I'm at the Students for Sensible Drug Policy West Coast Regional Conference (at SF State -- see http://ssdp.org/conference/westcoast) where Senator Mark Leno is currently answering a question about Proposition 19. This initiative would reduce California's prison population by allowing adult possession and cultivation of 25 square feet of cannabis.
Senator Leno reminds us that California has the USA's highest recidivism rate, 70%, compared to the national average of 35%. California's prisons confine 170,000 inmates, 180% of their capacity of 90,000. Wow!
