Is Weed Legal in Washington? Everything you need to know

Reading Time: 8 minutes

Washington State has been a pioneer in cannabis legalization, setting a precedent for both medical and recreational use in the United States. Since legalizing medical marijuana in 1998 and recreational use in 2012, the Evergreen State has developed a robust framework for cannabis regulation, making it one of the most progressive states for cannabis policy. Whether you’re a resident, a visitor, or a patient seeking relief, understanding Washington’s cannabis laws is essential to stay compliant and make informed choices. This guide covers the legal status of cannabis, possession limits, medical marijuana programs, workplace considerations, and what the future might hold, all grounded in the latest regulations and data.

Recreational Marijuana: Legal and Regulated

Washington made history in 2012 by becoming one of the first states, alongside Colorado, to legalize recreational marijuana through Initiative 502 (I-502). Approved by 55.7% of voters, I-502 legalized the possession, use, and sale of marijuana for adults aged 21 and older. The first legal recreational sales began on July 8, 2014, marking a significant shift from prohibition to a regulated market overseen by the Washington State Liquor and Cannabis Board (LCB).

Adults 21 and older can legally purchase and possess the following amounts of cannabis for recreational use:

• 1 ounce (28 grams) of usable marijuana (flower or bud).
• 16 ounces (453 grams) of marijuana-infused solid products, like edibles.
• 72 ounces (2,041 grams) of marijuana-infused liquid products, like beverages.
• 7 grams of marijuana concentrates, like oils or waxes.

Purchases must be made at state-licensed retail stores, which are subject to a 37% excise tax on top of standard state and local sales taxes. These stores require a valid photo ID to verify age, and no one under 21 is allowed on the premises. Unlike some states, Washington does not require residency, so visitors can also buy cannabis, but all products must be consumed within state borders. Transporting cannabis across state lines, even to other legal states, is illegal under federal law.

Public consumption of cannabis is prohibited. You cannot smoke, vape, or consume edibles in public places like parks, sidewalks, restaurants, or concerts. Violations can result in a civil infraction with a $100 fine. Cannabis use is also banned in areas where tobacco smoking is prohibited, such as bars, workplaces, and indoor public spaces, per Washington’s Smoking in Public Places law (RCW 70.160).

Medical Marijuana: A Long-Standing Program

Washington legalized medical marijuana in 1998 through Initiative 692, the Medical Use of Marijuana Act, passed with nearly 60% of the vote. This law allows patients with qualifying conditions to use cannabis with legal protections, including possession of larger amounts than recreational users and the ability to grow plants at home. The program is overseen by the Washington State Department of Health, and registration in the state’s medical marijuana database is voluntary but offers additional benefits.

Qualifying conditions for medical marijuana include:

• Cancer, HIV, or other diseases causing severe nausea, cachexia, or weight loss.
• Epilepsy or other seizure disorders.
• Multiple sclerosis or other conditions causing spasticity disorders.
• Intractable pain unrelieved by standard treatments.
• Glaucoma, Crohn’s disease, or hepatitis C with debilitating symptoms.
• Post-traumatic stress disorder (PTSD).
• Traumatic brain injury or other conditions approved by the state.

Registered patients can possess:

• 3 ounces (85 grams) of usable marijuana.
• 48 ounces (1,360 grams) of marijuana-infused solid products.
• 216 ounces (6,124 grams) of marijuana-infused liquid products.
• 21 grams of marijuana concentrates.

Unregistered patients with a valid medical authorization can possess smaller amounts: up to 1 ounce of usable marijuana, 16 ounces of solid edibles, 72 ounces of liquid products, and 7 grams of concentrates. Registered patients can also grow up to 6 plants (with a maximum of 3 flowering) and possess up to 8 ounces of usable marijuana from their plants. With a healthcare provider’s recommendation, registered patients may grow up to 15 plants and possess 16 ounces of usable marijuana.

Medical marijuana patients benefit from tax exemptions. Unlike recreational sales, medical purchases at medically endorsed stores are exempt from the 37% excise tax and retail sales tax, making cannabis more affordable for patients. These stores also offer specialized products and consultations tailored to medical needs.

How to Get a Medical Marijuana Card in Washington

Obtaining a medical marijuana card in Washington is straightforward but requires a healthcare provider’s authorization. Here’s a step-by-step guide:

1. Consult a Healthcare Provider: Visit a licensed healthcare professional (physician, naturopath, physician assistant, or advanced registered nurse practitioner) who can diagnose a qualifying condition and recommend medical cannabis. The provider must complete a medical marijuana authorization form.
2. Obtain Authorization: The authorization form, signed by your provider, confirms your eligibility. It includes details about your condition and recommended cannabis use.
3. Register (Optional): Take the authorization to a medically endorsed retail store to join the state’s medical marijuana database. Registration costs $1 and provides a recognition card, which grants higher possession limits, home cultivation rights, and tax exemptions. Minors under 18 need a designated caregiver to register on their behalf.
4. Purchase at Medically Endorsed Stores: Use your authorization or recognition card to buy medical cannabis products at licensed retailers with medical endorsements. These stores are listed on the LCB’s website.

For a seamless process, services like Kif Doctors offer online consultations to connect patients with authorized providers. I always recommend going for a Medical Marijuana Card Online Instantly to simplify the application and ensure quick access to medical benefits.

Caregivers can also register to assist minors or patients unable to manage their own care. Caregivers must be 21 or older, pass a background check, and be designated by the patient or their legal guardian.

