Cannabidiol (CBD) is one of the key non-psychoactive compounds found in the cannabis plant, highly regarded for delivering wellness benefits without the “high” that comes with THC. But not all CBD is created equal. There are full spectrum, broad spectrum, and isolate CBD, and the type used in a product can shape how the product works and what you can expect from it.
What Is Full Spectrum CBD?
Full spectrum CBD is a cannabis extract that retains the full range of naturally occurring compounds found in the hemp plant. That includes CBD, of course, but also other cannabinoids like CBN, CBG, and CBC, along with terpenes and trace amounts of THC.
That trace amount of THC is what sets full-spectrum CBD apart from its broad-spectrum counterpart. Under federal hemp regulations, full spectrum CBD products must contain no more than 0.3% THC by dry weight—far too little to produce a noticeable high, but enough to round out the cannabinoid profile.
Full Spectrum vs Broad Spectrum vs CBD Isolate
These are the three types of CBD oil and the three terms that get mixed up a lot, so here’s a quick comparison.
| Full Spectrum CBD | Broad Spectrum CBD | CBD Isolate | |
| THC content | Trace amounts (under 0.3%) | None (removed during processing) | None |
| Other cannabinoids | Full range (CBN, CBG, CBC, etc.) | Full range, minus THC | None |
| Terpenes | Yes | Yes | No |
| Entourage effect | Strongest | Present, but without THC’s contribution | Not applicable |
| Best for | Those who want the most complete hemp profile and are not concerned about trace THC | Those who want multiple cannabinoids but need to avoid THC entirely | Those who want CBD only, with zero other compounds |
| Typical form | Tinctures, CBD gummies, topicals | Tinctures, CBD gummies, topicals | Powders, tinctures |
Each has its place depending on your goals and any sensitivities you may have to THC, even in trace amounts.
What Is the Entourage Effect?
The main reason people seek out full spectrum CBD is something called the “entourage effect,” which is the theory that cannabinoids and terpenes work better together than any single compound does on its own. Instead of CBD acting in isolation, it interacts with companions like CBG, CBN, THC, and various terpenes, potentially offering a more well-rounded experience.
While research into the entourage effect is still evolving, many people who try full spectrum products report a more noticeable or “fuller” effect compared to isolate-based alternatives, which is why full spectrum formulas have become a favorite among CBD enthusiasts.
What to Check Before Buying Full Spectrum CBD Oil
Not all full spectrum CBD products have the same potency and purity. A 2021 Leafreport research found 25% of CBD products are not tested for purity. Here’s what separates a high-quality product from a questionable one:
- Third-party lab testing: Reputable brands publish a Certificate of Analysis (COA) with a breakdown of cannabinoid content and a confirmation that THC levels are within the legal 0.3% threshold.
- Source of the plant: Hemp grown in the U.S. under regulated agricultural programs tends to have more consistent quality control.
- Extraction method: CO2 extraction is widely considered the cleanest method, avoiding residual solvents.
- Transparent labelling: Look for clear milligram dosing per serving, not vague claims.
Is Full Spectrum CBD Legal?
Yes. Hemp-derived full spectrum CBD products containing less than 0.3% THC are federally legal in the United States under the 2018 Farm Bill, though state laws can vary. In California and other states with regulated adult-use cannabis markets, you’ll find full-spectrum CBD products sold through licensed dispensaries, like The Artist Tree, often alongside higher-THC cannabis products, with the added benefit of lab testing required under state regulation.
