Want to help my brother
Hi, I'm new here and please forgive me if this thread doesn't belong here and should be moved elsewhere. I have very little knowledge about substance abuse. My mother alerted me that she found something in my brother's room. We found a lot of empty vials, some with liquid in them, syringes (some sterile, some with liquid in them), a bottle of 9 mg/ml NaCl solution, and a heavy yellow glass container containing one of the vials with liquid inside. It's hard to describe because I have no idea what this is. I don't understand why he would be injecting saline solution, or whether this is used to dilute something else? Do you have any ideas what he could be injecting? We hadn't noticed anything out of the ordinary until now and we really don't know how to approach him about this. Thank you very much for any help.
