The Florida medical marijuana initiative appears to be in trouble, thanks in part to a deep-pocketed GOP opposition donor, a federal court is hearing evidence on marijuana's scheduling, a new report on Colorado's legalization finds less than meets the eye, Russia bans some new synthetics, and more. Let's get to it:

Florida's medical marijuana initiative faces an uphill battle in the campaign's final days.

Federal Court Hears Arguments on Proper Scheduling of Marijuana. In a federal court hearing in Sacramento that continues today, three medical experts testified that the scientific evidence does not support classifying marijuana as a Schedule I drug under the Controlled Substances Act. This is the first time in living memory that a federal court in a criminal case has allowed discussion of marijuana's proper placement in the drug schedules. Testifying for the defense in US v. Schweder, Gregory Carter, MD, and Carl Hart, PhD, told the court that marijuana is neither "very dangerous" nor "lacking medical use," both of which are required to support a Schedule I placement.

Cincinnati City Council Moves to Fix Its Pot Policy Misstep. Ohio is a state where the possession of marijuana is decriminalized, but in 2006, the Cincinnati city council tried to crack down on it, making possession of even small amounts a misdemeanor offense under city ordinance. The council later repealed that law, admitting it was a mistake. Now, it has moved to undo one of the nastier consequences of its actions, voting Monday to allow people arrested under that ordinance to have their criminal records expunged. More than 10,000 people were arrested under the ordinance, which was in effect until its repeal in 2010.

Cato Report on Colorado Legalization: No Big Deal. For all the sturm und drang surrounding the consequences of marijuana legalization in Colorado, a new report by Harvard economist Jeffrey Miron for the Cato Institute finds it just wasn't that big a deal. Miron found little impact on crime, traffic accidents, or teen drug use -- the banes of the anti-legalization folks -- but neither did he find a big impact on the state's economy. And he found that tax revenues were lower than estimated. Miron's bottom line? "The evidence here indicates that strong claims about Colorado's legalization, whether by advocates or opponents, are so far devoid of empirical support."

Florida's Measure 2 In Danger. A Gravis Marketing poll released Monday has support for the Measure 2 medical marijuana initiative at 50%, with 42% opposed and 8% undecided. Because it is a constitutional amendment, the initiative needs 60% to win. Gravis had the initiative with 62% in August and 55% early this month. On the other hand, the United for Care campaign sent an email to supporters last night claiming its internal polling had the initiative at 61%. Click on the poll link for methodological details.

Republican Money Man Sheldon Adelson Contributes Another $1 Million to Defeat Florida's Measure 2. Las Vegas casino magnate and Republican sugar daddy Sheldon Adelson has thrown another million dollars into the battle to defeat the Measure 2 medical marijuana initiative. Opponents of the initiative have raised $5.8 million to defeat it; Adelson is responsible for $5 million of it. Overall, opponents have spent $5.5 million, pretty much matching supporters, who have so far spent $6.5 million.

Russia Bans Ingredients for New Synthetic Drugs. Russia has expanded its list of banned drugs to include methoxetamine, NM-018, and methylphenidate -- all used to create new synthetic drugs. The move comes after Russian senators proposed earlier this month to ban new synthetics from the moment they are discovered instead of going through the lengthy process of listing them on the Federal Drug Control Services' list of banned drugs.
