Labeling & Testing for Medical Cannabis

Hawaii's laws may not be perfect...after all, what state has perfect laws???  However, it is good to know that they acknowledge those gray areas and are working to address them.  According to Hawaii News Now, the state has established the working group that was required in Act 116 (the most recent update to Hawaii's medical cannabis laws).  The purpose of this working group is to evaluate employment issues related to medical marijuana patients and evaluate the manufacture and sale of edibles.

Also under Act 116, the state now allows for products to be retested if a sample fails.  This is good for a couple of reasons.  First, many states are dealing with the fallout of stricter rules related to testing.  Some of the processors that are falling victim to this feel like the testing isn't valid because they have never had product issues before.  Retesting will allow processors to confirm or deny those initial results.  Second, labs aren't perfect.  They can make mistakes too.  Therefore, it's important to be able to have the same lab run another test or check those initial results against those from another lab.

Here's the lay of the land as it stands today with regards to labeling and testing:

What is on the label?

  • Net weight of product
  • Concentration of THC, THCA, and CBD
  • Dispensary license # and name of production center
  • Batch # and date of packaging
  • Unique identifier barcode
  • Date of harvest or manufacturing
  • Use by date
  • Instructions for use
  • Warnings
  • Chemical disclosure (defining chemicals used in manufacturing)
  • Name of test lab

How is product quality ensured?

  • Every batch is tested for cannabinoid profile (THC, THCA, CBD, CBDA, CBG, & CBN), heavy metals, solvents, pesticides, moisture content, microbials, mold and other foreign materials
  • Batches are destroyed if testing fails
  • State performs periodic planned and unplanned inspections


  • State has established acceptance limits for contaminants
  • Significant oversight and control of labeling and testing
  • Lab must be certified and accredited to ISO 17025 or equivalent


  • Full cannabinoid and terpenoid profiles are not required on the label
  • Tepernes are not required to be tested
  • Use by date is not required to be supported by testing
