If you think someone has overdosed on alcohol or drugs, call 911 immediately and state that you believe someone has overdosed and provide a clear address and location.  Rapid response is essential for preventing permanent brain injury or death. The 911 Good Samaritan Law provides protection for the caller from drug possession charges when an overdose victim or an overdose witness seeks medical attention.  Also, if you are close to a person who is misusing or addicted to an opiod painkiller, you may purchase and have on hand life-saving Nalaxone, that can reverse an overdose before it is too late.  Some health insurance plans will cover most of the cost.  You can purchase Naloxone at most pharmacies without a prescription.
