Measure 91 — The Oregon Cannabis Code

On November 4, 2014, Oregon voters approved Measure 91 with 56% of the vote, making Oregon the fourth state to legalize recreational cannabis (after Colorado, Washington, and Alaska, which voted the same day). The measure was codified as ORS 475C — the Oregon Cannabis Code — with administrative rules under OAR 845.

The timeline moved quickly by legalization standards:

• July 1, 2015: Recreational possession and home growing became legal
• October 1, 2015: Early retail sales began at existing medical dispensaries (limited to flower and immature plants)
• October 1, 2016: Licensed recreational retail stores opened, selling all product types

Oregon chose a production-at-source tax model rather than taxing at every stage. The state levies a 17% excise tax at the point of retail sale, with local jurisdictions allowed to add up to 3% more. Notably, Oregon has no general sales tax, so the cannabis excise tax is the entire tax burden for recreational consumers.

The Control, Regulation, and Taxation of Marijuana and Industrial Hemp Act allows a person twenty-one years of age or older to possess, use, and grow limited amounts of marijuana.

Who Can Buy and What You Need

To purchase recreational cannabis in Oregon, you must:

• Be 21 years of age or older
• Present a valid government-issued photo ID — driver's license, passport, state ID, or military ID from any state or country
• Purchase from an OLCC-licensed retail store

There is no residency requirement. Out-of-state visitors have the same purchase and possession limits as Oregon residents. Oregon does not track or limit the number of dispensary visits per day, though each store must verify your ID for every transaction.

Current Purchase Limits (Updated 2022/2024)

Oregon's purchase limits have been increased twice since legalization, reflecting the state's mature market and oversupply dynamics:

Edible Potency Caps

Recreational edibles are limited to 100mg THC per package and 10mg THC per serving. Medical patients can access higher-potency products, including tinctures up to 4,000mg THC (versus the 1,000mg recreational limit).

Possession Limits

Separate from purchase limits, Oregon law sets how much you can possess at any time:

• In public: Up to 1 ounce of usable flower
• At home: Up to 8 ounces of usable flower

Possession between 2 and 4 ounces in public is a $1,000 violation. Between 4 and 8 ounces is a Class B misdemeanor (up to 6 months and $2,500). For full details, see Possession Limits.

The Opt-Out Landscape

Under ORS 475C, cities and counties may opt out of allowing recreational cannabis businesses (but cannot criminalize possession or home growing). As of 2026:

• 82 cities and 17 counties have opted out of recreational retail
• Major cities that allow cannabis businesses: Portland, Eugene, Bend, Salem, Medford, Ashland, Corvallis
• Opt-out areas tend to be smaller, rural communities
• Some jurisdictions opted out of retail but allow other license types (production, processing)

Even in opt-out areas, personal possession and home cultivation remain fully legal under state law. Only commercial operations are affected.

How Oregon Compares to Neighboring States

Do not cross state lines with cannabis. Even traveling to another legal state is a federal offense. Idaho in particular has zero tolerance enforcement at the Oregon border.

The OLCC: Oregon's Cannabis Regulator

The Oregon Liquor and Cannabis Commission (OLCC) regulates all commercial cannabis activity under ORS 475C. The OLCC handles licensing, compliance inspections, product testing standards, seed-to-sale tracking (via Metrc), and enforcement. A permanent licensing moratorium means no new licenses are being issued — market entry is only possible by purchasing an existing license.
