Modern cannabis extraction utilizes a range of solvents and techniques to isolate desirable compounds from plant matter.
One common category is hydrocarbon extraction, using compounds like butane and propane.
When performed correctly, hydrocarbon extraction efficiently produces quality extracts. However, safety risks also exist if not handled properly.
What is Hydrocarbon Extraction?
Cannabis components are extracted using hydrocarbon solvents such as butane, propane, hexane, or isopropyl alcohol.
Trichomes and essential oils are dissolved by running solvent through plant material in a closed system.
The solution then passes through a vacuum oven, where heat and low pressure cause the solvent to evaporate, leaving behind the cannabinoid and terpene extract.
Hydrocarbons like butane are efficient at pulling key constituents from cannabis while being easy to purge from the final product.
Properly purged extracts are safe for consumption.
