How THC is Removed from CBD Oil

Using hemp oil as a health supplement can be quite appealing. For some, however, there’s the issue of tetrahydrocannabinol, or THC—the cannabinoid responsible for marijuana’s psychoactive effects. By law, CBD products must contain less than 0.3% THC, which is not enough to have an affect on CBD users. However, whether it's drug testing or other concerns, many people interested in CBD are still worried about THC being in their system. These CBD consumers prefer what's called Broad Spectrum CBD, which contains no detectable level of THC. To prepare Broad Spectrum CBD, manufacturers must employ a variety of processing methods to extract the cannabinoids from the hemp plant and then remove the remaining THC.

how to remove thc

CO2 Extraction Method
The CO2 extraction method is arguably the most popular among hemp oil manufacturers because it allows them to remove unwanted substances while retaining beneficial ones like terpenes and cannabinoids. It works by using carbon dioxide (CO2) as a solvent to separate desired compounds from plant material. The process involves three steps: first, pressurized CO2 is applied to plant matter; second, this mixture is passed through an evaporator to separate the CO2 from the desired compounds; and third, heat and pressure are applied to further refine the extract and remove any trace amounts of THC present in it. As an added bonus, this method also helps preserve natural flavors from the plant material.

Distillation Process
Distillation is another popular method for extracting cannabinoids out of the hemp plant—and for good reason. This process takes advantage of each compound’s unique boiling point so that unwanted substances can be removed without damaging beneficial molecules such as cannabinoids and terpenes. The distillation process involves heating up hemp extract in order to vaporize its components; then collecting those vapors in a chamber where they condense back into liquid form; then separating out unwanted substances like waxes, lipids, and chlorophyll; finally cooling down the remaining liquid so that it can be safely consumed by users.

Chromatography Method
Chromatography can be used to remove THC from hemp oil extracts without compromising their quality or potency. Chromatography is used on the extract obtained by other techniques. This method makes use of columns filled with adsorbent materials like activated charcoal or silica gel which retain some compounds and do not retain others. In this case, manufacturers use chromatography columns specifically designed to separate THC molecules from CBD and other cannabinoids. This ensures that only clean extracts, free from any psychoactive substances, make it into final products for consumers' peace of mind.
