CBD in vape oil and E-juices: Isolate, oil or something else? The source of CBD in your vape liquid.
CBD oil- While there are many different varieties of hemp CBD oils as described HERE , all CBD oils have some general things that are the same. Hemp CBD oil is generally going to be around 5% - 50% CBD by volume and will contain the CBD molecule as well as other molecules like THC, CBN, CBC and other things such as naturally occurring terpenes, chlorophyll, lipids and other naturally occurring plant constituents. It has been argued that CBD in this form is less "bio available" to your body, basically meaning your body cant use the CBD in the oil efficiently and the CBD is not reaching its full potential when ingested in this manner. While its generally regarded as being true that no one really knows how big or small of a roll this plays in how well the CBD actually works. On the other hand it has also been said by some that you want the CBD oil in this form as it can provide all the other chemicals your body needs besides just CBD.
CBD isolate- Commonly referred to as "CBD crystals" is generally between 95%-99.99% CBD. This CBD form is not an oil, but is typically a white or off white crystalline powder. As the name suggests, this form of CBD is NOT soluble in water much like its counterpart, CBD oil. Because CBD isolates are not water soluble they cant be mixed with most vape oil "bases" but can be mixed with propylene glycol which is generally easier than the CBD oil itself. Another benefit to using CBD isolates is it contains nearly no taste and so the vape oils can be flavored easier and generally will not separate as easily as CBD oil. One of the biggest things you will hear is that CBD isolates, since they are very pure and can be very small is size, are actually received by your body better and therefore more bio-available, making for a more effective source of CBD than CBD oil itself. One concern when using CBD isolate is that because it is so pure, it actually does not contain any of the other chemicals that might be helpful for your body.
Water Soluble CBD oil powder- So this is a new commodity that just recently was introduced into the market. This used to only be available to wholesale buyers but DiscoverCBD.com just made it available to all customers real recently. All water soluble CBD oil powders will contain CBD oil and "binders" or they "nanosize" the CBD and encapsulate it to make it water soluble. These are great to use when making E-liquids because they will dissolve in vegetable glycerin with no additional emulsifiers. These powders can be used for many other things as well such as CBD drinks, tinctures and more. Please note that not all water soluble CBD oil powders are created equal and while many will claim to have water soluble CBD powder very few actually are. If you plan on making your own CBD oil with water soluble powder you will need an industrial homogenizer to mix it. In addition to there being a lot of fakes out there the nano CBD that is water soluble is typically very diluted and not very high in mgs of CBD/volume. You also want to stay away from turmeric based water soluble products if you are making E-liquids or any vape product because turmeric does not vape and instead will just burn and taste awful.

Vape oil/E-juice bases
PEG- (Polyethylene Glycol) PEG as well as polypropylene glycol are generally regarded as some of the first bases used for E-Juices. PEG while it has its limitations is generally regarded as a great emulsifier making mixing E-Juices using PEG easy. PEG also vaporizes quite well and will produce a smooth vapor cloud allbeit generally smaller than some of the other bases available. While PEG has seen a smaller portion of the E-juice market than it used to, it's still very widely used and you will commonly see it mixed with VG or PG. PEG is defined by Wikipedia as having a low toxicity. https://en.wikipedia.org/wiki/Polyethylene_glycol
PG- (Propylene Glycol) PG is much like PEG but generally thinner. PG generally does not emulsify CBD oil quite as good as most PEG its still generally regarded as a good emulsifier. PG just like PEG doesn't create huge vape clouds however it does vape cleanly and is smooth on inhale. PG is widely used in vape oils both for CBD and in the tobacco industry. PG is defined by Wikipedia as having a very low toxicity. PG is used in many items you use in your everyday life such as in ice cream, toothpastes and lotions. https://en.wikipedia.org/wiki/Propylene_glycol
VG- (Vegetable Glycerin) VG has become very popular to use in E-juices. Generally regarded as one of the best "bases" for E-juices since it produces large vapor clouds and has been deemed as safe to vaporize. VG has its downsides however, the first one being that its ability to dissolve additives and its ability to emulsify CBD oil is limited. You will commonly see companies adding emulsifiers to VG based E-liquids because VG in and of itself will rarely mix well with oil based concentrates.
Coconut oil- Refined coconut oil is a relatively new addition to the vape oil scene. Coconut oil is actually relatively good at mixing with CBD oils. While the use of Refined coconut oil is relatively new and the information available is limited there are a few things we do know about using it as a base for E-juices. We have noticed that coconut oil has a harder time getting wicked up into the atomizers of most vape pens. This difficulty being wicked means that it has the ability to run dry and takes a while to "soak" before it can be vaped in most pens. There are also reports that it can leave a bad residual taste in your mouth after exhale. While there are a few negative reports of using coconut oil as a base, it is quickly gaining popularity in the vape community and some seem to really like coconut oil based oils. READ MORE
