I can see all the states around the pot-legal states passing laws allowing the growth and export of marijuana but not its consumption since that's still against federal law. They may put a 10% tax on each weed transaction in order to get some money themselves and then watch out Colorado! You'll have bandits running weed from the North Dakota border all the way down to Rifle, Colorado.
Can't you see the Colorado law organs pulling over every vehicle at check points on every road and highway leading into Colorado to sniff the cars, one by one. Pretty soon they'll be tunneling into Colorado from New Mexico in order to get passed the border guards and drug detector dogs. They'll be searching every single aircraft and forcing all transiting aircraft to land and be searched so they can assure themselves that they aren't losing good revenue to people who would air drop pot in the great state of legal-weed.
