An advancement in the field of marijuana extracts involving the carbonation of the resin containing attributes new to the field of Cannabis extraction. This technique combines the carbonating effect of CO2, used as a cosolvent, in conjunction with a typical hydrocarbon butane extraction. This type of extraction, developed by Extractioneering, is called a "Cosolvent" extract. A vial of carbonated HTFSE created with the Cosolvent Cannabis extraction method that utilizes both CO2 and Butane as extraction solvents. Carbonation of the Cannabis extract makes for a more intense flavor and effect over traditional BHO and Live Rosin types. In addition, the carbonation preserves the product and allows it the opportunity to 'vintage' similar to wine, improving with age.
