Initiative 502 legalizes the production, processing, sale, possession, and use of marijuana and marijuana-infused products within Washington State. It authorizes the Washington State Liquor Control Board (WSLCB) to license and regulate these new systems.
 

I-502 specifically legalizes the following:

Individuals twenty-one years of age or older are legally authorized to possess and use marijuana-related paraphernalia and any combination of:

• One ounce of useable marijuana
• 16 ounces of marijuana-infused product in solid form; or
• 72 ounces of marijuana-infused product in liquid form.

The use or consumption of these products is limited to private homes or establishments. Using marijuana or marijuana-infused products in public is illegal and a ticketable offense. Individuals will be subject to criminal prosecution for:

• Possession in amounts greater than the quantities listed above (over 40 grams is a felony offense)
• Possession of any marijuana or marijuana-infused product by individuals under 21 years of age

Driving under the influence of marijuana is a prosecutable offense. I-502 sets a DUI limit of "delta-9" THC levels greater than or equal to 5 nanograms per milliliter of blood (5 ng/mL). State and local law enforcement agencies are tasked with enforcing this DUI limit.

It is also important to note that individuals or retailers are still subject to prosecution under federal law should the federal government choose to do so.
