquid to mix the nicotine evenly, double-check that the cap is secure to prevent accidental splashes or spills.

Always keep nicotine and the e-liquids you're mixing out of reach of children and pets. Nicotine is a toxin, and ingestion can be extremely dangerous.

Finally, dispose of any leftover nicotine or empty bottles responsibly, keeping in mind the potential harm to the environment and others.

Follow these guidelines meticulously to maintain a safe and enjoyable vaping experience.

Assessing E-liquid Quality

While ensuring you've taken all necessary safety precautions, it's also critical to assess the quality of your e-liquid before adding nicotine to guarantee a satisfying vape experience. Begin by examining the e-liquid's clarity and color. A clear, untainted liquid generally indicates no unwanted oxidation or contamination. If the e-liquid appears cloudy or has an off-color, consider sourcing a better product.

Next, confirm the e-liquid's expiration date. Aged e-liquids can degrade, affecting both taste and safety. Always use fresh e-liquid to maintain the integrity of your e-cigarette use. Additionally, check the label for the vegetable glycerin (VG) to propylene glycol (PG) ratio. This balance influences both flavor delivery and vapor production.

Before adding nicotine, determine your desired nicotine strength. This is crucial for a tailored vape experience and to avoid over-consumption of nicotine. Use a reliable nicotine calculator if you're unsure about the measurements.

Maintenance and Storage Tips

After you've added nicotine to your vape juice, it's crucial to maintain and store your e-liquid properly to preserve its quality and extend its shelf life.

Once you've achieved the desired nicotine strength by adding the right amount of nicotine, always remember to shake the liquid thoroughly. This ensures the nicotine is evenly distributed throughout the e-liquid, providing a consistent experience with every vape.

To make sure the nicotine doesn't degrade, keep your e-liquid in a cool, dark place. Light and heat can break down the nicotine and affect the flavour of your vape juice. A cupboard or a drawer away from direct sunlight and heat sources is ideal.

Additionally, ensure that your e-liquid bottles are tightly sealed after each use to prevent air exposure, which can also lead to a decrease in nicotine potency and flavour quality.

Regularly check on your e-liquid to confirm it hasn't changed in colour, smell, or taste. Any significant changes might indicate that the e-liquid is past its prime.
