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 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.
