A month after Washington became the first state in the nation to legalize marijuana for adult recreational use, the Seattle Police Department has relaxed its rules on previous pot use for job seekers.

Going forward, applicants must not have used marijuana for at least a year before joining the force, police officials said. Previously, the rule was no pot use for three years.

The change was spurred by Washington state's groundbreaking vote last month to legalize the recreational use of marijuana, Assistant Chief Jim Pugel said.
