2018-20 Total delta-9 THC Results from Regulatory Hemp Samples​

The table of 2018-20 total delta-9 THC regulatory results lists the anonymized results of regulatory hemp samples that DATCP tested from 2018 to 2020. 

For any given variety name, past performance does not predict future performance of that variety name in regulatory tests. 

  • The information in this table does not imply endorsement and is provided strictly as a resource for growers to consider in their evaluation of potential hemp variety names.

  • Hemp lots were sampled and then tested for total delta-9 tetrahydrocannabinol (total delta-9 THC). One hemp lot was one variety planted in one contiguous growing location. A lot was required to have a total delta-9 THC content of 0.3% or below in order to be issued a fit for commence certificate.

  • The variety names listed on this table are based on grower self-reporting. Inconsistent variety naming conventions used by growers may impact the accuracy of the variety information included in this table.

  • Regulatory samples that share the same variety name, as identified by the grower, may not actually represent the same variety.

  • This table includes only variety names reported as being planted in more than 5 lots.

  • This information in this table does not control for the plant development stage at the time of regulatory sampling.​
