WHAT IS RSO
RSO (Rick Simpson Oil) is a full-spectrum cannabis concentrate produced through ethanol extraction. Cannabis plant material is soaked in food-grade ethanol, the solvent dissolves the cannabinoids and terpenes, and the ethanol is evaporated off, leaving a thick, dark, full-spectrum oil.
RSO is associated with the medicinal cannabis movement — Rick Simpson, the namesake, popularized RSO as a cancer treatment protocol in the early 2000s. The medicinal claims are not FDA-evaluated, but RSO has a cult following in the medical-cannabis community.
RSO carts are 510 cartridges filled with diluted RSO oil. The oil is typically thicker than distillate or live resin, requiring specialized hardware (ceramic-core atomizers with larger wicking ports). RSO carts are common in medicinal markets and rarer in recreational/hemp markets.
WHO USES RSO CARTS
RSO carts are typically purchased by consumers seeking the full-spectrum cannabis experience for medicinal applications. The full-spectrum profile (cannabinoids, terpenes, flavonoids, and trace plant compounds) is preserved through ethanol extraction.
For recreational consumers, RSO carts are less common because the dark color and thick oil don’t match expectations set by clear distillate or live resin carts. The flavor profile is also less refined — RSO retains plant compounds that distillation removes.
