Colorado's medical marijuana economics

Driving down Broadway, it's easy to forget you are in the United States. Amid the antique stores, bars and fast-food joints occupying nearly every block are some of Denver's newest businesses: medical marijuana dispensaries.

The locals call this thoroughfare "Broadsterdam." As in Amsterdam, Netherlands, these businesses openly advertise their wares, often with signs depicting large green marijuana leaves.

"The American capitalist system is working," said attorney and medical marijuana advocate Rob Corry.

It's a matter of supply and demand.

"The demand has always been there," he said, "and the demand is growing daily because more doctors are willing to do this, and now businesses, entrepreneurs, mom-and-pop shops are cropping up to create a supply."
