Broad-spectrum CBD contains cannabidiol and all the other compounds within the plant, save for THC, which is completely removed after the initial extraction.
In a very simplified manner, broad-spectrum CBD is like a mix between full-spectrum CBD and CBD isolate. It contains the entire spectrum of cannabinoids in hemp except for the THC part.
If a CBD extract is full spectrum, this means it contains all compounds naturally found in the hemp plant, including traces of THC (under 0.3%).
Although non-psychoactive, full-spectrum CBD differs from broad spectrum because it contains those low levels of THC. As such, taking full spectrum CBD can give you a false positive during a drug test, especially if you consume high doses of CBD oil daily.
Cannabidiol (CBD) isolate is a pure form of extract that “isolates” CBD from the hemp plant. This extraction process removes all color, flavor and the trace amounts of THC, which makes it a great extract for targeting just the CBD compound.
