Dabs are concentrated doses of cannabis that are made by extracting THC and other cannabinoids using a solvent like butane or carbon dioxide, resulting in sticky oils also commonly referred to as wax, shatter, budder, and butane hash oil (BHO). While it’s possible to extract non-psychoactive compounds like CBD, THC is what’s behind the potent effects of dabs, making them the fastest and most efficient way to get really, really medicated. Terpenes, or the aromatic oils that give cannabis flavor, can also be extracted, although it can be difficult to preserve these volatile compounds in the extraction process.
