VERMONT MEDICAL CANNABIS ONLY Mellow Mints 400mg Dark Chocolate (RSO/FECO) 5 x 80mg per package RSO (Rick Simpson Oil) and FECO (Full Extract Cannabis Oil) are potent, dark, tar-like cannabis oils made to be ingested, offering full-spectrum effects for medical use, with the main difference being the extraction solvent: RSO often uses alcohol (like isopropyl), while FECO uses grain alcohol or ethanol, retaining more terpenes; both are very strong, requiring small doses (rice-grain size)
