THC remediation

THC remediation is any processing step intended to reduce the delta-9 THC concentration of a hemp extract, typically to bring it within legal or product specifications.

Methods include preparative chromatography, which separates THC from other cannabinoids by passing the extract through a column, and chemical conversion that changes THC into other compounds. Remediation is used to keep extracts below the federal hemp limit and to produce broad-spectrum products that retain other cannabinoids while targeting 0.0% THC. Each pass can also remove or alter minor cannabinoids and terpenes.

Because remediation is a process rather than a result, it must be verified by testing, and the certificate of analysis for the finished batch is what shows the outcome. A reader looking at a remediated product should check the total THC figure against the method's reporting limit, and may also notice a different minor cannabinoid profile than in a full-spectrum extract. Some conversion methods can leave behind by-products, which is another reason a complete certificate matters.
