By the end of 2013, any visitor to the town of Breckenridge in Colorado, USA, will be able to buy cannabis from licensed stores, provided they are over 21.

The town decriminalised cannabis in 2010 but currently anyone wanting to buy it must have a recommendation from a doctor.

As Heather Alexander explains, Breckenridge is standing by to see how the new freedom will affect tourism. Will visitors flock to its stores or will people be deterred from coming at all?
