Researchers at Colorado State University Pueblo have developed a rapid vegetation identification technique for onsite use. The method uses a molecular tag that produces a visible color change to distinguish between different cannabis types. It enables quick, field-based decisions with optional lab confirmation for added accuracy. The technology supports compliance, traceability, and enforcement across regulated markets.
Reliable product traceability is critical in agriculture and regulated industries. Current systems, such as RFID tracking, can be altered or tampered with, creating risks in supply chains. This is especially important in cannabis, where hemp and marijuana have different legal and regulatory requirements. Misidentification can lead to legal penalties, including fines and jail time. A fast, tamper-resistant identification method helps reduce these risks and improves trust in the system.
This innovation uses a molecular tagging system that reacts with specific compounds in plant material. When tested, the tag produces a color change that signals a yes-or-no result for identification in the field. The test can be performed using an antibody assay or an enzymatic reaction, making it simple and portable. For added certainty, samples can be analyzed in a lab where the molecular tag acts like a chemical barcode, storing detailed information about the product. Stable isotope labeling can also be used to trace the geographic or production origin of the material.
