Brown made his comments Sunday during an appearance on NBC's Meet the Press. He was asked whether legalizing marijuana was a good or bad idea for California.
Brown said the state already has medical marijuana which gets very close to what Colorado and Washington have.
"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.

I think we need to stay alert."
In a wide-ranging interview Brown also discussed California's drought problems, climate change and his future political career.
