Of course, no State can authorize violations of federal law, and the list of factors above is not intended to describe exhaustively when a federal prosecution may be warranted.
Accordingly, in prosecutions under the Controlled Substances Act, federal prosecutors are not
expected to charge, prove, or otherwise establish any state law violations. Indeed, this
memorandum does not alter in any way the Department's authority to enforce federal law,
including laws prohibiting the manufacture, production, distribution, possession, or use of
marijuana on federal property. This guidance regarding resource allocation does not "legalize"
marijuana or provide a legal defense to a violation of federal law, nor is it intended to create any
privileges, benefits, or rights, substantive or procedural, enforceable by any individual, party or
witness in any administrative, civil, or criminal matter. Nor does clear and unambiguous
compliance with state law or the absence of one or all of the above factors create a legal defense
to a violation of the Controlled Substances Act. Rather, this memorandum is intended solely as a
guide to the exercise of investigative and prosecutorial discretion.
