Few cannabis extracts carry the historical significance and industry recognition associated with Rick Simpson Oil, commonly known as RSO. Emerging during a period when cannabis extraction techniques were far less sophisticated than they are today, RSO became widely recognized as a concentrated full extract cannabis oil produced through solvent based extraction methods. Unlike many modern cannabis products that prioritize cannabinoid isolation or highly refined formulations, RSO developed a reputation for preserving a broad range of compounds derived directly from the source plant material. This legacy has helped maintain its place as one of the most discussed extract categories within cannabis history.

Contemporary RSO formulations continue to reflect the philosophy of full plant extraction while benefiting from advancements in extraction safety, laboratory testing, and manufacturing standards. The category remains closely associated with full extract cannabis oil, concentrated cannabinoid formulations, and traditional extraction practices that emphasize plant preservation over molecular refinement. Producers such as Avexia, Dr. Solomon’s, Tikun Olam, Remedi, Encore, and various licensed cannabis manufacturers have contributed to the continued presence of RSO within regulated cannabis markets. As extraction technologies continue to evolve, Rick Simpson Oil remains an important reference point in the history of cannabis concentrates, illustrating how early extraction methods helped influence the development of today’s modern cannabis industry.
