Support this Bill - “Medical Marijuana Patient Protection Act,” HR 2835

Any estimates on when they're supposed to vote on it?

Pretty sure it's been shelved for the current session. They're too busy working (or whatever you want to call it) on health care reform. The good news is that the number of states allowing medical use of cannabis is rapidly approaching the halfway mark. I think at that point the legislation would undoubtedly pass, since representatives from medical states would have to vote in favor of it or risk falling out of favor among their constituents.
