HASH ROSIN
Hash rosin, whole melt Cannabis rosin (also known as marijuana rosin) uses a method of extraction that releases resin from several different forms of cannabis: dried flower, fresh plants, dry sift kief, and rosin made from hash, or rosin, is considered by many to be one of the purest forms of cannabis concentrate.

Rosin is made by combining high heat and immense pressure. Terpene and cannabinoid-rich oil (resin) is forced out of cannabis plant material called trichomes using a rosin press. When done correctly, rosin is highly potent and very rich in terpenes and cannabinoids.

HasH vs BHO, PHO, HHO
While Butane Hash Oil (BHO) is made by blasting cannabis with butane, propane, or hexane to release the trichomes, Rosin is extracted simply by applying heat and pressure to cannabis until the high-THC substance emerges.

BHO requires a much more complex process involving using chemical solvents and a closed-loop system that can be dangerous for your body. Rosin, it’s more natural and doesn’t contain any chemical solvents. Think in terms of food, you wouldn’t eat junk food daily, so why smoke it?
