The Washington Liquor Control Board has approved draft rules for the state's new marijuana industry.
Four public meetings on the proposed rules will be held across the state Aug. 6-8. The rules are scheduled to take effect Sept. 16.
There were several changes to the preliminary rules that were released in late May. The biggest change is to allow outdoor marijuana grows, rather than limit production to indoors.
Marijuana sales in Washington should begin in early 2014, unless the Justice Department stops them. Pot remains illegal federally.
Last fall, voters made Washington and Colorado the first states to legalize the sale of taxed marijuana to adults over 21 at state-licensed stores.
