"Treating a cannabis plant with dry ice is a method used to extract trichomes, which contain cannabinoids like THC and CBD, from the plant material. This process is commonly known as dry ice hash extraction or dry ice kief extraction.
The trichomes are the resin glands on the surface of the cannabis plant where cannabinoids, terpenes, and other compounds are produced. By using dry ice, which is solid carbon dioxide (CO2) at a very low temperature (-78.5 degrees Celsius or -109.3 degrees Fahrenheit), the trichomes become brittle and can be easily separated from the plant material."
