Residual Solvents

Overview

Concentrated cannabis products made using a solvent must be purged at the end of the extraction process. Trace amounts of the solvent used can remain even after purging, and high concentrations of certain solvents can be harmful if consumed. Screening for residual solvents is applicable only for cannabis products made using a solvent-based extraction method.
