Doesn't sound like he was her kid at all. Kid didn't live there, appeared healthy, happy, and didn't have signs of abuse.

My guess is his mom/dad is related to whoever has a drug problem.

I don't think active addicts should be around children (whether meth, booze, or whatever else), but he's also not getting removed from his parents nor is the addict his mom.

Also, criminalization of drug addiction doesn't solve the issue. If it did, we'd have won the war on drugs by now. Doesn't sound like she's committed property or violent crimes. Just that she's sick. Arresting her isn't helping anyone.
