Responsible depictions of drug abuse won accolades for TV's "ER" and "The Promised Land," along with the film "Down in the Delta." They received Prism awards from Entertainment Industries Council Inc., a nonprofit organization that tries to encourage producers to focus accurately on drugs, AIDS and other social issues. The awards were given this week in partnership with the National Institute on Drug Abuse and the Robert Wood Johnson Foundation. "People have a tendency to think of the entertainment industry as just entertainment, but actually it's the nation's largest and most effective educational system," said Dr. Alan Leshner, director of the drug abuse institute. NBC's "ER" was honored for a story line about the drug-addicted cousin of Dr. John Carter, played by Noah Wyle. "The Promised Land," on CBS, was recognized for an episode about heroin abuse. "Down in the Delta" was honored for Alfre Woodard's portrayal of an inner-city woman helped through drug problems by her family.
