RIO GRANDE VALLEY--The D.E.A. and local law enforcement held a prescription drug take back collection on Saturday.

The drive helps prevent drugs like opioids from falling in the wrong hands.

There were collection site in Hidalgo, Starr and Cameron counties.

Assistant D.E.A. Special agent Stephen Jenkins said there are certain drugs the agency is keeping its eyes on in the Rio Grande Valley.

"A lot of the fentanyl that's being imported into the U.S. is coming through here. So, we're on the watch for that," Jenkins said.

Jenkins said they collected more than 2200 pounds of drugs during the last prescription drug take back day. The drugs are taken to an incinerator in McAllen to be disposed of.

If you miss the drug take back day, many police departments have a box where you can drop off unwanted pills.
