Maine law enforcement officials are warning of bad batches of heroin after a spate of overdoses.
The Bangor Daily News reports that police assume the heroin was laced with fentanyl, which is far more powerful than heroin.
The Hancock County Sheriff's Department posted a warning on its Facebook page after three overdoses in Washington County and one in Hancock County. Officials say all of those victims were revived with the overdose antidote Narcan.
