She should never have the child unattended and she should never be allowed to drive with the child and you should certainly turn her in to the authorities for child endangerment and drug abuse and kick her out of your house. She might live in the streets and she might die but that is a decision she made when she took her first hit. Take your daughter and get far away if you can. Do whatever you can through the legal system. Don't give her chance after chance.   Not one chance ever again. Chances to a meth addict are like nothing. They will lie, steal, do whatever. Your child is absolutely unsafe with her and her creepy friends. Sooner or later she will be molested. If you do not get rid of this horrid woman (who may have redeeming qualities but none that are relevant right now) then turn the child in to foster care for her protection. mg
