Solvents such as butane, propane, ethanol, or CO2 are commonly used to extract cannabinoids and terpenes from the cannabis plant to create concentrates like shatter, wax, and oils. If not properly purged, small amounts of these solvents can remain in the product, posing potential health risks to consumers.

A proper vacuum purge eliminates residual solvent. Seeing anything above 500 PPM on a COA is a concern.
