While possession of marijuana under Washington State law was legalized, there are still numerous restrictions.

Restrictions to the Legal Use of Marijuana

It is important to note the following:

  • Marijuana can only be bought and sold through licensed retailers, and a person must show a valid state-issued ID in order to be on the seller’s premises.

  • You must be at least 21-years-old to purchase or possess marijuana.

  • When purchasing marijuana, you are limited to one ounce of usable harvested flowers, 16 ounces of infused edibles in solid form, and 72 ounces in liquid form.

  • It is against the law to drive under the influence of marijuana. You can expect to be charged with a DUI if you have more than five nanograms of active THC per mL of your blood.

  • Marijuana cannot be consumed in public.

  • State and federal laws prohibit you from taking legally-purchased marijuana out of Washington.
