SEATTLE -

Washington state is changing its plans for where marijuana businesses can be located, after the Justice Department reiterated that enforcing federal drug laws near schools and playgrounds remains a priority.

Federal law doubles the criminal penalty for producing or distributing controlled substances within 1,000 feet of a school, playground or public housing.

The state Liquor Control Board announced last week that to ease some zoning restrictions for licensed marijuana businesses, it would measure that distance by the path of most common travel, rather than as the crow flies.

But the DOJ plans to continue enforcing the law as it has been, and any pot business within 1,000 feet of a school or playground -- as measured by a straight line -- is at risk of prosecution.

Marijuana industry lobbyist Ezra Eickmeyer says a board member told him Friday it will change the rule in accord with federal law.

The board declined to comment but scheduled an announcement for 2 p.m.
