Cannabis Penalties in Washington

Cannabis is legal in Washington, but violating possession limits, growing at home, selling without a license, or consuming in public carries real consequences — from civil fines to felony charges.

Full Penalty Breakdown

Washington's cannabis penalties range from minor civil infractions to serious felonies. The most common violations and their consequences are outlined below.

Offense Classification Penalty
Public consumption Class 3 civil infraction ~$50 fine
Recreational home cultivation Class C felony Up to 5 years / $10,000
Selling without a license Class C felony Up to 5 years / $10,000
Distribution to minors Class B felony Up to 10 years / $10,000
Penalties near schools/parks Double within 1,000 ft
DUI (first offense) Gross misdemeanor 24 hrs jail min, 1-yr interlock
DUI (3rd in 10 years) Felony 90+ days imprisonment

Public Consumption

Consuming cannabis in any public place or in view of the general public is a Class 3 civil infraction under RCW 69.50.445:

Offense Classification Penalty
Public consumption Class 3 civil infraction Approximately $50 fine

While the fine is relatively low, public consumption remains illegal and is enforced by local law enforcement. For a full guide on where consumption is and isn't allowed, see our Where You Can Consume page.

Unlicensed Cultivation (Recreational Users)

Home cultivation for recreational users is one of the most severely penalized cannabis activities in Washington:

Violation Classification Penalty
Growing any number of plants (recreational user) Class C felony Up to 5 years in prison, $10,000 fine

This is a felony charge regardless of the number of plants. A single plant in your closet carries the same classification as a large-scale operation. Only medical patients with a valid authorization or recognition card may grow cannabis at home. See our Home Cultivation Ban page for details.

Unlicensed Sales and Distribution

Violation Classification Penalty
Selling cannabis without a WSLCB license Class C felony Up to 5 years in prison, $10,000 fine
Distributing cannabis to a minor (under 21) Class B felony Up to 10 years in prison, $10,000 fine

Distribution to minors is treated far more seriously than other cannabis offenses. A Class B felony conviction carries up to 10 years in prison and significantly impacts employment, housing, and other aspects of life. This applies whether the distribution is commercial or social — giving cannabis to anyone under 21 is a Class B felony.

Penalty Doubling Near Protected Areas

Penalties for cannabis violations double within 1,000 feet of certain protected areas under Washington law:

  • Schools and school grounds (K-12)
  • Parks and playgrounds
  • Public housing
  • Public transit stops and centers

This enhancement applies to cultivation, distribution, and sale offenses committed within these zones. A Class C felony that normally carries up to 5 years and $10,000 would carry doubled penalties when committed within 1,000 feet of a school, park, public housing, or transit stop.

Enhanced Penalty Zones

In urban areas like Seattle, Tacoma, and Spokane, the 1,000-foot zones around schools, parks, transit stops, and public housing overlap significantly. Many locations in city centers fall within at least one enhanced penalty zone. Violations in these areas face doubled consequences.

DUI Penalties

Cannabis DUI is governed by RCW 46.61.502. Washington's 5 ng/mL per se THC limit means exceeding the threshold is automatic evidence of impairment:

Offense Classification Jail/Prison Ignition Interlock License Suspension
First DUI Gross misdemeanor 24 hours minimum (mandatory) 1 year 90 days–1 year
Second DUI Gross misdemeanor 30 days minimum (mandatory) Extended Extended
Third DUI (within 10 years) Felony 90 days minimum (mandatory) Extended Revocation

A medical cannabis authorization is not a defense against DUI charges. For complete details on the 5 ng/mL standard and vehicle rules, see our DUI & Driving page.

Federal Land: All Cannabis Activity Is Illegal

Cannabis remains illegal under federal law. Within Washington, all cannabis activity — possession, consumption, and transportation — is prohibited on federal property, regardless of state law. Federal land in Washington includes:

  • Mount Rainier National Park
  • Olympic National Park
  • North Cascades National Park
  • National forests (Mt. Baker-Snoqualmie, Olympic, Gifford Pinchot, Okanogan-Wenatchee)
  • Military installations (Joint Base Lewis-McChord, Naval Station Everett)
  • Federal buildings (courthouses, post offices, VA facilities)

Violations on federal land are prosecuted under federal law, which carries its own penalty structure and does not recognize Washington's legalization.