Where to Buy Cannabis in Washington

Washington has a well-established network of licensed cannabis retailers, with over 400 recreational and medically endorsed stores statewide. Popular chains like Cinder in Spokane and HWY 420 offer a wide range of products, from flower and edibles to concentrates and topicals. Retailers are regulated by the LCB, ensuring products are tested for safety and labeled for THC content.

Visitors and residents can find dispensaries in major cities like Seattle, Spokane, and Tacoma, as well as smaller towns. Websites like Leafly and Weedmaps provide directories to locate nearby stores. Most dispensaries accept cash only due to federal banking restrictions, though some offer ATMs or debit card options. Always bring a valid ID, as age verification is mandatory.

Home Cultivation: Medical Patients Only

One of Washington’s stricter rules is its prohibition on home cultivation for recreational users. Growing cannabis without a medical authorization or state license is a Class C felony, punishable by up to 5 years in prison and a $10,000 fine. This makes Washington one of the few legalization states, alongside Illinois and New Jersey, where recreational home growing is banned.

Medical marijuana patients, however, can grow cannabis at home under specific conditions. Registered patients can cultivate up to 6 plants (3 flowering) and possess 8 ounces of usable marijuana. With a provider’s recommendation, they can grow up to 15 plants and possess 16 ounces. Unregistered patients with a valid authorization can grow up to 4 plants and possess 6 ounces. Plants must be grown in a private residence, out of public view, and secured to prevent unauthorized access.

Efforts to legalize recreational home cultivation, such as House Bill 1019, have repeatedly failed in the legislature, despite support from advocates who argue it would align Washington with other legal states. Opponents cite concerns about unregulated production and potential diversion to the black market.

Driving and Cannabis: Strict DUI Laws

Driving under the influence of cannabis is illegal in Washington, with a zero-tolerance policy for THC in the bloodstream. The legal limit is 5 nanograms of active THC per milliliter of blood. Penalties for a first-time DUI offense include up to 90 days in jail, a $1,000 fine, and a 90-day license suspension. Repeat offenses carry harsher consequences, including longer jail time and higher fines.

Cannabis in vehicles must be stored in a sealed container or the trunk, inaccessible to the driver and passengers. Open containers or partially consumed products in the passenger compartment are illegal, even if the driver is sober. Passengers are also prohibited from consuming cannabis in a vehicle.

These laws reflect Washington’s commitment to public safety, as THC can impair coordination and reaction time. If you plan to consume cannabis, arrange alternative transportation to avoid legal trouble.

Workplace and Housing: Employer and Landlord Rights

Washington’s cannabis laws do not protect employees from workplace drug policies. Employers can maintain drug-free workplaces and test for cannabis, even for legal off-duty use. A positive THC test can lead to termination, denial of hiring, or loss of unemployment benefits, particularly in safety-sensitive industries like transportation or healthcare.

In 2023, the state passed Senate Bill 5123, which prohibits employers from discriminating against job applicants based on cannabis use, effective January 1, 2024. However, this protection applies only to pre-employment testing and has exceptions for roles requiring federal background checks, law enforcement, firefighting, corrections, and aerospace positions. Post-accident or reasonable suspicion testing remains permissible, and employers can still enforce zero-tolerance policies for on-the-job use [Washington State Legislature].

Landlords also have the right to prohibit cannabis use or cultivation on their properties, even for medical patients. Many rental agreements include clauses banning smoking or growing cannabis, citing federal law or property damage concerns. Tenants should check lease terms and discuss medical needs with landlords to avoid eviction or penalties.

Hemp and CBD: Federally Compliant and Accessible

Hemp-derived products, including CBD with 0.3% or less THC, are legal in Washington under the 2018 federal Farm Bill. These products are widely available at retail stores, online, and even grocery stores, with no medical card required. Washington regulates hemp production and sales through the Department of Agriculture, ensuring compliance with THC limits and safety standards.

Medical patients may use CBD products with higher THC content if purchased through medically endorsed stores. Consumers should verify product labels and third-party lab reports to ensure compliance, as mislabeled products could inadvertently violate state law.

The Future of Cannabis in Washington

Washington’s cannabis industry is thriving, generating over $1.5 billion in annual sales and contributing significant tax revenue to state and local governments. The state has implemented social equity programs, such as the 2020 Social Equity in Cannabis Task Force, to address disparities in licensing and support minority-owned businesses. In 2022, the Task Force recommended issuing additional licenses to promote equity, a process ongoing as of 2025.

Legislative efforts continue to refine cannabis policy. Senate Bill 5069, signed in 2023, allows interstate cannabis commerce with other legal states, pending federal legalization. This could position Washington as a leader in regional cannabis trade. Meanwhile, advocates push for recreational home cultivation and broader expungement of past marijuana convictions, though these face resistance from lawmakers concerned about enforcement and public safety.

Public sentiment strongly supports legalization, with polls showing over 60% of Washingtonians favoring the current system. Events like Seattle Hempfest, which draws over 100,000 attendees annually, underscore the state’s vibrant cannabis culture. However, federal prohibition remains a challenge, limiting banking access for businesses and creating legal risks for interstate transport.

Washington’s progressive stance is tempered by strict regulations, reflecting a balance between access and control. As federal policy evolves, the state is well-positioned to adapt, potentially expanding its market and influence in the national cannabis landscape [Washington State Liquor and Cannabis Board].
