LOS ANGELES (CBS) — The RAND Corp. Monday officially retracted a study published in September that linked increases in crime to the closing of marijuana dispensaries around Los Angeles.
Public safety advocates widely criticized the report and questioned the study’s data, prompting the Santa Monica-based think tank to review its study.
The review found the study did not include crime data reported by the Los Angeles Police Department, according to RAND, which plans to conduct a new analysis that could take months to complete.
RAND Vice President of Infrastructure, Safety and Environment Debra Knopman called the retraction a “rare failure” of the company’s peer review system.
“We take our commitment to quality and objectivity seriously so we have retracted the study in order to correct it,” she said.
