Where there's smoke, there's fire but inside a Miami-Dade warehouse Thursday, firefighters found out there was something else burning.
Inside the warehouse at 13771 NW 19 Ave., firefighters found flames and budding marijuana plants, officials confirmed.
Firefighters got the call for the fire at around 3 p.m. An illegally-built mezzanine prevented crews from going inside the building safely, but firefighters were able to contain the fire from the outside.
Opa-Locka and Miami-Dade police investigators will be back at the warehouse Friday to search the marijuana lab
It's unclear what started the blaze.
So far, no one has been arrested. No word on how much marijuana was in the warehouse or who leases that unit.
The news comes just days after the U.S. Drug Enforcement Administration released a report that shows Florida has more hydroponic marijuana grow houses than any other state, with 818 labs busted last year. South Florida leads the state in the number of labs.
