(Olympia, WA) -- One of the newly-passed bills signed into law this week in Washington will allow retail pot-shop customers to get free lock boxes. Under the new law, the lock boxes can be given free to anyone 21 or older, or to a registered medical-marijuana patient who's at least 18 years old. The measure gives licensed marijuana stores an exemption to current state law that bans them from selling anything other than marijuana products and from giving away items. Governor Jay Inslee says the law will help keep young people from accessing marijuana.
