Yes its tough. Please keep checking my articles because I will have more that relate to this. Always remember to keep science in mind in this regard. Your brother, our loved ones, have had changes in their brains that make it difficult for them to function in society. I like to think of it, and speak of it, as a broken computer. We shouldn't ask a broken computer to fix itself, and function normally. Often we get upset with the choices our loved ones make, but we don't understand what it is like to have these changes in our brains.
And be careful with your language. It's obvious to me, even with your writing, that you will never stop CARING. It's just that at some point you and your family might have to stop putting energy into your brother, which is fair. You can't waste your own life trying to help another, because that isn't really help at all, and you won't have anything to help them with when they DO seek change. Sometimes you HAVE to un-attach, which is hard, but its true.
But you will ALWAYS care :)
In regard to drugs and especially for example heroine, and science, there are some things that our system and society doesn't subscribe to that can help. Kratom I will write about soon and it is saving my friend. Marijuana I am also a strong believer in. But these things must be used properly and with treatment.
The only advice I might give, is to talk to your brother about EVERYTHING. There might be things he doesn't want to tell you, and that you don't want to hear. But over time he will open up and its important for both of you and important for him. Addicts start to hide the truth and its a very helpful thing for them to feel loved and comfortable enough to open up.
This alone can cause him to seek internal change.
Take care, and hug your family. It's tough, I know.
And thank you for sharing.
