Intelligence agency director Guillermo Valdes also said authorities have confiscated about 84,000 weapons and made total cash seizures of $411 million in U.S. currency and $26 million worth in pesos (330 million pesos).
Valdes released the statistics during a meeting with Calderon and representatives of business and civic groups, where attendees exploring ways to improve Mexico's anti-drug strategy called on the government to open a debate on legalization.
Calderon said he has taken note of the idea of legally regulating drugs in the past.
"It's a fundamental debate in which I think, first of all, you must allow a democratic plurality (of opinions)," he said. "You have to analyze carefully the pros and cons and the key arguments on both sides."
Three former presidents — Cesar Gaviria of Colombia, Ernesto Zedillo of Mexico and Fernando Cardoso of Brazil — urged Latin American countries last year to consider legalizing marijuana to undermine a major source of income for cartels. And Mexico's congress also has debated the issue.
But Calderon has so far said he is opposed to the idea.
"I'm not talking just about marijuana," analyst and writer Hector Aguilar Camin said in proposing the debate Tuesday, "rather all drugs in general."
The most recent official toll of the drug war dead came in mid-June, when the attorney general said 24,800 had died. Valdes did not specify a time frame for the new statistics.
The government does not regularly break down murder statistics, but leading newspapers who kept their own counts say last month was the deadliest yet under Calderon: According to national daily Milenio, 1,234 were killed in July.
The Mexican government says most victims were involved in the drug trade.
Some attendees criticized the government for lacking consistent statistics on the drug war and an effective way to communicate its successes. They also said the government needs to do more to combat the financial arm of organized crime.
"There's no systematic policy for investigating or seizing the assets of organized crime," said Jose Luis Pineyro of Mexico's Autonomous Metropolitan University, "nor a system of locating the properties of organized crime."
