Police say a group of men smoking marijuana at a home in northern New Jersey created so much smoke they triggered a fire alarm -- and then their own arrest on drug charges.

Fire officials in Sparta say that when the smoke detector went off, it activated a home alarm system that resulted in both the fire and police departments being dispatched.

The New Jersey Herald of Newton reports police detected a strong odor of burnt marijuana when they got to the house early Thursday but found nobody inside because everybody had fled.

Three young men and a juvenile were later arrested on drug-related charges.

At the home police say they found a glass water bong, a plastic bag with marijuana, a marijuana grinder and other drug paraphernalia.
