On December 17th of 2010 a memo was sent out to all Agencies and Department Heads with the intent of ensuring Scientific Integrity. Yet the this is still part of the Drug Czar's Legal Responsibilities.
(12) shall ensure that no Federal funds appropriated to the Office of National Drug Control Policy shall be expended for any study or contract relating to the legalization (for a medical use or any other use) of a substance listed in schedule I of section 202 of the Controlled Substances Act (21 U.S.C. 812) and take such actions as necessary to oppose any attempt to legalize the use of a substance (in any form)
This undermines the ideals of Scientific Integrity and also reduces the amount of information available on reducing harm caused by drug use, abuse, addiction and law enforcement.
