Legislators from Mexican President Felipe's Calderon's National Action Party (PAN -- Partido de Accion Nacional) have introduced a bill in the Mexican Senate that would decriminalize the possession of small amounts of drugs for "addicts." An even stronger drug reform bill that included higher personal drug possession limits and would have applied to all drug consumers passed both the Mexican Senate and Congress, only to be vetoed by then President Vicente Fox after strong objections from Washington.

Under this year's version of the bill, which was introduced in the Senate Wednesday, people caught for the first time with less than two grams of marijuana and similarly small single-dose amounts of other drugs, such as cocaine and methamphetamine, would not be prosecuted. But persons caught more than once in possession of illegal drugs would be prosecuted unless they qualified as "addicts" by proving they were in drug treatment or under medical care. The bill retains a provision that would protect indigenous people engaging in religious drug use from prosecution.

But the proposed legislation may not mark a liberalization of Mexico's drug policy, but may instead broaden Mexico's ability to arrest and prosecute drug offenders by allowing state police and judicial systems to take action against drug offenders under them. Under current law, that ability is reserved to the federal government. The bill would allow authorities to concentrate on drug traffickers by freeing up resources to go after dealers, and it increases prison sentences for drug trafficking offenses.

"This isn't legalization," said PAN Sen. Alejandro Gonzalez, who heads the Senate's justice commission. "We're going to go much harder against drug dealers," he told a Mexico City press conference Monday.

Since taking office in December, President Calderon has declared war on Mexico's violent drug trafficking organizations with a vengeance. He has sent thousands of troops into hotbeds of drug trafficking, such as the state of Michoacan, as well as major cities plagued by prohibition-related violence and corruption, such as Tijuana and Acapulco.

Last year's version of the bill set higher personal use quantities, causing it to ultimately be vetoed, said Gonzalez. "An error was made, unfortunately, in the lower house, adding the (exemption for) consumers. That really betrayed the spirit of the reforms, by increasing (personal use) quantities, and that's why we're paying attention to the criticisms and making changes," he noted.

Is "the spirit of the reforms" then to facilitate Mexico's drug war rather than end it?
