Police Chief Allen Krajcik called last week for anyone accompanying a person experiencing a drug overdose to make a good-faith ambulance call without concern for the possibility of arrest. Krajcik’s concern stemmed from a rash of opiate abuse around the region, and an avalanche of overdoses locally. He said Massachusetts General Law Chapter 94C, Section 34A – or the Good Samaritan Law – protects people who call for emergency medical services for someone in that danger. “All too often, people are hesitant to call for an ambulance when a friend is overdosing for fear of being criminally charged with possession of drugs,’’ he said in a news release. “Delaying medical attention to an overdose victim can lead to death or brain injury.” Krajcik said police normally respond with the ambulance to medical calls but if drugs are found as a result of someone calling 911 for aid an overdose victim, officers cannot charge either the caller or the victim for possession of drugs.
