Oregon's cannabis tax structure is one of the simplest in the country: a flat 17% state excise tax at the retail level, with no wholesale or cultivation tax and no general sales tax. Since recreational sales began in 2015, the state has collected more than $1 billion in cannabis tax revenue, funding schools, mental health services, law enforcement, and drug treatment programs.

Tax Structure

Oregon's cannabis tax has three key characteristics that distinguish it from most other states:

Why Oregon's Approach Is Unusual

• No general sales tax. Oregon is one of five states with no general sales tax. The 17% cannabis excise tax is the only state-level tax on cannabis purchases.
• Retail-only taxation. Unlike states that tax at cultivation, wholesale, and retail levels, Oregon collects tax only at the point of sale to the consumer. This simplifies compliance and avoids tax pyramiding.
• Generous medical exemption. OMMP patients pay zero tax on cannabis — no state excise, no local tax. This is one of the strongest medical exemptions in the country.

Revenue by Year

Oregon's cannabis tax revenue grew rapidly through 2021 before declining alongside the oversupply-driven price collapse:

Revenue peaked at $177.8 million in 2021 during the pandemic consumption boom, then declined 38% as wholesale prices collapsed and the market contracted. The Oregon Health Authority projects a $26.2 million shortfall relative to budget forecasts — a significant gap that affects all downstream revenue recipients.

Local Tax Revenue

In addition to the state excise tax, 109 local jurisdictions levy the optional 3% local tax. Through 2024, local taxes have generated an additional $166 million in revenue for cities and counties that host cannabis businesses. This local revenue is a powerful incentive for municipalities to allow cannabis operations within their borders.

Where the Money Goes

The Measure 91 formula distributes cannabis tax revenue according to a specific allocation, capped at $11.25 million per quarter ($45 million per year):

Above the Cap: Measure 110 Funding

Revenue exceeding the $45 million annual cap flows to the Drug Treatment and Recovery Services Fund, established by Measure 110 in 2020. This fund received approximately $210 million in the 2021–23 biennium, making cannabis tax revenue the primary funding source for Oregon's expanded drug treatment infrastructure.

With revenue declining from the 2021 peak, the Drug Treatment Fund faces significant pressure. The $26.2 million OHA shortfall directly reduces available treatment funding — a painful irony given that the fund was created precisely when cannabis revenue was at its highest and most likely to decline.

Cumulative Impact

Since the first cannabis tax dollar was collected in 2015, Oregon has generated:

• $1+ billion in state excise tax revenue
• $166 million in local tax revenue through 2024
• $7.569 billion in cumulative cannabis sales
• Hundreds of millions directed to schools, treatment, and law enforcement

How Oregon Compares

Oregon's 17–20% effective tax rate is moderate compared to other legal states:

• Oregon: 17–20% (excise + local)
• Washington: 37% excise
• California: ~30%+ (excise + cultivation + sales)
• Colorado: ~29% (excise + sales)
• Alaska: Weight-based ($50/oz cultivator)
• New Jersey: ~8.6–9% (sales + SEEF + local)

Oregon's comparatively low rate was designed to undercut the illicit market — a strategy that succeeded initially but has been overwhelmed by the oversupply crisis driving prices to unsustainable lows.

Oregon cannabis tax revenue peaked at $177.8 million in 2021 and has since declined 38%. Cumulative state tax revenue exceeds $1 billion. Local jurisdictions have collected an additional $166 million through 2024.
