Drug overdoses are now the leading cause of death for Americans under the age of 50. There were approximately 59,000 last year, most of which were from heroin or another opiate. That's fucking insane.
I went to rehab a little over two years ago for alcohol and cocaine not really knowing the scope of opiate addiction amongst young people in our country. Obviously I'd hear news stories and shit, but it never really seemed close to me. Most of the kids that were in the two programs I went to were in their for pills/heroin, a lot of whom have since relapsed or died. The statistics aren't good for recovery (just in general, not just for opiates), maybe 10% find any kind of long-term sobriety.
When I got out of treatment I lived with 3 guys in recovery that I had been in treatment with, one of whom had unbeknownst to me had been getting high since he was in rehab. He overdosed in my basement with another guy one night and had to get Narcaned by the paramedics. The kid was facing two years in prison for robbery, was on probation/drug court, and was hundreds of thousands of dollars in debt, yet still chose to get high. The disease (yes, it is a disease) is absolutely mind-boggling.
As someone said, if you know someone struggling with addiction, the best thing you can possibly do is let them know that help is there, but don't force them into anything until they themselves want it. Unfortunately, a lot of times it's too late before they do, but only when the addict or alcoholic is willing to change for themselves after hitting bottom is recovery possible.
