In 1969, 13 percent of Californians favored pot legalization, 49 percent favored harsher penalties for use and possession. By 1983, supporters had risen to 30 percent. In 2010, it was 50 percent, but a legalization measure failed on a statewide vote. Now, the number has risen to 55 percent. That's according to Mark DiCamillo, director of the California statewide Field Poll.
