Yes, residual solvents are possible with the THC extraction process. I prefer to use THC concentrates extracted with CO2 to avoid inhaling residual solvents.

- robocat 7y agoCan you tell only CO2 was used?
- whenchamenia 7y agoCo2 iirc is a physical extraction, like bubble hash, while this is concerning solvent hash, a different product. The correct way to extract solvents is under vacuum.
- ficklepickle 7y agoSupercritical CO2 is a (very non-polar) solvent. I can't imagine what would make that a physical or mechanical extraction. Good CO2 extraction uses two passes at different pressures. One to extract the terpenes and one for the cannibinoids.
