Blasting is used to make concentrates by forcing a solvent through the plant material to extract its oils. Butane is one of the most common solvents used to detonate cannabis plant material. Blasting solvents can be dangerous due to flammable solvents, so be careful. Therefore, the cannabis packaging is done in a glass tube and the butane is forced through the end of the glass tube.
While blasting with solvents it can leave behind some residue in the concentrate, which can affect the taste of the cannabis concentrates and can also be breathed in when the product is smoked or vaporized. It is a common method used to create BHO and also used to make honey, wax, glass, honey toast and comb.
