TLDR; The stuff in the middle is context, but the most important part is the bottom paragraph.

My best friend and his wife got pregnant a couple months ago, and in all likelihood, I'll be the godfather for the child. I wouldn't necessarily be the ideal choice because I don't have a husband or wife (never even been in a relationship) but I make up for that with my ability to commit to the people I do care about. Most importantly, I'd be a far better parent than my best friend could ever be. He's the last person who's qualified to parent a child.
One of the problems with my best friend and his wife are that they both smoke a ton of weed. At this point, they kinda have to. My best friend has really bad ADHD, Bipolar, and Irritable Bowel Syndrome. With the ADHD and Bipolar, he has at least one episode a day where he just insults everybody around him and becomes completely self-centered. His wife doesn't really know what to do about that except ride out the storm. You can't expect that from an infant, though. Back to the weed, though, he smokes a ton of weed because his old drugs were ineffective and made him want to kill himself. Weed gets him to a more reasonable level and he can eat. So... the weed is better.
His wife smokes the weed for neck pain, migraines, and stomach problems. Problem is, she'll be consuming weed until the last few months because she can't really eat without it, and the baby needs food. I've convinced them to stop smoking blunts (they have tobacco) and in general, I think I've convinced them to switched to vaporization instead of smoking. Smoke is obviously bad for the baby. Marijuana probably is too, but getting them to remove tobacco and smoke is the best victory I could get. Regardless, they don't believe weed is bad for the baby.

Anyway, here's what I'm wondering about. If she still has weed in her system when the baby is born, I'm wondering if CPS could take the child and put her in prison for child abuse. I assume this will also be the case when they check in with my best friend and find out he has weed in his system. I'm not sure what really happens though. Does CPS take the baby for their own? Do they both go to prison? Does the baby go to me, the Godfather? And also, if I fail a drug test (and I could, but I don't smoke nearly as much as them), what happens to me? Or is the child taken and we're all left free and miserable?
