OMAHA, Neb. (AP) — Communities across Nebraska and Iowa will be participating in the federal Drug Enforcement Administration’s Drug Take-Back Day this weekend.

The program allows the public to drop off unused, expired or unwanted prescription drugs at scores of collection sites across the two states this Saturday.

The DEA says rates of prescription drug abuse in the U.S. are alarmingly high, as are the number of accidental poisonings and overdoses due to these drugs. According to the Centers for Disease Control and Prevention, 91 Americans die each day from an opioid overdose.

The national event was launched in 2010 and is held twice each year. Last October, more than 457 tons (414 metric tons) of prescription drugs were collected nationally.
