On January 1, the first day marijuana became legal for recreational use in Colorado, the state’s 24 shops selling the drug reported an estimated over $1 million in sales, Colorado’s KUSA-TV reports. The state estimates that, by year end, pot retailers will make $600 million in sales and the state will generate $67 million in tax revenue.

Shoppers flooded the new stores, many standing in long lines and enduring stormy weather to buy America’s first legal recreational marijuana. Aside from a few citations for public smoking, Colorado’s top marijuana regulator of the Department of Revenue, Barbara Brohl, said, “Everything’s gone pretty smoothly.”

Coloradans must be 21 years or older to buy marijuana; residents can buy up to an ounce at a time while out-of-state consumers are limited to a quarter of an ounce. Smoking pot in public places remains illegal.
