Police and city officials in Houston said evidence in storage lockers is being destroyed by "drug-addicted rats."

The Texas city’s mayor said he will work with the county district attorney to discard drug evidence obtained before 2015 that no longer has any value.

Police in Houston are currently dealing with drug-addicted rats who have acquired a taste for weed, cocaine, and other illicit drugs.

The rodents are enjoying marijuana at the Houston Police Department that has been sitting in evidence for years.

"We've got 400,000 lbs. of marijuana in storage, that the rats are the only ones enjoying it," said Houston Mayor John Whitmire.

The Houston Police Department, the Mayor's office, and the District Attorney's Office are teaming up for a holistic approach to battle the weed-eating rodents.

The Houston Police Department says its methods for storing seized drugs have gone up in smoke after it was discovered that rats have been crawling through evidence lockers with a major case of the munchies and gobbling up the marijuana being stored in criminal cases.

To illustrate the problem, Houston police Chief J. Noe Diaz pointed to one piece of cocaine evidence from 1996 that was still in the lockup. The individual tied to the drugs pleaded guilty, was sentenced to 20 years in prison and has since been released, he said.

The property room contains a backlog of thousands of pounds of evidence that is no longer needed, including notes from a homicide that occurred in 1947, and kilos of cocaine from the 1990s.

The Houston Police Department and Harris County District Attorney's Office announced changes to their procedures for storing narcotic evidence after an infestation of "drug-addicted rats"
