<human>: Hi redditors! I hope I am not posting this in the wrong place. My brother (23) who has been clean for three months had a seizure Saturday. This is his first seizure and they think it is related to withdrawal. There were no drugs in his system when they tested his blood at the hospital. 

So, he's been on drugs for a couple years...about 5~7 years, actually. We haven't talked very much the last few years because I've tried to help him several times before without success, but we were younger then, still teenagers. 

Now, he has a six month old daughter and after this seizure, I really believe he wants to change..especially since his tox screen came back negative. We have other half siblings, but he's never opened up to them like he does with me. I feel like I'm the best chance he has. He would be honest about his drug use with me. Even when we weren't super close, I'd still do birthday parties and holiday stuff for him.

I'm letting him move in with me because he isn't supposed to be alone for 6 months. I want to make him feel welcome and like he can talk to me about anything, but also make sure he stays clean. Do you guys have any advice on how to help him feel welcome and like he isn't being judged? This will be the first time since we have lived together in 5 years. I'm a nurse, so I feel that he would be safest with me. I know this is a gamble, but he is tying to better himself and I think everyone deserves a second chance. I am not one to deal with bullshit however. I have dropped him before because of his lifestyle, as well as my oldest sister because of her drug addiction. My brother had mostly smoked pot (who hasn't?) and was hooked on pills. I'm sure he's probably tried harder drugs, but I'm not sure what. No signs of anything intravenous though.

Can you give me a shortened version of the text?
