DAVID GREGORY: 40 years ago, we weren't talking about legalizing marijuana in states either. Is that a good or a bad idea for California?
GOV. JERRY BROWN (D-CA): Well, we have medical marijuana, which gets very close to what they have in Colorado and Washington. I'd really like those two states to show us how it's going to work. The problem with anything, a certain amount is okay, but there is a tendency to go to extremes, and all of a sudden, if there's advertising and legitimacy, how many people can get stoned and still have a great state or a great nation? World's pretty dangerous, very competitive. I think we needed to stay alert, if not 24 hours a day, more than some of the pot heads might be able to put together.
