More than 100,000 people visited a first-of-its-kind pop-up shopping area and on-site consumption lounge at the recent California State Fair, breaking new mainstream ground for the cannabis industry and setting a trend that could spread across the country.

The family-friendly festival, in its 170th year—featuring carnival rides, rock concerts, fried snacks and sweltering weather—was the first in America to allow cannafans to buy and consume weed on the premises.

The tightly regulated program drew scouting missions from Nevada and several other states, with government officials taking note of the layout, guidelines and partnerships that gelled to create the 21-and-older “California Cannabis Experience.”
