As hard and uncomfortable as it might seem, you might want to discreetly report her to the Police… it just might save her life.
Pretty Judgemental Anon…
There is hope for Addicts anon.. they aren't all homeless and/or hopeless throwaways. I happen to be a former Addict with 2 young boys. I also have sole custody of them, and their mother wasn't an addict. Recovery and a good life and future is possible.
