The Organization of American states has ended its general assembly meeting without including the themes of decriminalizing or legalizing drugs in its final declaration.

The three-day OAS meeting was held amid growing frustration in the region over the number of people killed in the battle against drug trafficking.

Officials for several countries including Guatemala had predicted the declaration would include a change in anti-drug policy.

The meeting that ended Friday was also marked by the decision of four countries to withdraw from an OAS defense advisory body.

The leftist-led nations of Venezuela, Nicaragua, Ecuador and Bolivia said they didn't see a need to remain on the Inter-American Defense Board.
