Newksm, oh I wish I wasn't writing this to you but it seems you are in the position of needing to protect the most innocent now, your great grandson. I so hope your grand daughter gets it together but is sure seems like she's not responsible enough to have her son with her outside of your home anymore. This time it was lucky she left him with someone else who is responsible. Next time, who knows. She checked out to go do drugs, and will most likely continue to do so, not caring about her son's physical safety. He's already obviously not emotionally safe with her, something you can't make happen by giving her more opportunities, she's gone right now as far as that's concerned. I think it's time to get a lawyer and discuss what options might be available to physically protect him.
