They say that here in the US, states are the laboratories of democracy and it’s true: Each and every day we’re running state-sized experiments on ourselves, whether we’re testing out a new tax policy, new reforms to education, or new environmental controls.  Well at the beginning of this year, California launched one off those experiments on a grand scale when it legalized the recreational use of marijuana.  On this edition of In Depth we’re going to finish up our two part series examining marijuana’s impact in California as we near the end of our first year of legal recreational sales.  Last week we discussed how the brand new marijuana industry is fairing as businesses scramble to adapt to a range of new regulations and taxes.  This week though we’re going to look at some of the social consequences of legalization.  First we’ll be looking at what legalization has meant for the criminal justice system, and then we’ll examine what impact it’s had on our kids.  Guest:  Josh Meisel, a professor of sociology and a co-director of the Humboldt Institute for Interdisciplinary Marijuana Research.  Up next we're going to take a look at how marijuana has impacted teens here in California.  Guest:  Danielle Ramo, adjunct associate professor in the Department of Psychiatry at UC San Francisco and the director of research operations at Hope Lab in San Francisco.
