Seattle cops sure know potheads: There’s no way a stoner’s gonna turn down a free bag of chips. The Seattle Police Department is taking advantage of Hempfest, the world’s largest pot rally, by distributing information about the limits of legalization laws in the form of stickers attached to Doritos bags. “Distributing salty snacks at a festival celebrating hemp, I think, is deliberately ironic enough that people will accept them in good humor,” said SPD spokesman Sgt. Sean Whitcomb. “We want to make sure people learn the rules and that they respect the vote.” The labels will direct festivalgoers to the Seattle Police Department's marijuana FAQ site, called “Marijwhatnow?” which went viral last November.
