FECO stands for Full-Spectrum Extract Cannabis Oil. Full-spectrum means that all the cannabinoids and terpenes found in the cannabis plant are extracted at the same ratios they were at in flower form. This leads to a more whole-flower experience, complete with the entourage effect, which is when cannabinoids work together synergistically leading to more potentially beneficial effects. FECO is extracted utilizing ethanol or CO2 as a solvent. Through the use of this process, more of the cannabinoids are retained in the remaining resin extract.

FECO is a dark, thick oil that usually comes packaged in a syringe for easier dosing. It is generally ingested, meaning it is consumed orally and processed by the liver like an edible. Although, it can also be applied topically to the skin. FECO has a strong herbal cannabis flavor that may taste unpleasant but can be covered with food or placed in a gel capsule to avoid tasting the substance. If the flavor doesn’t bother you, the oil can be taken directly by mouth.

Due to its high potency, begin with a very small dose, no larger than a grain of rice. Because FECO is consumed orally, onset of effects can take over an hour. So if you don’t feel anything at first, wait 2-3 hours before taking a small dose again. Edible effects can last 8-12 hours and produce a more intense “high” than inhaled consumption methods, so it can even be better to wait and try again the next day to avoid any unpleasant overconsumption.

Patients consume FECO to help with a range of problems, especially pain relief and reducing inflammation.
