Missouri has been known for its population's generally "stalwart, conservative, noncredulous" attitude toward regulatory regimes, which is one of the origins of the state's unofficial nickname, the "Show-Me State". As a result, and combined with the fact that Missouri is one of America's leading alcohol states, regulation of alcohol and tobacco in Missouri is among the most laissez-faire in America. For 2013, the annual "Freedom in the 50 States" study prepared by the Mercatus Center at George Mason University ranked Missouri as #3 in America for alcohol freedom and #1 for tobacco freedom (#7 for freedom overall). The study notes that Missouri's "alcohol regime is one of the least restrictive in the United States, with no blue laws and taxes well below average", and that "Missouri ranks best in the nation on tobacco freedom".
