Los Angeles County Sheriff Lee Baca said Friday his deputies’ marijuana enforcement would not change even if Proposition 19, which would legalize the drug in California, passes Nov. 2.

“Proposition 19 is not going to pass, even if it passes,” Baca said in a news conference Friday at sheriff's headquarters in Monterey Park.

Baca, whose department polices three-fourths of the county, was bolstered Friday by an announcement from the Obama administration that federal officials would continue to “vigorously enforce” marijuana laws in California, even if state voters pass the measure.

Baca said the proposition was superseded by federal law and if passed, would be found unconstitutional.

Flanked by other opponents of the measure, including Los Angeles County Dist. Atty. Steve Cooley, Baca made a colorful assault on marijuana use and sales. Asked if he had ever experimented with the drug, Baca was unequivocal. “Hell no,” he said.
