BHO
From Wiki Weed
BHO stands for butane hash oil and is a potent concentrate of cannabinoids made by dissolving marijuana in its plant form in a solvent (usually butane). The resulting product has very high THC levels (generally more than flowers or hashish) and is a thick, sticky oil. BHO is also referred to as honey oil, "dabs" or "dabbing," earwax, or shatter, depending on the manufacturing method.
