The only thing I can think of is the states that have legalized Marijuana. It's federally illegal, but the states simply have chosen to not prosecute.
That being said, if you are pulled over by a federal agent in a legal state, if you meet the federal requirements you can still be prosecuted for possession of marijuana at the felony level, that being said, unless you were doing something super sketchy like having a full pound of weed split into little baggies or something, that is unlikely to stick.
