State attorney general Roy Cooper says 3.5 million doses of potentially dangerous prescription drugs were collected in a single day of events statewide late last month.
Cooper's office said Monday 20 percent of the more than 8,000 pounds of drugs collected on Oct. 29 were controlled substances like hydrocodone and methadone.
Local police worked with the U.S. Drug Enforcement Administration and the State Bureau of Investigation at more than 150 locations to collect medications residents wanted to drop off.
Cooper's office says Jacksonville police collected 158,000 doses, the Moore County Sheriff's Office collected 190,000 doses, and Greensboro police collected 419,000 doses.
The drugs were safely destroyed at an incinerator in Burlington.
