Opponents of a measure to legalize medical marijuana in Arizona saw their advantage grow slightly Monday as election officials continue to count ballots.
Proposition 203 is failing by more than 6,500 votes out of more than 1.5 million counted. Opponents' advantage grew by more than 1,000 votes from Saturday night to Monday.
However, thousands of early ballots and provisional ballots remain to be counted across the state and the initiative remains too close to be called by The Associated Press.
Medical marijuana proposals in 1996 and 1998 were approved but they never took effect. A more sweeping 2002 proposal lost.
This proposal would allow the use of the drug only for serious diseases including cancer.
