If Noah has made several attempts and is using class 1 drugs, I'm sure he is drawing more attention to himself than just you. What makes you think you are the one to help him? You mention Eli's age, but not yours or Noah's. Maybe this is above your pay grade?
I'll share a situation which occurred with me. After moving away from my home town, I returned for a family reunion. I hadn't seen my younger brother for a few years, but I talked to him occasionally. He is married with two young teen aged girls. When I saw him I almost
didn't recognize him. He looked to weigh under 170lbs. His previous weight was an athletic 220lbs. He had stitches in his head. His girls were sporting piercings and tattoos. He had been fired from his job. I said "what's up?" He gave me a bunch of lies. I told him, I'm going
to get you the help you need and I only ask one favor. Don't lie to me again. And of course the next words out of his mouth were lies. What really hurt me was his girls were my mother's grandchildren, and the entire family was looking away from what was before them.
I went back home and called his city's social services. I said "he is on heroin, his wife is using heroin, drug dealers are in and out of his household and he has two young teen daughters." They said "we got it, and you are now out of the picture." They kicked down his door
and put his kids in foster care. They got him the help he needed. I buried him in March after his 20th anniversary of being clean and sober. I wasn't in a position to help him directly, but I knew who to call.
