In November 2016, Proposition 64 was passed in California allowing for the legalization of recreational cannabis use. The measure came into effect on January 1, 2018 with California joining 28 other US states that have legislated for the medical and/or recreational use of cannabis. Cannabis legalization in California is expected to generate $3.7 billion in sales in 2018, but requires policy initiatives to mitigate potential negative environmental impacts. California is in a unique position to create a sustainable cannabis industry.
