WASHINGTON- A Government Accountability Office probe of the White House's anti-drug media campaign has found that the $1 billion-plus spent on the effort so far has not been effective in reducing teen drug use. The report recommends that Congress limit funding until the Office of National Drug Control Policy "provides credible evidence of a media campaign approach that effectively prevents and curtails youth drug use."

The report comes at a time when Congress is poised to take up the anti-drug media campaign budget when it returns from its recess. The campaign's current budget is $99 million, the lowest since the effort began in 1998. ONDCP has asked for $120 million next year. The Senate agrees with that amount, but the House has recommended $100,000.
