Call CPS....and do it soon...your grand daughter doesn't need to be in that environment. As an educator, I can tell you the results are not good when they child lives in a drug infested environment.

Also, check your state laws on Grandparent's rights. They do exist (at least in IN). A friend of mine got custody of her grand daughter by fighting in court. It's not easy, but, she did it!

Good luck and I will send my prayers and positive energy your direction!
