NIDA's mission is to lead the Nation in bringing the power of science to bear on drug abuse and addiction. Critical components: first is the strategic support and conduct of research across a broad range of disciplines, the second is ensuring the rapid and effective dissemination and use of the results of that research to significantly improve prevention and treatment and to inform policy as it relates to drug abuse and addiction.
