Broad-spectrum is a formulation term describing an extract that preserves a range of the plant's naturally occurring compounds while deliberately removing one or more specific cannabinoids, most commonly tetrahydrocannabinol. The result sits compositionally between a full-spectrum extract and a single-compound isolate.
This category exists largely because of the chemical and regulatory significance of THC. Removing it allows a preparation to retain other cannabinoids and terpenes while altering its classification under controlled-substance frameworks.
As with other formulation terms, broad-spectrum describes the composition of a substance rather than implying any particular outcome from its use.
