My ex's new cocaine sniffing girlfriend!!!! Advice please!!!?

I think what you can do is explain your ex about the harmfulness of the cok which he is started out. try to explain him that it will really cause all sorts of problems for him.if he still doesnt stop it try to contact his family and tell about the problem. I hope he stops it from bottom of my heart and best of luck to you. I hope you get success with this issue.
