The results of tests done on soul legend James Brown after he was arrested Sept. 24--following a two-state car chase--indicate Brown had the hallucinogenic drug PCP in his system at the time, a South Carolina prosecutor said Thursday. Brown in the past has maintained he has never used the drug, but his attorney said the entertainer began treatment in Athens, Ga., this week for “substance abuse.” Brown’s attorney, Albert Dallas, refused to identify the drug, and referred to Brown’s problem as related to “stress-control.” Brown, 55, was charged with driving under the influence after he led police on a chase that started and ended in Augusta, Ga.
