FILE - In this March 2011, file photo, employees of Montana Cannabis, are detained as federal agents and local authorities raid the medical marijuana operation in Helena, Mont. A medical marijuana law approved by the state's voters in 2004 left gray areas when it came to regulation, police authority and commercial sales. When the number of registered pot providers topped 4,800 with billboard ads and huge greenhouses operating in the open, the feds stepped in. (AP Photo/The Independent Record, Eliza Wiley)
