How do I get my dad off drugs?

I (23f) have been going to therapy to talk about how I was mentally and physically abused as a child. I haven't seen my dad since I was 15 and he is a drug addict. I have learned to accept that this is not my fault. I have learned to relish the fact that I got out of that environment with my own two hands and there is zero chance of him coming back into my life. If I ever decide to have kids, I will be the one to break the cycle.<br><br>I want to see if he is okay. Not to fix him or baby him or whatever. Just to see if he is okay. I want to tell him that I'm happy and almost done with college and have a full time job. I want to tell him that I love him and I will always love him, not because I want to be there for him, but because I have learned to accept that I will love him for the rest of my life.<br><br>I do not want to tell him that I'm seeing a therapist. He'll just try to hook me on meth so I can feel better. <br><br>I have been doing research and I don't know what to do. It's hard to get an addict to stop doing drugs, but I want my dad to see me again. I want to tell him to get his life together. I just don't know how to get him off his drugs, and I don't know how to get in touch with him, he doesn't have any social media, but I know he isn't in jail. How do I do this?<br><br>Also, I should be able to do this without going to therapy for another year?
