A new task force based in Los Angeles will fight the spread of methamphetamine, California Attorney General Kamala D. Harris announced this week. Authorities say 70 percent of meth enters the United States through San Diego.

Six agents will investigate illegal activities involving the manufacture and distribution of meth, the Los Angeles Times reports.

“Transnational criminal organizations have made California the largest point of entry for methamphetamine into the United States,” Harris said in a statement. In March, Harris issued a report that called the trafficking of methamphetamine a growing threat to the state and a top priority for law enforcement. The report included recommendations, such as increased funding for state anti-narcotics trafficking task forces, and additional coordination between federal, state and local law enforcement agencies in combating transnational criminal organizations.

According to the report, in 2013, border authorities seized over 6,200 kilograms of methamphetamine entering California, a three-fold increase since 2009.
