Basically a death sentence for many people. My younger athlete daughter is a firefighter EMT. She sees this crap every day. 911 calls for teenage kids with their resting heart rate at 230 saying they didn't take anything. Scary stuff... "The National Institute on Drug Abuse states that between 40 and 60 percentof recovering drug addicts will eventually relapse. With heroin, those rates are even higher. Some experts place the rate of relapse for heroin addicts as high as 80 percent, which means that the recovery rate may be as low as 20 percent."
