Denver, Colorado (CNN) -- Driving down Broadway, it's easy to forget you are in the United States.

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.
