LOS ANGELES (AP) _ Priscilla Presley plans to speak at the opening of a drug rehabilitation center in Michigan on Saturday.

Presley will help inaugurate the 120-bed Narconon Stone Hawk East residential center in Albion, Mich., spokesman Greg LaClaire told The Associated Press on Friday.

Narconon is based on principles developed by science fiction writer L. Ron Hubbard, the founder of Scientology. Presley is a Scientologist.

The Narconon program is ``capable of eliminating the very cravings that drive addicts in recovery back to drugs,'' Presley said in a statement.

The 61-year-old actress said she became ``passionate'' about recovery after enduring the ``personal heartbreaking experience of seeing family and friends fall into addiction to alcohol or other drugs.''

Her late husband, Elvis Presley, had persistent problems with pharmaceutical drugs.
