The Drug Enforcement Administration has launched a new education program, involving prominent professional and amateur athletes, aimed at reducing drug abuse among young people by 50 percent to 75 percent over the next five years.

DEA Administrator Francis M. (Bud) Mullen Jr. has said the program will sponsor seminars, clinics and public relations campaigns in up to 200 cities to discourage young people from using dangerous drugs.

Mullen said more than 40 organizations will be involved in the program, ranging from the FBI and other law enforcement agencies to parent groups and professional, college and amateur sports organizations.

He said major sports figures will participate in educational programs and act as advisers to school groups. The point of the project will be to spread the word to some 59 million young people -- from kindergartners to college students -- to stay away from drugs.

Mullen said it is an outgrowth of a program started last June in which the DEA began to train 48,000 high school athletic coaches to detect signs of drug abuse and set up programs to deal with the problem. STAYING IN PLACE?? . . .

Webster announced last month that the bureau had negotiated contracts with Coldwell Banker Relocation Management Services Inc. and Homequity Inc. to provide relocation services for FBI and DEA employes.
