My brother has always had addiction problems. He has a long past of meth. I once tried to help him quit, but that's another story...he relapsed and continued to do meth for many years and I stayed out of it. Especially during the time I was quitting my drinking/party lifestyle and getting my degree in another state. Recently, I have noticed a shift in his behavior and it seems like he is doing heroin or something, he has the nodding off tendencies a lot lately. I am not sure if he is also using meth still...I went over to his house and there was someone outside waiting for him, the guy asked me if I was getting "brown" which I am pretty sure means heroin? I haven't spoken to him about it, but he is usually straight forward with me and doesn't hide his life choices from me, but he does from other family members. It feels like a huge burden, because I feel responsible for helping him with his problem, but also don't want to spill the beans to my family and have everyone freaking out (him and the rest of my family). I don't really get how my family doesn't pick up on signs and cues that he is doing drugs, but they have been oblivious for years. I really can't see him again without saying something to him because I am really concerned. I have read on other forums that people only nod when they are heavily dosing...is this true? Also, if he is high will he take me seriously about my concerns?
