Tonya Snider said she began to use marijuana about four years ago after she was diagnosed with fibromyalgia, a chronic condition characterized by widespread pain in muscles, ligaments and tendons, the Las Vegas Review-Journal said Thursday.

Under state law, police must return seized marijuana and drug paraphernalia if it has been determined they have been used in accordance with the state's Medical Use of Marijuana Act, the newspaper said.

"I think this may be the first time this has happened in Nevada," said Ryan Mortier, Snider's attorney.

The program officer for the state's medical marijuana program said more than 700 people have been issued registration cards to use marijuana.
