But some legal scholars and policy analysts say the government will not be able to require California to help in enforcing the federal marijuana ban if the state legalizes the drug.

Without assistance from the state's legions of narcotics officers, they say, federal agents could do little to curb marijuana in California.

"Even though that federal ban is still in place and the federal government can enforce it, it doesn't mean the states have to follow suit," said Robert Mikos, a Vanderbilt University law professor who recently published a paper about the issue.

Nothing can stop federal anti-drug agents from making marijuana arrests, even if Californians legalize pot, he said. However, the U.S. government cannot pass a law requiring local and state police, sheriff's departments or state narcotics enforcers to help.

That is significant, because nearly all arrests for marijuana crimes are made at the state level.
