Open blasting

Open blasting is an archaic, unsafe method of extracting cannabis concentrates that involves using volatile chemical solvents like butane or propane openly in an unsealed environment, rather than within the confines of a professional closed loop system as is the standard today. Open blasting fails to contain flammable solvent fumes, allowing their unrestrained release into surrounding areas, creating an extremely dangerous fire and explosion hazard. Open blasting may also result in contaminants or residuals remaining in the final product after improper purging. Due to egregious risks to consumer safety and property, open blasting has been universally banned under all legal regulatory cannabis frameworks. Today’s professional closed loop extraction systems allow licensed producers to safely extract clean, potent concentrates. Advanced equipment also recovers used solvents instead of venting them freely into the atmosphere, benefitting the environment.
