Mexico's Catholic bishops have issued a stinging criticism of the government's anti-drug efforts, saying it was unable to halt a spiral of violence because corruption has eaten too far into the system.

The nation's bishops made the claims in a document released Thursday in response to a Vatican conference on the drug problem last year. They also made proposals to counter illegal drugs trafficking and addiction in Mexico up to 2000."Violence and the struggle between cartels has converted Mexico into a stage for death and violence that government forces cannot contain, be it because the situation has spun beyond their control, or because of the complicity that has corrupted many structures of control or persecution of narco-traffickers," the document by the Mexican Episcopal Conference said.

It did not elaborate on the claims.

The bishops urged an end to the lack of communication between the government and the Catholic Church in fighting drug addiction, and urged Mexicans to stop idealizing power, money and violence so as to halt drug dependency.

"The problem of drug addiction in our country goes hand in hand with a bigger problem: drug trafficking," they said.

They urged "anti-doping" programs to detect drug use early on in schools as well as increased sports and psychological help for young people experiencing emotional problems.
