Fact Checked by Doctor NameOpen blasting refers to the dangerous practice of using solvents like butane or propane to extract cannabis concentrates without a closed-loop system.
This guide will examine what open blasting is, why it’s so hazardous, and safer extraction alternatives.
What is Open Blasting?
Table of Contents
Open blasting uses volatile solvents to strip cannabis plants of their coveted resins and essential oils.
The solvents dissolve the sticky oils, allowing them to be separated from the plant material.
After filtering out the plant particles, the solvent is then evaporated, leaving behind a concentrated cannabis extract.
The problem is open blasting takes place openly in the air instead of inside professional-grade closed-loop extraction machines.
Open blasting provides no control over the flammable solvent vapors that are released. This creates an extremely high risk of combustion and explosion.
The uncontained vapors can easily be ignited by something as small as a refrigerator magnet or phone, leading to serious bodily harm.
Safer Extraction Methods
Closed-loop extraction systems allow safe, regulated, solvent-based cannabis extractions. They fully contain the solvents, avoiding any exposure to spark hazards.
Closed-loop systems use vacuum chambers that safely recover the solvents after extraction for reuse or proper disposal. This eliminates the release of harmful vapors into the environment.
Solventless extraction methods like ice water hash or rosin pressing avoid the risks of volatile solvents altogether.
While the yields may be lower, these techniques extract cannabis concentrates using only ice, water filters, heat, and pressure.
When performed safely, solventless extractions provide clean, potent concentrates without endangering the operators.
In summary, open-blasting cannabis should be avoided due to the substantial threats it poses.
Instead, invest in professional closed-loop systems or utilize safer solventless methods to produce marijuana concentrates responsibly.
