After watching heroin overdoses rise slowly over the last two years, police in Battle Creek saw a sudden spike in November.
LifeCare Ambulance serves Calhoun County. It responded to 56 calls for heroin overdoses in November this year, compared to 18 overdoses in November, 2015.
Police suspect heroin cut with Carfentanil is to blame, though they are still awaiting the results of lab tests to confirm.
Carfentanil is a powerful opiate sometimes used as an elephant tranquilizer and is 10,000 times more powerful than morphine.
