heroin epidemic

I know this isn't pregnancy related but I'm just feeling so heartbroken. I live in an area rhat has a massive heroin epidemic and it's just depressing! A few days ago a woman was at Family Dollar with her toddler and passed out from an over dose. There was a video of it... Her two year old daughter was hysterically crying and trying to wake her and no one was comforting the poor baby. I just can't understand how a parent can ever put a drug before their child and put them in that kind of danger. It's just so heart breaking knowing there are so many children who are in these situations.
