Accidentally brought your marijuana to the Aspen/Pitkin County Airport ? Do n't worry . Pitkin County Sheriff Joe DiSalvo plans to install amnesty boxes at the airport , possibly as soon as next week , for people traveling out of state . `` We 'll have signs around the airport saying that although marijuana is legal in this state , it may be illegal in your final destination , '' DiSalvo told CNN . `` This is an opportunity to dispose of your marijuana with no legal consequences . '' But do n't try to fly with that marijuana , not even departing from the pot-happy states of Colorado and Washington . Both states allow adults 21 and older to have up to an ounce of marijuana , but those policies are at odds with federal law . Leave the brownies at home , too -- even in states where it 's legal , it 's not yet clear how marijuana-laced food is evaluated under those limits . The Transportation Security Administration seized 36 ounces of marijuana-laced food in a passenger 's checked luggage at the Aspen airport earlier this month , and the federal agency referred the case to the Pitkin County Sheriff 's Office , DiSalvo confirmed . ( The edibles ' amount of THC , the active ingredient in cannabis , was much less than the weight of the food . The sheriff 's office declined to press charges . ) The story was first reported in the Aspen Daily News . Colorado 's recreational marijuana stores make history . In fact , the TSA has called the sheriff several times over the past six months to report passengers carrying marijuana and related products , DiSalvo said . His office offers to dispose of the product before passengers depart the state . `` Most everybody heeds our warnings , '' he said . The larger conflict is between state and federal law . While Colorado and Washington allow some marijuana use , federal law has n't changed . And it 's probably not a good idea to test the TSA or other federal agencies at the nation 's airports . If they find a substance that violates federal law , they can refer possible violations to federal , state or local law enforcement in any state . Still , pot is n't exactly the TSA 's top priority . Denver International Airport bans pot despite Colorado 's new marijuana law . `` TSA 's focus is on terrorism and security threats to the aircraft and its passengers , '' TSA spokesman Ross Feinstein wrote in a statement . `` TSA 's screening procedures , which are governed by federal law , are focused on security and are designed to detect potential threats to aviation and passengers . As has always been the case , if during the security screening procedures an officer discovers an item that may violate the law , TSA refers the matter to law enforcement . Law enforcement officials will determine whether to initiate a criminal investigation . '' It can be hard to sort out the competing state and federal regulations , especially for the dazed and confused passenger . The Colorado Springs airport has already placed amnesty boxes for people to get rid of their marijuana before clearing security or getting on an airplane . The Denver International Airport decided not to play with pot , banning the substance entirely at the airport , a spokeswoman confirmed . Seattle-Tacoma International Airport does n't ban legal amounts of marijuana at the airport . That 's because Washington state law does n't allow facilities to add any additional regulation , airport spokesperson Perry Cooper said . A word of caution to Super Bowl fans from Colorado and Washington : Do n't try to take your marijuana to less pot-friendly states . We know your ( possible ) cannabis consumption wo n't get in the way of the game , but consider where the Super Bowl is being played . If your pot makes it to your destination , you could be dealing with the Port Authority of New York and police guarding Kennedy and LaGuardia airports in New York and Newark airport in New Jersey . How do you think will they react if your goods are discovered ? `` If they 're possessing contraband in New York or New Jersey , '' Port Authority spokesman Joe Pentangelo said , `` the prevailing laws would apply . '' Recreational pot sales : Where the grass is much greener .
Colorado and Washington state airports are seeing passengers try to depart with pot . The TSA has seized marijuana-laced products from checked baggage . Score: 6 The Seattle airport can not ban pot on its premises , according to state law .
