Missouri marijuana sales have topped half a billion dollars since recreational marijuana was legalized in February of this year. New numbers from the state show Missouri recorded $121.2 million dollars in sales in June, which includes a new record high for recreational marijuana sales. If Missouri keeps going at this rate, over $1 billion in marijuana will be sold this year alone. In May of this year, Missouri hit $1 billion in marijuana sales since when medical marijuana was legalized. About $3 million worth of marijuana has been sold on an average day in Missouri since it was made legal.
