Cannabis Control Testing Requirements for Cannabis and Cannabis Products


Cannabis “Phase 3” Testing Requirements Begin December 31st.  All cannabis harvested, and all cannabis products manufactured, on or after 12/31 must go through Phase 3 testing (in addition to the other requirements). See the requirements.


  • Cannabis and products cannot be transported to any retailer for sale
  • The lab may not re-test, and must issue a Certificate of Analysis (COA) based on the initial testing (initial COAs may not be amended)
  • Must quarantine the goods at the distribution site with a clearly identifiable batch number
  • Before attempting to remediate, a corrective action plan must be approved by the California Department of Public Health (CDPH); then, the remediated goods must be returned to the distribution center for testing before it is transported to retailers

It is also important to note that once a sample has been collected by the lab, the licensee may not cancel that test.
