What are the medical marijuana laws in Washington?

Medical cannabis laws in Washington

1979

The state of Washington recognizes a legal defense for medical cannabis use in the case of State v. Diana.

1990s

Cannabis clubs were established to provide cannabis to medical patients.

1997

Initiative 685 to legalize medical marijuana is proposed but fails.

1998

Initiative 692 decriminalizes cannabis and effectively establishes a medical marijuana program, as it allows physicians to recommend medical marijuana to patients with terminal or debilitating illnesses, including: “chemotherapy-related nausea and vomiting in cancer patients; AIDS wasting syndrome; severe muscle spasms associated with multiple sclerosis and other spasticity disorders; epilepsy; acute or chronic glaucoma; and some forms of intractable pain.”

2015

Washington establishes the Cannabis Patient Protection Act.

Recreational cannabis laws in Washington

2003

Seattle passes an initiative to make adult marijuana possession the lowest priority of law enforcement agencies in the city.

2010

Two bills were proposed, one which would have legalized liquor store sales and the other decriminalized possession of 40 grams or less of cannabis, and both bills died. Initiative 1068 is also proposed, which would have removed all state-level penalties for cannabis use or possession for adults aged 18 or over.

2011

Initiative 502 was introduced and received enough signatures to be sent to the state legislature. In April 2012, when the legislature adjourned without acting, the initiative advanced to the 2012 general ballot.

2012

Initiative 502 is passed. Adults’ possession of up to 1 ounce (28 g) of marijuana became legal under state law on December 6. However, cultivation, sale, and even gifting remained illegal.

How do I get certified for medical cannabis in Washington?

Leafwell is not yet open in Washington, but you can become a medical card holder. You must be 18 years old or over to undergo a medical cannabis evaluation and get certified. Those under this age must apply as minors and have a caregiver 21 or over responsibility for the patient’s care.

Get approved by a doctor, then apply to the state medical marijuana program. Receive your MMJ card and start shopping for your medical cannabis from a licensed dispensary. You can see the Washington State Department of Health Medical Marijuana Program overview here.


Is telemedicine allowed for medical cannabis consultations in Washington?

Yes, telemedicine is legal in Washington, and you can get certified for cannabis online.


How much cannabis can I possess in Washington with an MMJ Card?

Adults age 21 and over can purchase:

  • up to 1 ounce of useable marijuana (the harvested flowers, or “bud”);
  • 16 ounces of marijuana-infused edibles in solid form;
  • 72 ounces in liquid form; or
  • 7 grams of marijuana concentrates.

Those entered in the state’s voluntary patient database may possess:

  • 3 ounces of useable marijuana (the harvested flowers, or “bud”);
  • 48 ounces of marijuana-infused product in solid form;
  • 216 ounces of marijuana-infused product in liquid form; or
  • 21 grams of marijuana concentrates.

Recognized card holders may also grow in their homes or as a member of a cooperative:

  • Six plants for personal medical use;
  • Possess up to eight ounces of usable cannabis produced from their plants

If the patient’s health care practitioner determines the patient requires more than the presumptive amount, they may authorize:

  • Up to 15 plants for personal medical use;
  • May possess 16 ounces of usable cannabis produced from their plants.

A qualifying patient with authorization may grow up to four plants. Those enrolled in the state medical marijuana program may legally grow between six and 15 plants and possess up to eight ounces if registered in the database and six ounces if not. Those medical patients who wish to grow above six plants need a physician’s recommendation.


Does Washington accept out-of-state cards?

Washington does not have medical marijuana reciprocity and does not recognize other states’ medical marijuana cards.


Will my Washington card be accepted in other states?

A Washington medical marijuana card may be used in some states with medical marijuana reciprocity.

The following states accept or recognize out-of-state medical marijuana cards:

  • Arizona
  • Maine
  • Massachusetts
  • Michigan
  • Montana
  • Nevada
  • New Hampshire
  • New Jersey
  • New Mexico
  • Oklahoma
  • Puerto Rico
  • Rhode Island
  • U.S. Virgin Islands
  • Utah
  • Washington, D.C.

However, this does not always mean you can purchase cannabis at a medical marijuana dispensary (non-medical adult use is acceptable) – just that the state’s medical marijuana laws protect you to some extent. It is wise to call the dispensary ahead if you are a medical cannabis patient from another state and intend to purchase medical marijuana.

The qualifying condition usually has to match between states, so if your qualifying condition is accepted in one state and not your visiting state, your recommendation is not necessarily valid. You are also accountable to the visiting state’s medical marijuana laws, not the state that issued your card.

The following states accept out-of-state applications, allowing visiting patients to use medical cannabis for the duration of their stay:

  • Arkansas
  • California
  • Hawaii
  • West Virginia (cancer patients only)

Are there employment laws protecting medical cannabis cardholders in Washington?

Employers may still conduct drug testing per their legally adopted policies. Medical marijuana patients do not have specific protections in place.


What are the medical cannabis product testing requirements in Washington?

Currently, the state requires adult-use cannabis to be tested for:

  • Potency, including THC and CBD levels
  • Microbial contamination, such as from mold, fungus, or bacteria
  • Mycotoxins, or toxic chemicals produced by microorganisms
  • Moisture, which can increase the risk of microorganism contamination

Where is it safe to purchase cannabis in Washington?

In all states with a medical marijuana program, the only way to purchase medicinal cannabis products is via a legally-licensed dispensary or pharmacy or another legally designated space to buy cannabis. Only those with a legal license to sell cannabis can do so.


Where is it safe to consume marijuana in Washington?

All states with a medical marijuana program have some restrictions on where a person can legally use cannabis. Near schools, nurseries, parks, or other places where children are expected to be, using cannabis is illegal. Use of cannabis on or in federal land or buildings, hospitals, or other such healthcare space is also illegal. Private members’ clubs and landowners may also prohibit cannabis use on their property or restrict it at their discretion.

The safest place to use medical cannabis is in the safety of your own home. It is wise to use common sense, generally keep consumption out of public view, and utilize discreet consumption methods wherever possible.
