In the New York Times, Ethan Nadelmann takes aim at the “reefer madness” of the Obama administration, which despite promises and expectations has stepped up the war on marijuana:

But over the past year, federal authorities appear to have done everything in their power to undermine state and local regulation of medical marijuana and to create uncertainty, fear and confusion among those in the industry. The president needs to reassert himself to ensure that his original policy is implemented.

The Treasury Department has forced banks to close accounts of medical marijuana businesses operating legally under state law. The Internal Revenue Service has required dispensary owners to pay punitive taxes required of no other businesses. The Bureau of Alcohol, Tobacco, Firearms and Explosives recently ruled that state-sanctioned medical marijuana patients can not purchase firearms.

United States attorneys have also sent letters to local officials, coinciding with the adoption or implementation of state medical marijuana regulatory legislation, stressing their authority to prosecute all marijuana offenses. Prosecutors have threatened to seize the property of landlords and put them behind bars for renting to marijuana dispensaries. The United States attorney in San Diego, Laura E. Duffy, has promised to start targeting media outlets that run dispensaries’ ads.

President Obama has not publicly announced a shift in his views on medical marijuana, but his administration seems to be declaring one by fiat.

As bad as the drug war is in the United States, it’s wreaking far more havoc in Mexico and Latin America. That’s why the Cato Institute is holding an all-day conference next week, “Ending the War on Drugs,” featuring:

• the former president of Brazil
• the former drug czar of India
• the former foreign minister of Mexico
• the author of Cato’s study on decriminalization in Portugal
• the Speaker of the House in Uruguay
• plus video presentations by former Secretary of State George Shultz and former Mexican President Vicente Fox.
