This just popped up in my inbox:

The Department of Justice is reviewing the legalization initiatives recently passed in Colorado and Washington State. The Department’s responsibility to enforce the Controlled Substances Act remains unchanged. Neither States nor the Executive branch can nullify a statute passed by Congress. In enacting the Controlled Substances Act, Congress determined that marijuana is a Schedule I controlled substance. Regardless of any changes in state law, including the change that will go into effect on December 6th in Washington State, growing, selling or possessing any amount of marijuana remains illegal under federal law. Members of the public are also advised to remember that it remains against federal law to bring any amount of marijuana onto federal property, including all federal buildings, national parks and forests, military installations, and courthouses.

Marijuana becomes legal at midnight, hurrah! But in light of this momentous occasion, it would be best for everyone if we handled tonight's transition like adults—not by courtin' the bull and lighting up on federal property or other foolishly public places, yeah?
