It doesn't sound to me like you are talking about closing the adoption, only stopping visits and phone calls. That is within your right to do so..... and I would do the same if I was in your shoes.
It is not your reponsibility to have to take phone calls because she can't give you an address. My suggestion then is to set up a web page on a FREE site and give the bmom the internet address to visit it and see pictures and be able to communicate with you. I did this for my dd first 18 months of life. Bmom did not have a computer or bfather, but they could go to the local library and use it for free.
I would stop all communication with her by phone and any visits until she starts cleaning up her act. Since she has illegal activity, can't hold a place to live and appears the drug use continues and the poor baby was born addicted... YIKES...... I think baunt had the CHILD's best interest at heart. Too bad you can't keep in contact with her.
It's time the bmom grew up and started acting responsible. Good luck on what you decide.
