Colorado and Washingston states in the United States voted to legalise the use and possession of cannabis in November 2012. On 1 January 2014 Colorado allows stores to sell cannabis, a date dubbed Green Wednesday. Cannabis will be sold like alcohol. Residents will be able to buy up to one ounce, while those from out of the state can purchase up to a quarter of an ounce. Cannabis can only be smoked on private premises, with the permission of the owners.
