Washington Initiative 502 legalizes marijuana in Washington State. The measure shall, “license and regulate marijuana production, distribution, and possession for persons 21 years of age or older; remove state-law criminal and civil penalties for the activities that it authorizes; tax marijuana sales; and earmark marijuana related revenues.” Retail stores will be established only after the issuance of a license. These businesses must be 1,000 feet away from public schools. While private use is decriminalized, public use remains a civil infraction. Driving under the influence of marijuana will result in DUI prosecution. Personal grows, except for medical cannabis, will remain illegal. Selling or distributing unlicensed marijuana remains illegal. Legal users may possess up to one ounce of usable marijuana, 16 ounces of marijuana-infused product in a solid form, and 72 ounces of marijuana in a liquid form.
