How do we stop the meth epidemic from flooding the foster care system?

I think if we took the time to help them, talk them through their problems, and make them see what they are doing to their family that would be more effective. Maybe a therapist should start coming into jails where the parents are. I'm not really sure what would help because people get addicted so easily to meth. I can't believe someone would smoke something that could blow up their face.....
