This Deep Dive serves as a summary of a 2022 detailed study about the chemical characteristics and safety profiles of the major extraction techniques employed in the cannabis and hemp industries. It teaches students about the various technologies and technical approaches behind the creation of cannabis extracts and concentrates.
A January 2022 research study entitled "A Comprehensive Review on the Techniques for Extraction of Bioactive Compounds from Medicinal Cannabis" that was published in the journal Molecules investigated and summarized the most common cannabis extraction methods.
"We comprehensively analysed the current literature and drew a critical summary of the extraction methods implemented thus far to recover bioactive compounds from medicinal cannabis," reported the study. It also discussed "critical factors affecting extraction yields" and proposed considerations for future extraction methodologies.
