Open Blasting

ˈō-pən blast-ing | Noun

A dangerous and unregulated method of extracting cannabis. Open blasting takes place within a glass or metal tube and is a solvent-based extraction performed without a closed-loop system. Due to the risk of explosion, open blasting is considered a potentially dangerous process and is not used in commercial extraction facilities.


I wouldn’t go for the open blasting method if I were you; I’d use a closed loop system instead.


They were lucky that there was no butane explosion after all that open blasting.
