Miami police said officers arrived in the neighborhood around 5:30 p.m. Tuesday and they soon discovered the drugs and a weapon inside one of the homes, The Miami Herald reported Wednesday.
Police said a further search uncovered 10 grenades in a bedroom. They also found a pig in the house.
Sgt. Freddie Cruz said the neighborhood was evacuated while the 10 grenades were taken to a lab to test whether or not they were live explosives.
Two people, a man and a woman whose names were not released, were arrested on drug and weapons charges. Police said they could face federal charges if the grenades are found to be live.
