Tell the 911 operator you suspect someone is experiencing an overdose. Missouri's "Good Samaritan" law protects people who call 911 in response to an overdose from arrest and prosecution for possession of drugs and other minor violations.
STAY AND WAIT FOR HELP
Put the person on their side with one arm supporting their head and their knee bent to prevent rolling onto stomach.
Stay with the person until medical help arrives.
If they stop breathing, begin making gurgling or snoring noises, or their breathing slows down significantly, you will need to begin CPR.
Revive is NOT a replacement for calling 911 or any other public emergency services. Illicit or “street” drugs, especially those obtained from unknown sources, could be laced with dangerous substances that can only be treated for in a health care setting. If you are in immediate danger from a medical emergency, call 911 and/or the appropriate authorities IMMEDIATELY. Revive is meant as a resource to help you administer life saving aid while you await the appropriate public emergency services.
