A method of extracting and decarboxylating cannabinoids from cannabis, the method comprising:
- (i) extracting cannabinoids by contacting the cannabis with a solvent, thereby forming a cannabis extract,
- (ii) decarboxylating the cannabinoids in the cannabis extract by subjecting the cannabis extract to microwaves at a temperature of about 100° C.-200° C. in a sealed container for a time period sufficient to form the corresponding decarboxylated cannabinoids in the cannabis extract, and
- (iii) removing the solvent from the cannabis extract, thereby producing a cannabis resin;
- wherein the decarboxylated cannabinoids in the cannabis resin are then subjected to winterization, and wherein the solvent is selected from the group consisting of 80%-100% ethanol, ethylene glycol, isopropanol, and combinations thereof.
