Invitation to Discussion on Evaluating THC compounds: What is and is not “impairing”?

April 27 session continues focus on Delta 8 and other unregulated cannabinoids

The public and the cannabis industry are invited to an April 27, 2022 discussion to help shape future policy and rules related to how LCB and state law will define what are “impairing” and “non-impairing” THC compounds and cannabinoids.

Background: Since early 2021, new unregulated cannabinoid products that may be “impairing” (other than delta-9 THC) began being sold online and in stores across the nation. This raised questions nationwide about the legality and possible health impacts of these new products, being sold without age-restriction or regulation. A year ago, the LCB Board issued Policy Statement Number PS-21-01 about THC compounds. In January 2022, the Board adopted a new rule section, WAC 314-55-560 that allows the Board to evaluate additives, solvents, ingredients or compounds used in the production of cannabis products.

During the 2022 legislative session, bills introduced to address concerns about the regulation of these emerging products did not advance to passage. The LCB continues to gather information to inform future policy and rule development within the agency’s current statutory authority.

Public participation on this topic continues with a third session on Cannabis Plant Chemistry.

How were panelists selected?

For the discussion on this topic, LCB invited some of the panelists from previous sessions for their experience in cannabis plant science:

  • Dr. David Gang, Director of the Tissue Imaging and Proteomic Laboratory, WSU
  • Jessica Tonani, CEO of Verda Bio Research
  • Brad Douglass, Organic Chemist, The Werc Shop

Additional panelists may be added. LCB’s Policy and Rules manager Kathy Hoffman will moderate the agency’s third deliberative dialogue on these topics on April 27, 2022.

Meeting outline and agenda

  • The session will begin with information on the topic, introductions, and discussion goals and expectations. The agenda is linked here.
  • Panelists will share their knowledge and experience with the subject matter.
  • Interactive Question and Answer session (using the hand-raising feature in Teams) to allow participants and listeners to ask the panelists questions.
