Evidence of Effectiveness Needed

"In light of the fact that the phase III evaluation of the media campaign yielded no evidence of a positive outcome in relation to teen drug use and congressional conferees’ indications of their intentions to rely on the Westat study, Congress should consider limiting appropriations for the National Youth Anti-Drug Media Campaign beginning in the fiscal 2007 budget year until ONDCP is able to provide credible evidence of the effectiveness of exposure to the campaign on youth drug use outcomes or provide other credible options for a media campaign approach."
