Cannabis as a plant has a documented history of human use for over 10,000 years. Originating in Central and possibly Southeast Asia, its been introduced and successfully cultivated on every continent except Antarctica. Typically consumed orally or through smoking the harvested flower, another popular way of consumption is through extracts.
Extracts of the cannabis plant have a similarly-storied history. Located on the exterior of the flowers, the trichomes of the cannabis plant produce and store the cannabinoids and terpenes responsible for both the aroma and effects of the plant. Originally, these trichomes were collected and compressed intro blocks known as “hash” or “hashish” for smoking. While still popular, especially in European markets, most cannabis extracts now take the form of a “hash oil,” that is to say, a concentrated resin of the cannabis plant. Hash oil may be consumed via a technique called “dabbing.”
To dab, one simply heats a specially-designed glass piece (known as a “banger”) with a butane torch, blowtorch or "crème brulee" torch, reaching a temperature around 500-600 degrees, before dropping the “dab” into the banger. If heated properly, the hash oil will completely vaporize, allowing for the absorption of the cannabinoids and terpenes without the carcinogenic byproducts of combustion!
