Ok so, I just found out from a friend of mine, that my brother is doing Meth. He just got out of basic training for the Army National Guard not too long ago, got a job at Sam's Club, and seemed to be doing good. Now, I found out today, he's no-call/no-showed to his job for the past week or so, and he's been doing Meth with a few other kids I knew from high school. I've already informed his girlfriend about it, I'm sure she had no idea.

Already talked to my mom, she doesn't know he's doing Meth but she knows he's up to something. She's going to take his keys away and boot him out of the house. So, I guess what I'm wondering is, should I call his commanding officer for his unit and tel him they need to give him a drug test? Or, should I just let it play it's course. I'm so angry right now I'm shaking, and I don't want to do anything that will make him do something he's going to regret. Our dad committed suicide in 2010 and I'm scared he may do the same.

Help...
