Glossary

Full spectrum

An extract retaining the plant's full range of cannabinoids and terpenes, including THC.

Full-spectrum products are marketed on the entourage effect. Since that effect is unproven in humans, the honest framing is that full-spectrum products contain more compounds — not that they are demonstrably more effective.

Full spectrum contains THC. If you are drug tested, this matters.

Also written as: full-spectrum, whole plant.
