CHARLESTON, W.Va. -- A record number of unused and expired prescription drugs were dropped off to police across West Virginia last weekend, federal prosecutors said.The annual drug take back event held April 27 netted 4,642 pounds of medications, according to a news release from U.S. Attorney Booth Goodwin's office. That's 70 pounds more than last year, the release states.Around West Virginia, more than 100 drop-off locations were set up. This is the sixth year the nationwide event has been held in the state. "This year's record total is another milestone in the fight against prescription drug abuse. West Virginians understand how devastating the prescription drug problem is for our families, and they're responding in the most effective way they can: by getting rid of potentially dangerous medicine that they don't need any more," Goodwin said in the release.
