Extraction lets you make your own concentrates for dabbing. We usually refer to concentrates as rosin, oil, wax, BHO (Butane Honey Oil), shatter, and budder. They vary in texture and flavor and are made with different extraction techniques, like rosin pressing using pressure, heat, and time, and BHO extraction with an extractor and butane or DME. Which method to use, usually comes down to your own preference and what you enjoy smoking or vaping.
