When Colorado legalized recreational marijuana last year, it opened the floodgates to $700 million in legal sales, orchestra "weed concerts" and the world's first pot credit union. So what would California look like if it legalized recreational marijuana use? The issue could be on the ballot as early as next year, and a task force led by Lt. Gov. Gavin Newsom is studying how the state should prepare for possible legalization. Would pot be sold, as some entrepreneurs envision, in high-end marijuana resorts? Would enforcement become comparable to that of alcohol? In this hour, we imagine a future California where marijuana is legal and examine the economic and cultural implications.
