With our full-spectrum CBD hemp oil, you get all of the plant’s fatty acids, terpenes, and amino acids. The other key components of CBDfx vape oil additives are common food-grade ingredients propylene glycol and vegetable glycerin, which work together to provide you with a consistent and satisfying puff of vapor.

HOW DO I USE IT? Follow the label instructions. CBD vape oil additive 300mg gives you a highly concentrated serving of CBD and has a strong herbal flavor.

What are the differences between CBD oil, CBD vape juice, and CBD additives?

The terminology about CBD can be confusing for consumers, especially because many brands don’t label their products clearly. But it is worth your time to understand the fine distinctions so you get exactly what you’re looking for.

With CBDfx, all of these CBD-infused liquids start with full- or broad-spectrum hemp oil, which includes important active components such as terpenes and amino acids. The differences in CBD oil, vape juices, and additives come when the oil is mixed with other ingredients to change the way the product interacts with your body. To make CBD oil tincture, which you take orally via a few drops under your tongue or by adding it to food or a drink, CBDfx blends the hemp oil with MCT (medium-chain triglyceride) oil, which is composed of fatty acids that help your body quickly and easily absorb the CBD. 

CBD vape juices are formulated for use in standard vape kits. To ensure that the CBD heats up and vaporizes properly, the oil is mixed with propylene glycol and vegetable glycerin, two natural ingredients that are commonly used in vape liquids (often referred to as e-juice). CBD vape juices also typically come with flavorings that give the user a taste of fruit or other sweets while they puff.

CBDfx vape oil additives also feature full-spectrum CBD hemp oil blended with propylene glycol and vegetable glycerin. The additives, however, are designed to be used along with any e-juice, so you can get the experience of CBD while you still enjoy your favorite brands and flavors of e-juice. You simply add half a dropper or more of CBD vape oil additive to your vaporizer’s liquid tank. This approach lets you craft the perfect blend of e-juice and CBD oil for your tastes and needs.

By the way, CBDfx vape oil additives have just three components—CBD hemp oil, propylene glycol, and vegetable glycerin—and they are all food-grade ingredients, so you can take them orally, just as you would a tincture.

Can the additive be vaped or taken sublingually?

The quick answer to this question is both. The only ingredients in our CBD vape oil additive 300mg  are CBD hemp oil, propylene glycol, and vegetable glycerin. The latter two are included to ensure that the oil vaporizes cleanly and puffs smoothly. But they are food-grade ingredients, so they’re safe enough to allow you to take the oil as a tincture with a few drops under your tongue or in your food or drink.  

Are 300mg of CBD oil in the additive?

CBDfx vape oil additive comes with a full 300mg of full-spectrum CBD in the 10ml bottle. CBDfx does not recommend specific amounts for our customers to enjoy per use. However, we have noticed that the average length of time one bottle lasts a customer is around a month.

Can I add the CBD vape oil additive 300mg to my own vape pen?

That’s exactly what it was designed for! Besides the full-spectrum CBD oil, the additive has only two other simple components—propylene glycol and vegetable glycerin. Those ingredients are commonly used in many brands of e-juice because they help the liquid to vaporize efficiently and puff smoothly.

You can add a few drops of CBD vape oil additive 300mg to the e-juice tank of any vape pen or rig.
