Someone at the Seattle police department sparked a new idea when the force sought ways to reach out to pot users at the city's 22nd annual Hempfest.

Officers are handing out 1,000 bags of Doritos which direct hungry participants to a page on the department's website entitled "Marijwhatnow? A Guide to Legal Marijuana Use In Seattle."

It explains some of the nuances of Washington's law: that adults can possess up to an ounce but can't sell it or give it away, that driving under the influence of pot is illegal, and that — festivals aside — public use is illegal.

Washington state legalized marijuana last year.

As many as 85,000 are expected to attend the three-day event in Seattle which begins Friday.
