WA SB6328

Replaces the current 37% ad valorem cannabis excise tax with a weight-based and potency-based tax structure: usable cannabis/prerolls taxed at $1.50-$2.50 per gram (tiered by weight), cannabis trim at $0.50-$1.00 per gram, concentrates at $0.01187 per mg THC, solid edibles/topicals at $0.07427 per mg THC, and liquid edibles at $0.04051 per mg THC.

Maintains the existing medical cannabis tax exemption for qualifying patients and designated providers with recognition cards through June 30, 2029.

Adds new statutory definitions for cannabis product categories including "cannabis flower," "cannabis trim," "cannabis edibles in liquid form," "cannabis edibles in solid form," "cannabis topical," and "preroll."

Removes the requirement for the Liquor and Cannabis Board to submit biennial reports to the legislature comparing sales data, tax collections, and market conditions before and after tax changes.

Section 1 (containing the new tax structure with one version of definitions) expires June 30, 2027, at which point Section 2 (containing an alternate version of definitions aligned with other pending legislation) takes effect.
