This is an important Bill because it encourages research by hospitals and Universities. The restrictions against anyone who every have even a minor conviction for marijuana use is not warranted in my opinion. This passage in that article is important:

“While this vote marks a step forward, it must also be acknowledged that despite existing barriers to research, ample studies already exist to contradict cannabis' federal, schedule I status as a substance without medical utility, lacking acceptable safety, and possessing a high potential of abuse," NORML Deputy Director Paul Armentano said in a press release. "More clinical research is welcome, but unfortunately science has never driven marijuana policy. If it did, the United States would already have a very different policy in place."
