In a letter to former heads of the Drug Enforcement Agency on Wednesday, Attorney General Eric Holder said the U.S. will enforce federal law prohibiting recreational marijuana use and production, regardless of whether Californians legalize the drug through Proposition 19.
The DEA chiefs had called on the Obama administration to sue California if the measure passes.
"We will vigorously enforce the CSA (Controlled Substances Act) against those individuals and organizations that possess, manufacture or distribute marijuana for recreational use, even if such activities are permitted under state law," Holder wrote.
The Drug Policy Alliance, a pro-19 group, called Holder's statement "political posturing."
Also today, L.A. County Sheriff Lee Baca and L.A. District Attorney Steve Cooley said they would continue to enforce federal marijuana laws even if Proposition 19 passed.
