California Cannabis Track-and-Trace System

Tracking Cannabis Through the Supply Chain:

All licensees operating in the commercial cannabis market must participate in tracking cannabis as it moves through the supply chain - from seed to sale. California's Track-and-Trace system launched in January 2018, and businesses receive credentials and access as they are issued annual or provisional licenses.

Cannabis manufacturers are required to track the movement of cannabis as it is transferred between licensees and, for vertically-integrated businesses, between license types. Until receiving Track-and-Trace credentials, this movement can be tracked using sales receipts, like the sample listed below.

  • Sample Sales Receipt (PDF) – for documenting transfers of cannabis and cannabis products before becoming credentialed and gaining access to Track-and-Trace.
