There is a lot riding on the outcome of Ashcroft v. Raich , which will be argued Monday in the Supreme Court. If the Court rules for the Government, lawful medicinal users in nine states may be out of luck. While it will still be lawful for them to use marijuana under state law, the feds will still be able to prosecute them. The Marijuana Policy Project is not giving up, no matter which way the court rules:

"The most important thing to know is that this case will not impact the right of states to enact their own medical marijuana laws," said Rob Kampia, executive director of MPP, which is based in Washington, D.C. "If the Supreme Court rules our way, the federal government's war on patients will come to an abrupt end in the 10 states with medical marijuana laws, On the other hand, if the Court rules against us, then we're back to where we started -- patients will be protected from arrest under state law, but not under federal law."
