It won’t be a surprise if you’re confused about the right CBD oil to buy when you visit your local vendors. There are three major spectra of CBD oil you’d often find: Full Spectrum, Broad Spectrum, and CBD Isolates.

For most people, they are all the same with different names. But in reality, they are worlds apart.

Full Spectrum differs greatly from Broad Spectrum, just the same way CBD Isolates is on a league of its own. However, what differentiates them is their constituent compounds such as cannabinoids and terpenes; and their percentage composition as you’ll learn shortly.

Before You Continue…

You already know that cannabis products with a high percentage concentration of CBD give a relaxing effect while a high percentage of THC gives a “high effect.” The spectrum of CBD oil is determined by the kind of cannabinoids that is present in it after extraction.

When combined with other phytochemicals, cannabinoids complement and amplify each other’s health benefits while mitigating the side effects. This is known as the “entourage effect.”

So, what is Full Spectrum CBD Oil?

Full-spectrum CBD oil contains all the phytochemicals that cannabis can offer such as cannabinoids, terpenes, CBD, and essential oils with only a minute THC composition below 0.3%.

Due to the low THC, it is not psychoactive. But all the phytochemicals work together to enhance the health benefits of all the cannabinoids. It is the most expensive of the three spectra of CBD oils, and it also gives the most relaxing effect.


  • Gives the most relaxing effect among other spectra
  • The least processed of all CBD oil spectra
  • Contains all cannabinoids, terpenes, and others; hence, better health benefits


  • Difficult to maintain a consistent percentage composition of the trace cannabinoids
  • Very expensive
  • Can give you a false positive in a drug test
  • Has the full aroma of cannabis which can attract so much attention to you

What is Broad Spectrum CBD Oil?

The broad-spectrum is just like the full spectrum except that it has zero traces of THC. It means the THC is completely removed. Nonetheless, the other phytochemicals present amplifies the therapeutic effects of each other to give similar entourage effects of the full spectrum.

It’s relatively cheap compared to Full Spectrum CBD oil and it’s more processed and readily available. But it doesn’t give as much relaxing effect as the full spectrum, and it’s perfect for those who are very sensitive to THC.


  • Less expensive than Full Spectrum
  • More processed than Full Spectrum
  • There is no risk of psychoactive effects
  • Gives the entourage effect


  • More expensive than CBD Isolates
  • Retains the flavor and aroma of cannabis

What is CBD Isolates?

CBD Isolates are the most common CBD oil for recreational and medical purposes. It is the purest of all spectra having 99% CBD by composition. Other trace cannabinoids, terpenes, and essential oils form only 1%.

Before2015, it was believed that CBD isolates give the most relaxing effect. But the ideology was debunked by a 2015 study by Lautenberg Center for General Immunology in Jerusalem.

It was concluded that although CBD isolates are pure in composition, they are not as effective as the full spectrum.

What gives the Full Spectrum the edge is the availability of several phytochemicals that gives rise to the entourage effect.


  • Can be used in most nations with strict cannabis laws
  • Popular for its relaxing effect
  • The least expensive of all spectra
  • Odorless and flavorless


  • Not as relaxing as the full spectrum
  • Doesn’t give the entourage effect
  • Great for people sensitive to THC


The beautiful thing about CBD oil is that none is inferior to the other. They are used according to the prevalent need, and people react differently to them. Getting accustomed to their differences and your unique metabolism will best inform your decision on the CBD oil to buy.
