CBD E Liquid Calculator

Several customers have already told us about the benefits they’ve experienced from using/vaping CBD with a CBD vape pen. Benefits such as relieving muscular and joint pains, and have not experienced any of the psychoactive effects caused by tetrahydrocannabinol (THC), which are found in the cannabis plant. For more information, we recommend you read our guide on how CBD can help you.

Since their release earlier this year (2018), the pre-mixed CBD e liquids have already proven very popular, but a lot of people are interested in infusing their favourite e liquid flavour with CBD oil. CBD booster shots are far more powerful than the pre-mixed CBD e liquids, so it’s good to know exactly how much you should add to your e juice.

Using our easy to use CBD e-liquid calculator, you’ll be able to find out exactly how much CBD you will need add to you tank, or to vape neat, to get your desired daily in-take!

Deciding your CBD dosage

First, you should decide on your daily CBD dosage:

  • 5-10mg of CBD per day for mild symptoms
  • 30mg per day for medium symptoms
  • 50mg per day for stronger symptoms.

Users can experiment with their desired dosage depending on their level of pain.

CBD and E Liquid Measurements

Here are two examples of how to mix your desire dose of CBD oil with your e liquid using a 2ml tank:

If you are using the 500mg 10ml CBD Booster Shot by MIST: to achieve a dosage of 10mg of CBD oil a day, you will need to add 0.2ml of the booster shot to your tank, filling up the rest with your favourite e liquid flavour.

The entire 10ml of the booster shot contains 500mg of CBD oil. A single millilitre of the booster shot will contain a tenth of the entire amount of CBD oil, which is equal to 50mg. If your desired daily dosage is 10mg a day, you will need to split 1ml into fifths, which equals 0.2ml. There are around 20 drops in 1ml, so when needing a fifth of 1ml, you will split those 20 drops into fifths and use 4 drops.

If you are using Harmony’s CBD Pure Base booster shot: this is a slightly milder booster, with a CBD content of 300mg. This means that you will need to use slightly more than you would with the MIST booster shot. 1ml of the Harmony Pure Base contains 30mg of CBD oil, so you will need a third of that, or 0.33ml, which equates to around 6 drops of Pure Base. These drops can be added to the rest of the juice in your 2ml tank.

We appreciate that the mathematical process of adding CBD oil to your e liquid may seem like a bit of a hassle, so we decided to create this easy-to-use CBD Calculator. Using our CBD calculator will allow you to accurately determine how many drops of a single CBD booster shot you will need to reach your desired dosage.

In summary:

4 drops of MIST 500mg CBD Booster Shot in a full tank of e liquid = 2ml 10mg CBD e liquid.

6-7 drops of Harmony 300mg CBD Pure Base in a full tank of e liquid = 2ml 10mg CBD e liquid.
