DENVER — Among the many oddities that have arisen from marijuana legalization in Washington and Colorado is this: It can be easier to get through airport security with a bag of weed than a bottle of water.

At Washington's airports, including Seattle-Tacoma International, there's nothing police can do to prevent travelers from flying with pot in their carry-on or checked luggage, provided it doesn't exceed the state legal limit of one ounce. Instead, airport officials say, officers simply recommend that travelers leave it in their cars, toss it or have a friend pick it up.
But in Colorado, where the legal pot law gives property owners more authority to restrict the drug, some airports have banned marijuana possession and enacted penalties, including fines as high as $2,500 and a jail stint at the airport in Colorado Springs.
