(1) Nothing in this chapter permits anyone other than a validly licensed cannabis processor to use butane or other explosive gases to extract or separate resin from cannabis or to produce or process any form of cannabis concentrates or cannabis-infused products that include cannabis concentrates not purchased from a validly licensed cannabis retailer as an ingredient. The extraction or separation of resin from cannabis, the processing of cannabis concentrates, and the processing of cannabis-infused products that include cannabis concentrates not purchased from a validly licensed cannabis retailer as an ingredient by any person other than a validly licensed cannabis processor each constitute manufacture of cannabis in violation of RCW 69.50.401. Cooking oil, butter, and other nonexplosive home cooking substances may be used to make cannabis extracts for noncommercial personal use.
(2) Except for the use of butane, the board may not enforce this section until it has adopted the rules required by RCW 69.51A.270.
