Chances are good that Californians will vote to legalize pot this November. A proposed ballot measure has wide support. Twenty years ago, Californians approved the measure that legalized medical marijuana use, and since then those working in the cannabis industry have been operating in a kind of hazy legal zone. State lawmakers never bothered to clear that up, until last fall, when Governor Brown signed legislation to establish clear guidelines and regulations for the industry. In the process, he may have ushered in an era of “Big Pot” in California. What happens next?
