WA SB6129

Consolidates and restructures Washington's taxation of tobacco, nicotine, and vapor products by repealing Chapter 82.25 RCW (vapor products tax) and merging it into Chapter 82.26 RCW under a unified "nicotine products" framework, effective July 1, 2027.

Imposes a 90% tax on all nicotine products based on taxable sales price, plus an additional 10% tax on flavored nicotine products, which are defined as products with tastes, smells, or sensations other than tobacco.

Adds a new cigarette tax of $0.09875 per cigarette (approximately $1.975 per pack), adjusted for inflation every four years beginning January 1, 2032, plus an additional $0.025 per cigarette tax on flavored cigarettes, effective January 1, 2028.

Directs vapor product tax revenue to the Andy Hill Cancer Research Endowment Fund (up to $10 million/year) and the Foundational Public Health Services Account (up to $20 million/year), with both caps adjusted annually for inflation beginning January 2029.

Authorizes the governor to renegotiate tribal tax compacts to reflect the new tax rates and requires tribal taxes on flavored products to match state rates.
