Gov. George Deukmejian has committed California National Guard volunteers to aid federal drug enforcement efforts in Southern California.

The governor said Wednesday that California was one of several states cooperating in a federal drive aimed at reducing the flow of narcotics into the United States."This is sort of a test to see how well it works," he said during a photo session in his office. "The Congress and president feel the National Guard can be of some assistance."

Maj. Steve Mensik, a Guard spokesman, said the volunteers will act only in support of law enforcement officers. He added, "It's highly unlikely any National Guard troops will be placed in harm's way."
