LOS ANGELES – California voters, by a modest margin, think they should be allowed to grow and consume marijuana, according to a new poll that also found more than one in three voters had tried pot and more than one in 10 had lit up in the past year.

The Los Angeles Times/USC poll found that voters back the marijuana legalization measure on the November ballot, 49 percent to 41 percent, with about 10 percent uncertain about it. But support for the initiative is unstable, with one-third of the supporters saying they favor it only “somewhat.”

“The good news for proponents is that they are starting off with a decent lead. The good news for the opposition is that initiatives that start off at less than 50 percent in the polls usually have a hard time,” said Dan Schnur, director of USC’s Jesse M. Unruh Institute of Politics.

Men favor legalization, but women are split. Among married women, 49 percent reject the measure while 40 percent are in favor of the initiative.
