Solventless

Solvent free refers to cannabis concentrates and extracts that originally relied on the use of solvents like butane or propane during processing, but have been carefully purged and evaporated down to undetectable residual levels through proper post-extraction techniques. Some preferred extraction methods rely on solvents like butane to efficiently strip essential cannabis compounds like THC, CBD and terpenes away from plant material. However, allowing residual traces of these chemical solvents to linger in the final concentrate or extract can prove harmful if ingested. Requiring third party lab testing to confirm concentrate products are completely solvent free gives consumers crucial peace of mind regarding their safety and purity. Responsible manufacturers purge all extracts until completely solvent free before allowing any products to go to market.
