Moon rocks are made by taking a nugget of marijuana and dipping it in or spraying it with concentrate, or hash oil. They’re usually made with Girl Scout Cookies (the weed strain, not Thin Mints) flower and concentrate, but can be made with any strain.
The coated nugget is then rolled in kief. Kief, also called pollen or dry sift, is the sticky crystals that cover the cannabis flower. This crystal residue contains terpenes and cannabinoids. You can smoke moon rocks like you would any other nug, by breaking it up into a joint, bowl, vape, or pipe. Keeping it lit isn’t easy, and it’s also super dense and greasy, so glassware like a bong or pipe is the preferred way.
