Seed-to-Sale Tracking
Last reviewed · By Chad Griffith
Seed-to-sale tracking is the cannabis industry term for the comprehensive surveillance of every cannabis plant and product from initial planting through final sale to a consumer or patient. State Cannabis Regulatory Authorities require seed-to-sale tracking through state-mandated systems — most commonly METRC (operating in approximately 20 states), with BioTrack THC and state-built systems used in other markets. Every plant receives an RFID tag at the immature plant stage. Every harvest receives a batch ID. Every package receives a unique METRC tag. Every transfer, conversion, sample, sale, and disposal is reported. The system creates an audit trail intended to prevent diversion to the illicit market.
Frequently Asked Questions
What systems are used for seed-to-sale tracking?
METRC (Marijuana Enforcement Tracking Reporting Compliance) is the dominant system, mandated in California, Colorado, Maine, Maryland, Massachusetts, Michigan, Missouri, Montana, Nevada, Ohio, Oregon, and others. BioTrack THC operates in select states. Some states (New York, Connecticut) operate state-built systems. New Jersey operates METRC; New York's state-built system has been gradually transitioning. Always verify the current system on the state CRA website.
What events must be reported in seed-to-sale tracking?
Required reportable events typically include: planting an immature plant in a vegetation room, transitioning to flowering, harvesting (drying weight), packaging into batches, lab sample creation and submission, lab result receipt, package transfers between licensees (with manifest), package conversions (e.g., flower to extract), package destruction (waste log), retail sale to consumer or patient. Reporting deadlines vary — typically 24 hours, sometimes immediately.
What happens if seed-to-sale records are inaccurate?
State CRAs use the tracking system as the primary source of truth during audits. Discrepancies between physical inventory and tracked records can trigger: warning letters, civil penalties (often $1,000-$25,000 per violation), suspension of license operations pending reconciliation, or revocation for repeated/willful violations. Many states require licensees to maintain written reconciliation logs documenting any corrections to tracking system data.
Who has access to seed-to-sale data?
State regulators have full real-time access. Licensees see only their own data. METRC also makes aggregate market data available to states and (in limited form) to the public. Consumer-facing transparency varies by state — some states require COA QR codes on packaging that link to lab results pulled from the tracking system.
