Colorado pot stores sold a record amount of marijuana in June, a huge leap over the previous record set in March. What's not clear though, is why.
Recreational marijuana sales topped $50 million in June for the first time. Medical marijuana also had its biggest month in more than a year.
Some stores owners speculated that business was driven by the summer weather, lower prices and the expansion of stores into Aurora. Some owners there reported seeing more than 300 customers a day.
At the halfway mark of 2015, Colorado stores have sold nearly half a billion dollars in marijuana and paid about $60 million in taxes to the state.
