A House committee held a public hearing on a bill that would tax marijuana brand names and trademarks that could be registered in the state when sale of state-taxed recreational marijuana starts at the end of this year.

The bill, which had a public hearing before the House Finance Committee Friday, would tax "all trademarks, trade names, brand names, patents and copyrights that are related to marijuana." The tax would be set at $3.60 per $1,000 of assessed value.

Democratic Rep. Jeff Morris of Mount Vernon says that the money would go toward agricultural research tied to health benefits. During Friday's hearing he specifically cited research being done at Washington State University on creating plasma from wheat, and making gluten-free wheat.
