Rosin made from hash, or hash rosin, is considered by many to be one of the purest forms of cannabis concentrate. Cannabis 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. GMO Cookies, also known as as "GMO Garlic Cookies" and "Garlic Cookies," is a potent indica-dominant hybrid marijuana strain made by crossing Girl Scout Cookies with Chemdawg. This strain produces a euphoric high with mentally uplifting effects.
