Katie53, welcome to SR...
While anything is possible, unless your daughter was working a program while she was in jail.. then I highly doubt that it was enough time for her to get and stay clean...
3 weeks ago she moved in with a guy. I know nothing about him, not even his name. She doesn't offer any info. and I don't ask. She was here the other day and my phone rang. It was someone I know from her days before jail and they used crack together. She apparently is now in contact with him again
This would be a huge red flag for me... she is still playing on the same playground with the same playmates... dangerous territory for someone who is either newly sober or trying to get clean
She swears she is not using, but my gut tells me differently
Your gut is probably 100% spot on... my gut has never been wrong...
I don't know a whole lot about crack but there are some awesome recovering crack addicts and family members of crack addicts who post here that can give you better advice then me..
